Cheap Portable Laptop Power – Matt, Andy
Matt Swarts and Andy Quitmeyer came up with a way to cheaply power laptops and other high-voltage devices off cheap powerpacks! Difficulty: Medium-easy. We cha
Laptops demand lots of power. They also usually need to charge from voltage source that is much higher than the 5 volts you can get out of cheap cell-phone charging powerpacks. This means that usually you have to get a really expensive power-pack (like this one for $100) that can output the 12-20 volts that your computer needs. These power-packs also need a higher-voltage themselves to start charging, so they are much harder to get charging from my solar panels than other cheap 5V packs.
Instead you can now use something cheap like this 5V power supply that only costs $16.
and all you need is one extra simple part that can boost the voltage for only $4!
How to Build
- DC Booster
- Batter Pack
- USB Cable
- Laptop Charging Cable (you can use a “repair” cable that is already pre-spliced for you too! )
- Wire Strippers
- Alligator clips (or soldering iron)
Just connect the positive and Ground from the power-pack to the “IN” ports of the booster. Then connect the + and – ports on the “out” side to the laptop charging cable (you can get cheap “repair” cables that have nice leads already pre-taken out.
Set the Voltage!
Now before you rush off to plug this thing into your laptop you need to set the voltage booster to the correct voltage. Some voltage boosters have a built-in display that lets you know what they are set to, but others you will need to connect a multi-meter.
Find the original charger for the laptop and make a note of the voltage that your device requires. Rotate the small flat-head screw on the top of the booster until you get the correct voltage. Boom, any of the even moderately hard parts of this how-to are done!
Now for jut $24, I have a slim power pack that can recharge my laptop TWICE!
PhotoSphere – Matt
Part of the experience of hiking in the wild is the dramatic flow of changes in light as you move through the forest. To capture part of this experience we created a cap with photo sensors on it to record the changes in light patterns as we walk. The cap was made before we left for the wilderness.
[image of cap]
We created the PhotoSphere with 16 photo-resistors meticulously sewn into the cap. Each photo-resistor needed a 1000 ohm resistor as a voltage divider to be able to extract the voltage changes. A typical Arduino only has 6 analog analog-to-digital converters (ADC). We used an Arduion Mega instead, which has 16 ADCs.

The Succession of Trees – Hugh
The Succession of Trees
The Tennessee/North Carolina Appalachians are renowned for their diverse tree population, and our trek took us from 4470 feet at Unicoi Gap to the Citico Creek Campground #14 elevation of 1720, providing an altitude-inflected arboretum. Different areas were logged off over the years, so at the higher elevations most were younger than in the lower areas, but of course we benefitted from hiking on old logging roads and a rapidly disappearing railroad grade.
There were the constants– rhododendron forming the familiar Appalachian green tunnel and, at least in these forests, a preponderance of maples. Early we hiked amongst those maples, a few poplars, several species of birch, and what looked like a buckeye tree (though I could only find one rotten buckeye on the ground). What stopped everyone in their tracks were the monumental dead hemlocks. The Wooly Adelgid is rapidly decimating the hemlock population in the area, leaving behind standing dead trunks that still loom ghostly over the surrounding forest.
Descending further down were fewer dead hemlocks, along with a number of smaller live ones, the occasional hickory, very large maples, and finally a few oaks (they were noticeably absent higher up). Soon the tulip poplars started to dominate, and around the base camp were the largest in the forest. Turning from the largest to the smallest, there were a variety of club mosses including one which was nearly six inches high, and a lot of stubby Sassafras trees. Located only in our camp was a specimen of the nearly extinct Owl tree (see picture), and just down from the base was another campsite located in a grove of mature beeches–the light, filtered through the leaves, was the greenest of green.
I love moss. I really do. I love moss so much that I can’t help but write about it. Moss is indeed one of the Great Things. Moss is like a sedative and its porous structure imparts such a stillness to its surroundings that the sound it absorbs seems to manifest as a physical presence. It’s as if moss must consume sound in order to survive. Moss loves dampness and decay and the forests of Citico Creek provide an ideal substrate for huge bryophytic colonies. A porous absorber, moss converts a minuscule portion of the acoustic energy it consumes into heat. Dispersing that heat as waste is perhaps what make moss seem so cool.
LED Feelies (for wilderness plants) – Andy, Laura, Jeannette
BOB SOS: Back off bear alert – Jeannette, Hugh
Context: First, a report that a young boy was lacerated by a bear in a forest near us and a suggestion that we build a bear detector. A week before, JY learned how to solder and program an arduino to make an LED blink like one of the firefly species. A day before, she got 2 servo motors to shake a noisy shiny piece of mylar. We took these starting points from the lab into the forest: NFCCDL: North Fork Citico Creek Digital Lab.
bear bag is placed away from camp
Marketability: In the forest, product took a practical side, shifting from an alert of mere presence of a bear to a lightweight, compact attachment to a camp tent to alert the camper.
Capability: Need to see all around so need to figure out how to station the system on the peak of tent to expand the perceptive field. There is no need to know direction, only presence.
Interaction with nature: design an output that would scare a bear.
Detect the presence of a bear near the tent.
Wake up camper inside tent.
Simultaneously, start up a set of blinking lights in shape of eyes separated by a distance to signify a large size that could scare a bear.
input: sensing system 4 motion detectors
output: LED to scare bear and buzzer to wake camper in tent
Input: 4 Motion detectors, range of 20 ‘ and 90 degree cone of detection.
Control system: Arduino, breadboard, battery pack
Output: LEDs, buzzer
Make a 3D attachment site for sensing system: a magnolia bud that smells like oregano.
Make platform for control system: a flat piece of oak bark
Get output to appropriate locations: long lead for buzzer to inside tent, 2 leads to scary LED eyes sewn onto a fabric with face-like decorations to hide wiring.
Programming a scary message to a bear: flash out SOS in morse code on LEDs and wake up camper with a buzzer using same program.
Attachment to tent: used set of strong magnets
BOB SOS in place on hammock tent tarp
Incident: unaware of a bear attractant still remaining within the tent
Bear approaches and is detected.
Camper is alerted and bear is scared off by illumination system.
Simplify attachment to tent.
Test whether bears are scared by flashing lights that look like eyes of something bigger than themselves.
Backpack design: Projection system as part of the function of backpack. -Jeannette
Scientists often rationalize that our advancement of knowledge is equal to the costs of the lives of living organisms. It isn’t. I took disdain at this idea.
Instead, with the advances in modern high image resolution in time and space of the digital age, we now can produce large magnified images that are comfortable for humans to view. This gives us the ability to observe living creatures in the wild without disturbing the community. One of the items I’d like to carry in the backpack would be a compact projection/image recording system: a vellum-like sheet onto which a lit Fresnel lens could produce a crisp magnified image so we could see the part of nature that is smaller than trees and birds. The camera looks into the lamp by focusing on the back of the image screen. Therefore the lighting doesn’t have to be super bright.
To my surprise, we actually did try to set up a projection system. It totally worked! It was too dim to easily take a picture of with a camera, but in the dark forest, it was awesome to share a picture, or video at a large scale for many people to check out at the same time!
Amazing Lifeforms at the NFCCDL (Owl Camp) – Angela
Maybe the mountains imprinted themselves in my dad’s DNA during his childhood in South Korea, and those highland genes are what always draw me to the spectacular sights and sounds of southern Appalachia. While camping in Joyce Kilmer National Forest, I was completely awed by all the life that was around us, and the cool, clear weather during most of our trip allowed us many opportunities to enjoy the incredible array of flora and fauna near our idyllic base camp by Citico Creek.
While the 6-foot tall Hugh was contemplating the taller trees in the forest, those of us closer to the ground had our eyes focused on the plants near our feet. The pipsissewa, or striped wintergreen, had white berry-like buds and were just beginning to bloom. Traditionally, the leaves have been used medicinally for ailments ranging from rheumatism to kidney problems. The plant does have antiseptic properties and is still sometimes used as a flavoring for candy. We had just missed the lady slipper orchids and only saw the spent inflorescence, but we were too early for the rattlesnake plantain orchids. There were a few Indian ghost pipes, which are named for their white, nearly ghostly appearance due to the lack of chlorophyll. The wildflowers were growing amongst the groundcover of partridge berries surrounding the trees.
Around the edges of the base camp were young sassafrass, which attracted black swallowtail butterflies. There were also a few silver spotted skippers. Both of these species, however, were greatly outnumbered by the Appalachian azures that congregated around our site like a gathering of forest fairies.
Our more earth-bound neighbors included a definite tussock moth caterpillar that had yet to earn its wings. On the first day, we had picked up an oil beetle using a stick and managed to avoid the chemical it secretes to cause blisters on menacing predators. Shiva named one of the queen crater snails in our camp “Squickie” and its leopard slug cousin “Slickie.” Andy preferred the colored flatbacked millipedes and the giant North American millipedes, whose defense mechanism is to secrete a chemical containing cyanide, faintly scenting them of almonds. I came to think of a large fishing spider that lived in the dead tree above my head as my pet away from home.
Although Shiva and I had some perturbed mammalian visitors by our tent on the first night hiking to the campsite, we didn’t spot as many vertebrates near our home base as we expected. We did hear a variety of birds: sapsuckers, a barred owl, red-breasted grosbeaks, cardinals, sparrows, wrens, chickadees, and warblers, including the black-throated green warbler whose mating call sounds like the Teenage Mutant Ninja Turtles theme song – “Heroes in a half shell!” Laura caught a Southern toad on the trail, and Andy and Shiva startled a rattlesnake on their afternoon run. In the water, I managed to catch one of the smallest salamanders in the world, the pygmy salamander. It was so translucent that you could see all its internal organs and its beating heart.
While wishing for someone with foraging knowledge to prepare us a camp meal, we came across some chanterelles a quarter of a mile from camp. After scaring ourselves with horrific fungus poisoning stories, we left the chanterelles in the forest to decompose the decaying matter around them. The damp conditions were perfect for the toadstools, shelf fungi, and coral fungi. Their fellow decomposers, slime molds, also populated the fallen rotting trees. The log outside my tent became covered in white, marshallow-like poufs almost overnight. Other logs were covered in slime molds of various shapes, colors, and textures.
The striking thing about the wildlife we saw was that quite a few are threatened or endangered, particularly in certain parts of their habitat ranges, and very few opportunities are left to see these species. Having the chance to see these organisms was certainly a wonderful experience. However, our hiking hack aspired to garner the potential of technology – something that seems to be incompatible with nature – to encourage people to engage with the natural environment and instill a sense of stewardship. Helping to preserve these natural wonders – that is a truly exciting prospect indeed.
The Night Crawler, he was called!! – Shiva
After a long day at the SCCDL (South Citico Creek Digital Laboratory :P) and a great Turkey Tetrazinni and Raspberry Crumble, we decided to take a stroll to observe some fireflies!!
We merely walked around a hundred yards from base camp. We used flashlights to reach the observation site. However, we had to stand or sit in the dark so that we can observe the amazing flashes of the hundreds of fireflies around us. To be honest, that was a scary moment for me. Standing in the dark, with god knows how many different crawlies all around me inching towards me…whooooaaa!!
While fighting the urge to scream in terror, I focused on the fireflies. Everyone was shuffling around to get a better look at flying mini-bulbs. You would imagine bunch of people with no sense of environment around them trying to shuffle slowly using hands and feet to sense around, bumping into each other and trees around us. Not the most efficient way to go about it, you might say.
There was this thought though, what if one has to hike at night without a light source due to some reason. Using hands and legs to sense the environment, obstacles and even approaching bears at night!!
As we were already using our hands, I conceptualized a wearable product with a ultra-sonic distance sensor which can keep you informed about your surrounding by bouncing off ultra-sonic waves just like echolocation done by bats.
After understanding the dimensions of the sensors and board as well as the idea of keeping your hands free while hiking, I brainstormed for different mounting options along the body.
For the initial prototype, I decide to go with the ‘Head Band Design’ as it could be a complimentary device to human eyes.
The first prototype was really simple. It used fabric as the base to support a small platform and attach the reflective straps. The Arduino Theo along with input and output sensors were supported on the platform using threads to tie-down.
The sensor has a range between 2cm – 400cm. The buzzer’s frequency increases as the hiker approaches an object or vice-versa. The emergency light which is a small LED (tested in the field for amount of light) turns on if the hiker is in a hitting distance of an object. For the first prototype we used a safe distance of 10″.
FUTURE DESIGN IMPROVEMENTS:
+ Use of multiple sensors and outputs to give a sense of direction to the hiker.
+ Exploring form factor, to be placed on different body parts
+ Exploring a combination of sensors to enhance efficiency.
Etho-Smock In the Field – Laura, Katelyn, Paul
Here’s a short commercial “skit” describing its use!
When designing the wearable aspect of the Etho-smock, we considered several factors critical for successful and convenient field use.
- Device needs to be lightweight
- Comfortable in the heat
- No interference with natural body motion (i.e. not tangled in arms or legs)
- Compatible with field work
- able to be worn standing, sitting, or squatting
- able to wear simultaneously with backpack
- easy to transfer device between users in the field
- packability, can be compressed
We ultimately decided to pursue a smock inspired design.
This allows the device to be transferred easily from one researcher to another by simply lifting it over the head of the user. It can be worn simultaneously with a backpack.
We made the smock with a mesh. This made the device lightweight and breathable for the user to wear and we were able to weave the wires connecting the buttons to the microcontroller into the material of the smock.
Gimme shelter: Animal Homes in the Wild – Jeannette
This week, I left the hot sticky stoney enclave of urban/campus life at Georgia Tech in Atlanta and entered the cool dappled forest of Tennessee. I brought my own home with me: a hammock tent. Instead of carrying a support system, I used the structures in the forest, namely the trunks of rhododendron bushes. At the second site, taking the experience of the first hammock pitch, I pitched by tent close to rushing creek separated by dense bushes where the fireflies flitted in the night. The suspension system of the hammock fit in between and above a nice depression in the ground to give me clearance to stand below the tarp that protected me. My head faced the shrubs with the creek just beyond. Wrapped like a larva in a silk cocoon, the hammock rocked me to sleep like a sailing boat moored in the sea. This is my forest home, comfortably providing a swinging seat and a supported sleeping platform that was sheltered from the rain and wind, excluding unwanted biting insects but allowing views of nature while in the distance, laughter reached me from my Hiking hack comrades around the campfire.
Once my nest was built, I went to a habitat familiar to me: the aquatic community. When I was little, my family home was bordered by 2 brooks. I spent hours looking under rocks for salamanders and crayfish, moving pebbles to make pools to watch them play with each other and their surroundings. I watched snails and slugs crawl, and recently I’ve spent hours watching pteropods flap and spin, so it was easy for me to mimic one that was hallucinating as one of my character roles in our evening performances.
To my delight, after picking up only a few large stones in a still pond off the main rapids, I found some caddisfly pupal homes: tiny tubes made of sand grains.
Stuck to the underside of a larger stone, these cocoons faced into the flow in the still pool of the side of the stream. A laser light passed right through them so no one was inside these homes. Aligning the purple laser with the axis of the tube home, thin shafts of light escaped through the stained-glass-like windowpanes of clear sand grains
When I searched upstream closer to stronger flows as the creek ran down steeper terrain,
the cocoons were constructed of bigger stones. The neatest discovery was that the cocoons looked like little flies: were the caddisfly larvae selecting sand grains that matched in size and color [red] to place them where eyes might be located?

Now I wanted to know if another site would show me another form of their home. three stone houses in a row on underside of stone facing into stream flow

Near this location, the little aquatic insects cemented smaller sand grains of slate, making a grey dense strong tubes,

Reflection: It’s More Than Seeing Yourself in the Creek – Katelyn
There are specific tools used in back country living and digital making. When we combined these tool boxes into heavy backpacks to bring on our expedition, we brought the infrastructure to support the most critical tool, our minds.
My daily life as a hiking hacker began with coffee at the creek side. A warm drink with at least a little bit of caffeine is critical to both my making methodology and my backcountry lifestyle. With the constant rushing of Citico Creek and the caffeine through our veins, we would open each morning writing in our field journals, often responding to a prompt or design challenge. We would finish each night with a reflection on the day’s work and experiences and document each activity as it happened. Our journals became a way for us to communicate with ourselves and the other hiking hackers.
One of the most valuable parts of this expedition was the opportunity to live in the milieu we were drawing inspiration from. On the first morning in base camp, we searched for scents. Not only did we wander the woods sticking our noses unusually close to any and all forest inhabitants, we needed to find a scent we could collect and return to the camp to share.
Forced to engage with my surroundings in a novel way, I found myself asking fundamental questions about my perception. The first descriptor I thought of for the scent of a mushroom was ‘woodsy’ but what does that mean when everything is in a forest and inherently ‘woodsy’? Descriptors like meaty, rotten, warm, rich crawled through my mind, but all of these descriptors crossed senses. What does this indicate about the way I understand the woods? Am I constantly creating a coherent representation of my surroundings with little differentiation between modes of perception? Should I be striving to separate my experience of the senses? When I ideate and build a digital device for interacting with nature, should I attempt to create a unified representation of nature or break it down into different aspects of our surroundings? What are the consequences of each of these design choices? Is translating one sense to another enhancing or detracting from our experience of the nature? Or are we simply changing the experience and broadening our understanding of the world around us, without positive or negative connotations of that change? My conclusion from this smelly meditation was that there is no wrong way to explore nature, given that my exploration does not harm or change the world around me.
The point of sniffing things wasn’t only to experience the woods in new ways, but to reflect on the experience, our perceptions and senses, what we want to build, how we want to build it, and why we want to build it. Reflection like this is the key to hiking hacks and any joint making/exploring project.
A Day in the Basecamp Life – Laura
Setting up for Wildhacks – Andy
On the first day in basecamp, I sent the crew out on a “Smell Adventure.” The goal was to help them explore their environment in new ways by giving them the fun task of collecting as many unique smells from the nearby areas.
While they were out, I started organizing and setting up electronics at our amazing new hacking stations. When they got back we labeled and shared the smells, and then built some more furniture for hacking!
The Most Useless Machine (Without an Arduino) – Paul, Hugh, Laura
The party boat activity prompt was just to take a bunch of outputs and link them together in a way that might stimulate some sort of organism.
Basically, it’s just use a combination of natural and digital materials to make a thing that makes noises and flashes lights and things like that. While digging through the boxes of components, we found one of these thumpers (solenoid from SparkFun) that moves a shaft when a current is applied:
Photo by SparkFun
Hugh suggested that we might be able to use the thumper as a switch, to turn on and off an LED. I immediately latched on to that idea for several reasons: it sounds really fun and weird, it would act as both a switch and an output (noise, vibration), and most of all, it didn’t require a microcontroller to get create some sort of behavior. Using microcontrollers in the NFCCDL (North Fork Citico Creek Digital Laboratory) comes with enough minor problems (writing the software, using up batteries to upload the software, driver issues on the laptop, etc.) that I, personally, wanted to avoid it as much as possible. I also just like the opportunity to design circuits that don’t require them, because it’s a bit more of a challenge for me, given my limited knowledge of electrical engineering.
So we started figuring out how to make the thumper turn itself on and off. I started out thinking that we circuit could constantly supply current to it, but when it thumped, it could short the circuit and turn itself off. That’s the wrong way to do it. It shorts the LiPo, which is bad, and it’s a more complicated circuit, which is also bad. So Andy suggested that we set it up so that whenever it is unthumped, the circuit is completed and it thumps, which breaks the circuit and unthumps itself. Here’s the circuit we came up with:
This circuit is pretty much a single component version of “The Most Useless Machine EVER”. This is actually an interesting short history of the most useless machine, which apparently was first described by Marvin Minsky.
Once we had a good idea of how to make this thing work, Laura gathered a rhododendron branch and wove some LEDs into the leaves and Hugh whittled a connection point for a little gear motor that would make the whole thing spin while I wired it up and built a mount for the motor so that it could make and break the connection consistently.
The mount for the thumper is a piece of cardboard that I cut off the back of my journal and taped to a mini breadboard. The breadboard has two pieces of copper tape on it (once connected to +3.3V and the other connected to the positive lead of the thumper). The thumper has a piece of tape of copper tape on the end of the shaft that sticks out when it is not triggered that spans the two piece of tape on the bread board, so whenever the thumper is not triggered, its positive lead connects to the positive terminal of the battery. The other lead of the thumper connects to ground, so whenever the thumper is untriggered, it completes the circuit and triggers itself.
Getting that working was really exciting. It made quite a bit of noise and vibration, which was perfect for this project, and I could tune the on/off frequency by pressing the thumper closer and tighter towards the breadboard.
Next we wired up the LEDs to the circuit in a way that they would turn on and off with the thumper (positive leads to the same copper tape as the thumper’s positive lead and negative leads to the ground). We used a bunch of clip wires to do this, which completely avoided soldering or stripping wire. We connected the gear motor to positive and ground so it would spin the whole time, but the branch wasn’t strong enough to handle that and the wires would have gotten all twisted up, so we kicked that bit out of the party.
We tuned the thumper a bit to make the blinking of the LEDs visible and stuck on the obligatory googley eyes and showed off our creation. It was really satisfying to make something so wild with such a small BOM and labor. Here’s the finished partyboat, the simplest, most useless machine that is actually pretty useful:
Hydroelectric Power from Citico Creek
We tried to generate power from Citico Creek using a fire hose and some sort of generator. This was originally Scott Gilliland’s idea, and we volunteered to put this craziness to the test by carrying an extra compatible hose all the way down the mountain with us!
We were trying to make it entirely gravity driven, but the place we were at on the creek didn’t drop far enough to create enough pressure to work with the equipment we brought.
Attempts to create a portable system for harnessing energy from rushing water. A 50-foot firehose was placed upstream connected to a PVC opener. At the low end, an electric generator was attached to hopefully created electricity. This generator was not useable with low-pressure systems, and thus a different generator will need to be attached in future trials. The basic proof of concept seems valid however!
The fire hose was so heavy that the water wouldn’t even push the sides out enough to get unobstructed flow. Basically the hose was restricting flow through it. Also, the generator we brought was designed for higher pressure that we could create, so the water flowing through it wouldn’t even turn the turbine.
We could solve these problems from two different directions. We could have hike up in to the mountains to find a suitable waterfall, so that we really could have gotten a 50ft drop from the 50ft fire hose. That theoretically could have generated enough pressure to turn the turbine, but getting a hose to the top of a waterfall isn’t exactly easy, and if there’s not a waterfall near the campsite, getting the batteries to the base of the waterfall and on dry land isn’t really convenient.
Better would be to bring gear more suited to the environment and task that we were dealing with. We now know that in the location we were at the creek drops about 5 feet over 50 feet of length. We could calculate the pressure that could generate and find a hose that works with that low of a pressure and a generator that works with the pressure also. We’d generate less voltage, but there are ways to deal with that, like a voltage booster, that would do the job for recharging batteries.
We tried building our own, low-power generator from a small vibration motor and a plastic cap. It delivered about 50 millivolts of electricity. This amount is quite insignificant, but it does prove the entire concept of harvesting electricity in a quick portable way from nearby water sources is valid. if anyone has suggestions of good, pre-existing turbines we should use, let us know!
We came prepared to jump start a car when all we really needed was to trickle charge a LiPo. Next time, we’ll be even better prepared to harness the power of the water!
Portable Studio Design
Many of our initial thoughts for the design of a fully portable digital crafting studio have been loosely compiled in this, yet-unpublished, paper:
Portable Studio Practice – Wear and Tear – Quitmeyer Perner-Wilson
Where am I? You are here. – Paul
June 11th, 2015
The first day of hiking was easy, until it wasn’t. I had planned it to take two days of walking to get to the NFCCDL (Owl Camp), but the early part of the day had been so easy that we’d gotten optimistic that we could make it in one day of walking. That turned out to not be the case. It started getting bad when we realized that my map was out of date and that the terrain would be somewhat different than we’d expected. At the end of the day, we had hiked 7 miles and still just ended up completely exhausted and camped on the side of a waterfall. It really was for the best that we stopped though. If we’d kept going, we wouldn’t have made it to basecamp before nightfall, and there’s no way Andy and I would have recognized it in the dark.
The second day of walking started out only moderately difficult, at least compared to the end of the first day, and it just got easier. Andy had scouted ahead and found the place we had eaten lunch on our scouting hike a few weeks before and had reported that the trail went downhill a lot and that it flattened out as it got closer to the creek bed. But when the group got down towards the creek, we never passed any landmarks that we recognized.
As I walked along the creek, I got more and more concerned that we had either missed our target or that it was much farther away than we thought it was. I didn’t see our lunch spot, and I didn’t even recognize the trail. We weren’t passing terrain that seemed familiar at all, and I didn’t remember walking on a raised spot in between two branches of the creek.
I’m getting more and more skeptical when Andy runs back up the trail and says that he thinks he’s found the campsite but that he needs me to come take a look, because he’s been having the same problem. He didn’t remember passing our lunch site today, and the campsite looks quite a bit different.
I followed him down the trail and took a look at the site. It looked similar, but I didn’t think it was the same place. Something seemed off, and I still didn’t think we were on a part of the trail that we’d seen before. But there was a nice fire ring, and a little knoll next to the creek with a couple trees that were just right for a hammock. Whether it was the right site or not, it would make a good site, and people were getting a bit restless (and maybe doubting my navigation and planning abilities). Each hiker who trickled in to this perfectly acceptable, yet possibly unknown place, asked a version of the question, “Is this it?” I had to answer that it seemed like maybe but that I wasn’t sure (not a very good answer).
We decided to eat lunch there regardless and to take a little break. While others ate, Andy and I walked down the trail a bit looking for anything we recognized, but all I saw were obvious landmarks that I definitely did not recognize. I was certain we’d never hiked this section of trail before and couldn’t reconcile the fact that that campsite looked so familiar even though nothing else did. There was a tree nearby that had been struck by lightning, which I knew could have happened since we’d last been there, and I was willing to accept that things may have changed, but I needed at least one more landmark to be certain.
Andy finally spotted it: the beaver dam. It’s probably not a real beaver dam, and it didn’t look the same anyway, but sure enough, there was a bunch of sticks blocking a branch of the creek where the trail crossed it, and you could either cross in the deep end or the shallow end over a kind of weird drop in some rocks. Andy wasn’t convinced it was the same, but I was.
We walked back to the quizzical looks from the crew eating lunch at the basecamp. Andy said he was like 75% sure it was the site. I said 90%. We hemmed and hawed until I saw the stick Andy had stuck in a hole in a tree, exactly where’d he’d left it on our scouting trip. This tipped the scales for me. There was no way we weren’t there, although Andy played the skeptic for a few more minutes. The thing that convinced Andy was me getting a GPS reading on my phone that showed us pretty much exactly where we thought we should be (that’s a discussion for another post though).
This experience had a pretty profound effect on me. It had only been three weeks, but so much had changed. Different plants were blooming, some severe weather had knocked down some trees, and we eventually figured out that there had been some really significant trail maintenance that changed things. Even a place established to minimize the impact of people can change with the blink of an eye, and when you aren’t accustomed to the landmarks and signs that do stay relatively constant, you can stand in the exact same place and think you’ve never been there. It’s very disorienting, and it made me want to learn or develop techniques for avoiding it. How can you observe and annotate the important landmarks in the wilderness? What even are the important landmarks in the wilderness? And if they change, how do they
change and how can you learn to see what was there before? Creeks rise and fall; flowers bloom and wilt; trees fall and crush other trees, and people clear the brush from the trail. Maybe environmental consistency is a human construction and requires concrete and alphabets to establish and maintain. Change may be the only constant, and when you’re confronted with it, how do you relate it to the things that you are actually certain of?
I don’t know, but we camped in a wonderful location for several nights. It began to feel very familiar, and each day I began to notice little things that had changed from the day before. Even though I felt comfortable, the forest seemed new and different every time I woke up. By normally living in an environment that is so severely controlled, maybe we forget that one of the things that makes the wilderness wild is the fact that we aren’t the thing that has control over the environment. And maybe, for me, that’s the thing that bothers me (in a very mild, non-confrontational way) about the core concept of the hiking hack. Are we going to the wilderness to tame it, or are we going there to observe it, and where is the line between the two?
