Welcome to the heart of North Cascades National Park. The Boston Basin area offers one of the best ski mountaineering playgrounds in the lower 48. With a vertical rise of over 6000 feet from the valley floor to the summits, the setting could not be more spectacular. The Quien Sabe Glacier is the perfect glacier for our curriculum, we can climb over Sharkfin Col and visit the impressive Boston Glacier, maybe summit Sahale Peak and camp in amazing scenery.  All in all, Forbidden Peak provides a perfect training ground to introduce you to the elements of ski mountaineering. 
We establish a base camp below the Quien Sabe Glacier on the first day. The rest of the time we will carry light day packs while exploring the terrain in the Boston Basin. Ski touring, ski mountaineering, glacier skiing, peak bagging, it is all there. This course is aimed at the back-country skier who is looking to take his or her skills to the high alpine environment. 
 
This course is also offered on Mount Baker, as a Splitboard Only course, and as an All-Women's Course on Baker.
