A group of 4 of us are going to attempt a winter summit in mid-Feb. We are trying to decide where to make base camp, and we were wondering if anyone knows if the Hermit Lake Shelters are open during the winter months. If so, has anyone stayed in these shelters? What are the conditions, availability during the winter? We like the idea of being 2.4 miles towards Tuckerman's but wanted to know more info firsthand before making that decision. Any help would be greatly appreciated!!!
