Doggone Cold! Winter Gear List for Dogs

Winter on Mary's Rock

Here’s a list of the winter hiking and backpacking gear that M’s Seeing Eye Dog Edge used on our winter Appalachian Trail adventure in Virginia for New Year’s. This list includes the gear he used for climbing up to Mary’s Rock with wind-chills of -15℉, as well as the gear he used for his first winter overnight (with a record-breaking low of -2℉).

A Walk in the Woods: A Thru-Hiker’s Movie Review


The view from the Chestnut Knob on the Appalachian Trail in Virginia.

I was cautiously optimistic as I walked into the theater with my mom and dad to watch A Walk in the Woods… the trailer looked good, the cast sounded awesome, and I believed that there was plenty of comedic gold in Bryson’s book for the screen-writers to work their magic with… My optimism didn’t last long… The movie lacked coherency, character development, and to my surprise, it even managed to dilute the parts of the book that I thought were funny, and highlighted the parts that I thought were awful… I didn’t love the book, but I’d recommend it over the movie any day!

Heat Wave (Days 70-74)


Virginia has definitely been full of weather extremes. We went from record breaking rains and flood advisories directly to record breaking high temperatures and heat advisories.

At first it was exciting to finally see the sun again! Such a novelty, but as the heat index rose higher and higher it became apparent that excessively high temperatures, like excessive rain, make hiking a challenge.


Trail rumor goes on and on about how nice and easy the terrain in Virginia is, but I’m not sure that I buy it. Sure, there are some nice easy rock-free stretches, but North Carolina, Georgia, and Tennessee all sported some of those as well. There are also lots of rocky, kind of obnoxious sections of trail, like “the roller coaster”.

I got to the roller coaster in the middle of the heat wave. From the elevation profile, it was clear that the roller coaster was named because of the rapid succession of ups and downs. I was hoping that it also meant that it was nice, fast trail… Roller coasters are fun when they are fast, right? Unfortunately, this was not fast trail. It was all incredibly rocky and full of ups and downs. The heat index of 119F might also have colored my opinion of that stretch of trail.

I trudged up and down and up and down through the roller coaster as buckets of sweat poured off of me. I was just as wet as I had been in the rain! Though this was a warm, sticky, smelly wet…


My mom had assured me that she was going to bring the sunshine with her when she came to visit me, but I wasn’t quite prepared for this much warmth. She is exceedingly good at everything she does and this was no exception, so I shouldn’t have been surprised.

On the upside, mom and dad supplied me (and all of the other thru-hikers they met) with lots of food and cold sodas. They also hiked in the heatwave to celebrate the 1000 mile mark with me. Patches and Patches’ parents… You can see the resemblance in our packs (all lined up at the 1000 mile sign to mark the historic occasion).

Snow White (Days 66-69)


Sometimes my life on the trail feels a little surreal. Most mornings I start my hike with my head in the clouds… Or at least a dense fog. The fog hangs in the trees and gives the forest a certain fairy tale quality.

I stepped out of the typical morning cloud, crossed Skyline Drive, and paused on the other side to read the trail sign. I was definitely off in my own world when I heard a car honk. I looked up, and a car had stopped in the middle of the road about 20 feet from me. The women in the passenger side rolled her window down and asked, “Would you like a piece of fruit?”

Fresh fruit is akin to thru-hiker gold. It’s hard to come by on the trail since it’s heavy and bruises easily, so offers of fresh fruit are hard for us to turn down. It was a slightly strange scenario, but I thought about it and I did want a piece of fruit, so I said, “yes”, as I turned and walked back towards the car.

The woman in the car rustled through the paper bag beside her, pulled out an apple, and presented it too me with a flourish. “Here, have this apple” she said with a smile.

My stride faltered just a smidge and I said, “This feels very Snow White to me.” The women smiled again and assured me that they were hikers, and at the last overlook one of the thru-hikers had told them that fruit was better than candy out here on the trail.

I took the apple, thanked the couple for it and headed back towards the trail. As I re-entered the woods I kept thinking about Snow White. I had been offered (and gratefully accepted) peaches, bananas, oranges and even watermelon from strangers on the trail, but in those cases it just seemed like the weird and awesome trail magic that it was. Being offered an apple somehow came with more cultural baggage than I’d expected. Not just of Snow White, but of Adam and Eve in the Garden of Eden. Those stories both seem to suggest that you shouldn’t take and eat apples offered to you by strangers! Or should you?

I looked at my apple again. It was just an apple. I was thinking about this way too much. I took a bite and kept walking. Though it still felt like I was walking through a magically enchanted forest I didn’t fall into a deep, long slumber until after I’d hiked 20 more miles, and I think that slumber was related to exhaustion and not to the very tasty apple.

Inhaler Physics (AT Days 64 & 65)

The skies opened up once again and began dumping rain on me at 1-2 inches and hour. I sighed and resigned myself to getting soaking wet again… The same thing had happened yesterday and the day before. Today, however, I only had two miles of hiking left and then I was headed into town to a nice dry hostel.

Even though I’d resigned myself to getting wet, the thunder, lightning, and really heavy rain weren’t making it the most enjoyable of experiences. I was hiking at about 2 miles/hr so I figured I only had about an hour of uphill in the rain to go. Suddenly I had an epiphany, if I jogged I could be out of the rain in 30 minutes or less… That would be much better than hiking in the nasty nasty weather for an hour!

I tightened the straps of my pack and with water streaming down from the sky and through the trail I started running. It felt good to stretch out my stride and navigate around the rocks and roots.

Not long after initiating this plan the slope of the uphill increased and I realized that I’d forgotten something. I’d forgotten that I have asthma. Doh! I stopped running, pulled out my rescue inhaler (which I always keep handy), and almost hungrily inhaled the medicine that would make it so that I could breath comfortably again.

However, instead of getting the usual easing of my breath as my chest opens up and my lungs full with air, I felt a caustic burning of my throat and lungs and if anything it felt like my lungs constricted even more.

Shocked and confused and now definitely having an asthma attack I looked accusingly at my inhaler. Had I
Accidentally grabbed my pepper spray instead? No, it was definitely my inhaler that I held in my hand. Perhaps it had gotten some sort of particulate in/on it that I had just accidentally propelled into my lungs (everything gets dirty when you’re backpacking). I carefully wiped off the mouthpiece inside and out and took a second puff of the inhaler sure that I’d fixed the problem and would soon be breathing easy again.

F***!!!! Burning, searing, pain as my lungs really ceased up. I threw my inhaler onto the ground; I threw my backpack onto the ground; I threw myself onto the ground. Stupid inhaler, why was it hurting instead of helping?! For the moment I didn’t care. I closed my eyes, leaned forward onto my knees and focused on breathing… It was starting to work, but I was still coughing and feeling short of breath. I reached over and grabbed my water. It soothed my throat and after a couple of minutes I’d stopped coughing.

I was still short of breath, but at least I could think again. What the heck had happened with my inhaler? I remembered the trouble I’d had with my inhaler at the ice hotel in Quebec City over the weekend. It was so cold outside that the inhaler wasn’t working… A common problem with canisters of compressed gases at low temperatures… And suddenly I was thinking about the ideal gas law (PV=nrT), and the compressibility of gases, and thermodynamics.

Was my inhaler acting up because of the weather? It was around 90 degrees out, 100% humidity, plus a low pressure system with a severe thunderstorm raining 2 inches/hr on me. I decided that somehow I must be having the opposite problem from Quebec City, that the compressed gas from the inhaler was still rapidly expanding as it hit the tissue of my throat and lungs. Since the expansion of gas is endothermic, that could essentially burn my throat and lungs with intense cold.

I had a hypothesis… Could I test it? Hmmm… I reached over and picked up my inhaler, which was still sitting in the middle of the trail where I’d thrown it in frustration and anger, and looked at it for a minute. My hypothesis was that the weather conditions were causing the compressed gas in the inhaler to expand over a larger area than usually, so that a noticeable endothermic reaction was still occurring as that compressed air hit my lungs. Based on that hypothesis I would predict noticeable plume as the inhaler was puffed into the open air around me instead of into my lungs.

I pointed the inhaler away from me and delivered a puff over the trail. It looked liked the white plume of breath that you see when someone exhales moist air on a cold winters day… Except that it actually had a propellant, so the plume extended out for about 3 feet.

I was still short of breath, so now I needed a plan. How to get the drugs from my inhaler into my lungs without giving them frostbite? I decided to use my hand as a spacer tube, hoping it would allow the gases to expand in my hand and not my lungs, while still directing the medication into my lungs.

With some trepidation, I squeezed down on the inhaler and inhaled (rather cautiously this time). It worked!!! No horrible burning sensation, and my lungs started to open up. I took a second puff the same way, and my breathing returned to normal.

Now I *really* was drenched. The rain kept pouring down as I walked the rest of the way to the road. I made it in 45 minutes.

Extra credit assignment: Demonstrate mathematically the crucial parameter/s (was it the humidity? the thunderstorm? or a combination of the humidity, thunderstorm, and temperature?) that led to the inhaler doing more harm than good. If I were at home I would have modeled this already and figured out the critical parameters both for this story and for the ice hotel… I miss having pencil, paper, and the easy ability to look things up and research them!
