JMT trip report

2012-08-26

Jess and I throughhiked the JMT August 2'nd to August 18'th. So here's a bit of what happened. P1020345

Jess did the planning for this one, so there should be an article coming on that topic at some point. I'm going to focus on the results ;). Nick, Jess' friend from highschool joined us for the first part of the trip. As background, we loaned him an 8x10 tarp setup, and a thin sleeping pad.

In short, the trip was absolutely gorgeous, I still need to filter through the photos.

The hike starts at 4000 feet in Yosemite, and ends 210.4 miles later (according to wikipedia) at 14500 feet on top of mount Whitney. In between, most days go from ~9000 feet through a pass at ~12000 feet and back. We did ~16 miles most days. In contrast to previous trails there are relatively few trees (just in the valleys) and a lot of marmots. We were surprised at how few birds of prey that are up there. The high Sierra are rather striking in that you regularly can see ~20 miles to where you were or will be, but rarely can see much more than that due to other mountains obscuring the view.

The whole story:

We really weren't sure how long we'd take, we had 3 mail drops, and Jess and I had off through the 23'rd. Nick had to get back a bit sooner, so figured he'd hitch or grab a bus (more on this is Jess' post). Suffice to say, we had no place to be for bit.

Review: Squeeze tubes

2012-08-26

This is going to be a quick review... don't buy them. IMG_20120819_134004.jpg

We were in Muir Pass Hut on the JMT at >12000 ft. Chatting about food, someone gifted us a pile of almond butter and Jelly... Let me say that again, someone gave us food they had carried to 12000 feet... As a backpacker this should seem surprising and odd.. Why did they do this?

Because they were leaking all over the place! We figured we didn't care, and in fact carried them a ways without them leaking much (after they weren't very full). That said, if you "overtightened" the lid of either (that is, if you got it even near tight) it would pop past the threads. The backs of the tubes surprisingly didn't seem to leak, but the threads at the front were just crappily made.

So, what should you use instead?... Anything else. How about a plastic jar from cheap peanutbutter?

Actually, On second thought... do use them, and give them to me at 12000 feet :D.

(These tubes have been safely disposed of in a trash can).

Backpacking computer: first attempt

2012-08-25

Why a backpacking computer

This may seem a bit out of charactor... but secretly (or maybe not so secretly) Jess and I are currently software engineers by day.

While we were hiking the JMT we got to chatting and came up with the idea. As I thought about it the idea of a backpacking computer got more and more enticing, here's some uses we came up with:

Of course, there are some requirements. To be useful we'd want wifi so we can upload when in towns, some good IO for things like radios, a good keyboard for typing, a display you can see in the sun, and most importantly incredible battery life.

Lastly, I'm a computer nerd, it has to run Gnu/Linux, or to me it just isn't useful.

My initial idea was to build something from scratch with a black/white passive segment display (you know, old-school style). After poking around a lot and looking at what devices *do* exist, what's easy to build these days, etc. I eventually decided before getting to crazy I should just start with my "cellphone". That is my Samsung Nexus Galaxy Android phone (basically a tiny tablet). I actually carried it on our last trip anyway in case we needed to look stuff while trying to hitchhike home.

Here's what I got: P1020366

My cellphone is a gnu/linux box! (and still a cellphone).

How

First step was to unlock my phone and install CyanogenMOD. I simply followed the directions here: here . Cyanogen is just an open-source android, which I wanted anyway. It comes with a more feature-full Linux kernel and it's already rooted, both of which are needed for Gnu/Linux to work.

Next I tried a couple things, but the winner was the "The Android Complete Linux Installer" available on Google Play. This tells you how to set up a chroot environment, gives you a link to some system images, includes some nice scripts for starting things, and allows installation of Debian among other distros.

For some reason it installed Debian "Lenny", but whatever it's a starting place. Next step was to ssh in from my laptop (thus giving me a reasonable keyboard) remove a few bits of junk I don't want (dbus, xcfe, etc.) and upgrade the system to unstable. This took a bit of doing, I ran out of disk once, crashed the system a couple of times, a few freezes etc. Eventually it worked though and since I successfully upgraded everything's been stable.

The installer sets up a vnc server running xfce. It turned out just removing xfce and install fvwm was sufficient to swap the window manager. I prefer fvwm and it's plenty lightweight.

Next I did a bit more hacking to lock down root, switch to a modern sudo environment, install a proper vim, copy configs from my other machines for vim, bash, and generally set things up the way I like. And what I now have is a fully up to date proper debian install, with X support and all running on my phone. I simply vnc into it from the phone itself and I can swap to debian as a normal android app, no problem!

Note that before using debian you have to start it up, this is *good* because it means I won't burn any battery power when just carrying my phone around as... you know... a phone.

Future Work

I have a usb adapter on the way to see if I can get my old usb folding keyboard to work on the device. If not I can use bluetooth if I have to. I need a solar charger so I can keep the battery topped up while I'm out.

Once I have a basic computing device I can really use, I can try it in the backcountry.

If it all works out I may look into software controlled USB HAM radios so I can chat with people using hardly any power from the backwoods :P.

The Nook eink reader is android based and has already been rooted. I might be able to do the same thing to it and have a passive display eink reader that hardly burns any power at all, especially when being used for reference material. http://www.flickr.com/photos/smalladventures/sets/72157631243912642/

Caloric density of food

2012-08-25

I'll be honest. I've always bought backpacking food by wandering around the grocery store and grabbing anything that had a decent number of calories and a fast enough cook time. We did mail drops for the JMT though so for the first time ever I did a bunch of Kcal/oz calculations. The results were surprising enough that I made a spreadsheet of them for your enjoyment: the data


General observations

Caveats

Do you have any favorite camping foods I'm missing?

Gear for the JMT

2012-08-01

Jess and I are about to embark on a trip on the JMT with a highschool friend of Jess'.

I reworked my gear several times in the last couple of days, trying to get the weight down. I sat and weighed everything going in my pack. Here's a spreadsheet of my gear and weights: https://docs.google.com/spreadsheet/ccc?key=0AsHrPt9gwuHadEkwb3Y5X2ItWU9mR3pVZy1CZE1PZEE

Some interesting points of note: Jess is carrying the tarp for both of us, though I have the hiking poles (used as tarp poles) and groundcloth. We're both carrying stoves since Jess' friend isn't bringing one. I bought a rain-pancho and dropped my rain-coat, since I'm not really expecting much rain. It should be warm so I dropped my down vest, and silk bottoms. My quilt is warmer than needed so I also dropped my bivy in favor of a groundcloth. I'm also going to use a very thin sleepingpad.

In reality I've got more shelter than needed. I have a groundcloth, a poncho, and an emergency bivy. But I don't trust the poncho (it's quite fragile) so I don't want to use it as a groundcloth. I'm going a bit minimal on the warm clothing side, so I'm happy for some warmth backup with the emergency bivy. And of course, I need some rain-gear. Yeah, I'm a wuss, but I've been screwed by untested gear before.

My total weight is as heavy as it is, despite trying to drop weight, for several reasons
  1. Bear canister weighs 2.7 lbs, and because of it I need a heavier pack
  2. I wanted a fishing rod and tackle
  3. I have a woodstove
  4. my sleep-system is way overkill
  5. I want to record the trip, and want my smartphone to help with getting back
  6. I have a bit of extra gear because I don't trust some of it

All combined this brings what could easily be a 6-8 lb base-weight up to 14 lbs. I've got ~3 lbs I could scrape off easily given dropping a bit of gear I don't need. I could scrape off another ~2 lbs off my pack if I wanted to go frameless. After that it gets harder, I could get ~1 lb out of my sleep-system if I bought a 30 degree quilt. If I could get out of yosemite in the first day and camped in designated spots in some areas I could swap the bear-can for an ursack saving ~2 lbs. I could actually get away with no tarp if the poncho works out, but this'll be it's first test.

Anyway see you in 3 weeks!
