Cottonwood Instructors Jessie and Ruthie joined Boulder County for a Lefthand Outdoor Challenge winter skills day at Caribou Ranch. Written by Ruthie Cartwright.

We open our eyes and look at the materials in front of us with a clear mission: to build a shelter by nightfall that will keep at least one of us warm and protected. The students are looking at a cornucopia of potential materials: tarps, p-cord, hiking poles, shovels. They are broken into teams and given a mission to go find an already started shelter spot, assess the area and their needs, and send a runner to fill a sled with their materials at the sound of a bird call.
Shovels digging, snow flying, cords knotting, and about fifteen minutes later, we had a shelter tour on our hands. We examined issues as a team in looking at each shelter: where was the shelter and why? We talked about building close to our resources, in this case either in or close to a deep snow drift, or a pre-existing wind break of much-larger-than-human boulders (and of course making sure to avoid dead-fall and potential hazards!). We asked what was working about each shelter, and what needed work? We used this activity to explore the pros and cons of different shapes (circle, square?) and dimensions (ideally at least 2-3 ft deep) of a shelter and how to most efficiently capitalize on our body heat (bringing our legs into our core in the fetal position as well as building small spaces not much larger than our own bodies to not have to use our body heat to warm any more space than needed).

The key piece of our scenario that was the least realistic is what we might actually have on hand for a day hike. If this were to happen to you, what materials from your day pack might prove useful? What else might you want to carry with you in the winter? How else can you increase your heat and utilize your resources? An emergency stove, hot cocoa mix, and bone broth always make it into my day pack on a snowy day, and I’m always carrying a snack and an insulated bottle in case I need more sustenance than I anticipated. What would your ideal emergency shelter design be?
Thank you to Lefthand Outdoor Challenge and their students for hosting us!
