Every summer, RMI climbing teams consume over 7,000 gallons of drinking water at Camp Muir, the primary camp on Mt. Rainier's Disappointment Cleaver Route. For many years, melting snow in a large barrel heated by propane created drinking water for Camp Muir. We knew that there was a better way to provide drinking water to our teams and it just required a little bit of creativity, brainstorming, and initiative. Over the course of the 2012 and 2013 climbing seasons, a new solar thermal system was installed at Camp Muir. This system, designed to use environmentally benign and free solar energy to efficiently melt snow, provides drinking and cooking water for RMI climbers and guides at an elevation of 10,060'. The system was designed and built by RMI Guide and alternative energy professor Mike Uchal and his colleague Dr. Brian Raichle, who is a professor of solar energy technology at Appalachian State University. RMI Guide Cody Doolan also contributed with the design, installation, and maintenance. RMI's Solar Snow Melt System, part of our commitment to Responsible Climbing, reduces our environmental footprint on Mt. Rainier by minimizing the need to burn liquid propane gas in order to melt snow, cuts our operating costs, and reduces the environmental footprint of the helicopter used to transport propane to Camp Muir.
How it works:
A small electric pump powered by photovoltaic panels pulls water from the burn barrel, a large barrel used to melt snow, uphill to a solar thermal collector. The collector, a conventional flat plate solar thermal collector is the kind that is typically used in residential and commercial domestic hot water systems. The water is pulled by gravity through the copper pipes in the collector and is heated by solar radiation before returning to the melt barrel. RMI guides keep the barrel fed with clean snow from the snowfields above Camp Muir and this snow mixes with the warm water and melts into liquid form. A controller turns on the pump in the morning and off at the end of the day when the sun goes down. Because the collector is uphill of the barrel, gravity drains water from the collector at night to prevent damage from freezing water. This system design eliminates any problems associated with overheating during late season conditions when solar energy can be plentiful and strong.
How it performs:
On warm, sunny days at Camp Muir, typical in the late summer, the solar snow melting system heated the 30+ gallons of water in the burn barrel to above 100°F. That is nearly spa temperature! On cold, sunny days, often found early in the season, the system heated water to temperatures above 40°F - enough to effectively melt snow. Propane is still used during storms that last several days, when solar radiation isn’t strong enough to heat the collector, but the solar snow melting system dramatically reduced the amount of propane burned during the 2013 summer climbing season.
Anecdotally, before the 2013 climbing season the propane burner was running for around 3.5 hours per day to melt enough snow to provide drinking water for the RMI teams. During the 2013 climbing season, guides estimate that the burner was needed on average around 15 minutes per day. During the summer climbing season of 2013, we estimate the solar system saved approximately 250 pounds of propane, the associated cost of transport that propane, and 0.33 metric tons of CO2 emissions.
This project is part of RMI’s commitment to the outdoor community and environment as we work to reduce the environmental footprint of our climbs in order to ensure that many future generations are able to enjoy the same mountain environment that we enjoy. The RMI Solar Snow Melt System is a great example of practices that can reduce a business' environmental footprint and provide cost savings at the same time. By the end of its first full year at Camp Muir, the system paid for itself with savings in fuel and helicopter transport costs. The next time you make it to Camp Muir, swing by the guide shack and check it out! The guides would love to show you the system in person.

I am currently signed up for the Rainer hike this coming Summer. I have done Devils Path in Catskills, NY which is 25 miles, 10,000 ft of climbing in 12 hours as well as climb Mount Mitchell in NC which is about 8 miles and 4,500 feet of climbing which took about 2 hours. I obviously will have ample time between when the 16 week program ends and my hike. Is there any suggestions for me to continue to keep in shape between the end of my training program and my hike? I know I am in good shape for the hike through trying hikes like I mentioned above but wanted to know how I continue to stay on that level. Thanks!

I’ve been down since labor day. My inner thigh started cramping at the end of a hike, cramped through the night, then stiffened up. The following day the skin was very bruised like I had bumped it but I had not. It’s still sore. Before and during the hike I was hydrating with clear water and occasional electrolytes because I seem to have cramping issues, but I don’t remember sweating very much. It was a cool, dry, sunny day and I was often in a tee shirt. Maybe I was evaporating off more than I realized? Truthfully, I had cheated on the training a little. I thought I was ready for a fun 13,600’ spring climb of Mt Dade in the Sierra Nevada, spring snow fields, and an overnight pack. It was only a 4 mile 1000’ ft elevation approach to an 11,000’ base camp, which is where I started cramping and turned back from the next day. It was a bear descending. I’ve been doing nothing since as far as training, but I’m going to start up again. Any advice on recovery training, and preventing this kind of injury on the the next big hike?

It was another breathless, warm morning on the Ecuadorian countryside. Our beautiful hacienda was situated perfectly in a giant valley which runs directly from our dining room window unabated for 7000’ vertical feet straight to the summit.
Chimborazo, the farthest point from the center of the earth and closest to the sun, was mostly displaying her majesty as we sipped coffee and ate our eggs. As the morning wore on, she hid herself from view and we loaded the magic bus ready to take us to the Chimborazo trailhead. By 1:30 all our packs were packed, and it was off to high camp at 17,500 feet.
At this altitude nothing feels perfect, unzipping your trousers just to take a pee can leave you winded. But our seemingly invincible team has again handled things with grace under pressure and is doing well up here. Once again, the Ecuadorians have done it right, providing a giant dome tent for our lounging pleasure.
But don’t get too comfy bloglandia, the alarm is set for a mere four hour from not. It is then we will have our final test?
The is rest well with a positive psych ! Wish us well!

Hello again everyone,
All is still well here in the Khumbu as the team members made our way back to Pheriche. It was a busy day on the trail with climbers, Trekkers, yaks, and porters all bound uphill to basecamp. We slowly made our way through the maze of traffic and enjoyed a few last good views of Everest.
Pretty amazing how thick the air here at 14,000' feels compared to 17,500'. Spirits are high even with slightly tired legs after an eight hour day!

Adjusting to the low oxygen of high altitude environments is a natural process that we will all experience if we travel or live at high altitudes. Like all things in life, some people are better at adjusting to high altitude than others. Fortunately, there are ways that each of us can prepare at home and in the early stages of mountain travel before going to the big peaks.
We all experience the low oxygen of high altitude a little differently, but the most prominent symptoms of going to high altitude are categorized as the condition Acute Mountain Sickness (AMS). AMS is composed of a group of symptoms that can present themselves after spending some time at high altitude. Symptoms of AMS include headache, fatigue, anorexia, nausea and insomnia. While the severity of these symptoms can vary, AMS does not have to end your climb but should be used as an indication that your body is struggling to acclimatize.
The most important aspect of performing well and staying healthy in the mountains under the stress of low oxygen is by being physically fit. If you have been following a rigorous training program then you are well on your way to being physically fit for your climb. Fitness cannot prevent the symptoms of AMS but if the daily physical tasks of climbing are easier due to your high fitness level, then you have more energy reserves to battle the stress of the low oxygen environment.
Proper nutrition and hydration are also important variables leading up to and during your climb. While you may avoid simple carbohydrates during daily life, at altitude simple carbohydrates are the most efficient and most preferred form of energy for your acclimatizing body. Don’t be afraid to eat those high glycemic foods while working hard at altitude!
Dehydration can certainly be detrimental to your performance and health at high altitude, but you do not need to constantly consume water. Listen to your body, specifically your thirst, it has been finely tuned over many generations to keep you hydrated.
The prescription medication acetazolamide (Diamox) can help with acclimatization to high altitude, but it is not a magic pill that will solve all your high altitude problems. Diamox has repeatedly reduced AMS symptoms and hastened acclimatization during multi-day clinical and laboratory studies. It can work and is a great tool to use if you are not acclimatizing during an expedition even though you are using a standard acclimatization schedule, but its efficacy is less known for a quick overnight summit attempt such as Mt. Rainier. Remember: all medications have side effects that you need to understand before using and Diamox will not make up for a lack of fitness when headed into the mountains.
The bottom line is make sure that your body is fit enough to handle the stress of a high altitude mountain trip, and listen to your body while you are at altitude. If you pay attention, your body will tell you what fuel you need to keep going and how well you are adjusting to the high altitude environment. Have fun and climb safe!

The trip came to life three years ago when three Canadian skiers hatched the idea and began the logistics. I was brought on because the team wanted two more experienced ski mountaineers for the remote and relatively unexplored zone of the Pamir mountain range.
Having traveled in developing countries before, I knew that I not only wanted to travel, climb and ski in this remote range, but to give back to the mountain communities that would help inevitably help us on our adventure along the way. As I packed my gear for the trip I noticed how much great warm clothing I had to choose from and I realized that I didn’t even use half of it anymore. This was it! I could get people to donate the winter clothing they hadn’t used in years and put it to good use in a country where access to technical apparel was slim to nil. I began a clothing drive and between me and my teammates Holly Walker, Emelie Stenberg, Vince Shuley and Selena Cordeau, we were able to collect and give 350 pounds of clothing to give to the Tajik people who needed the clothes far more than we did.
The good vibes from the clothing drive started our trip on a positive note - which was good, because it was a long, hard trip. We planned on one week for getting on and off the tributary glaciers to get to and from the Fedchenko. It ended up taking us thirteen days, nearly twice as long. We planned on setting up three basecamps and skiing 6000m peaks for two weeks; we were tent bound for six of those days due to weather. On top of all that, the snowpack was just about as unstable as it could get. This greatly limited what we were able to climb and ski.
Despite the hard work and frustrating snowpack, we had an amazing trip. Massive valleys, towering peaks like Peak Ismoil Somoni (formerly Peak Communism) and Independence Peak (Peak Revolution) and miles of ice surrounded us in a grand scale. We were in a place that few people had been before and completely isolated except for our DeLorme InReach two way satellite texting device. It was humbling and inspiring.
We met our goal of traversing the Fedchenko from our starting point in a town called Poy Mazor to its head and descended out the beautiful and rugged Tanimas Valley. Due to the exploratory nature of this trip and having little information about our exit, we left ourselves a few extra days before we would all have to fly home.
Our extra days were spent regaining some of the pounds we lost during the expedition eating fresh tandoor bread, kebabs and local apricots and cherries. People greeted us everywhere and invited us to share bread and tea with them even if they couldn’t speak a word of English (and we could only muster hello and thank you in Tajik).
The team left Tajikistan with a good taste in our mouths in more ways than one. We explored and lived in a high mountain range for 29 days, were exposed to the kind and generous culture of the Tajik, Pamir and Afghan people and came home safe!
Thanks to the Eddie Bauer/ RMI Guide grant for assisting me in this amazing pursuit. The lessons I learned on this trip will forever shape my decision making and goals in the mountains. Until next time...
