How and when should I purchase 10th Mountain’s topographic maps?

10th Mountain produces hut and season-specific topographic maps made of tear-proof paper. These maps are mailed from our office in Aspen, so it’s necessary to purchase them in advance of your trip. They can be purchased as part of the online booking process, over the phone, or from the 10th Mountain Store. These maps are also sold at a variety of outdoor retailers in Colorado including many REI stores (call ahead to see if the map you want is in stock).
