The clouds cleared last night, and we had a beautiful view of a moonlit Cotopaxi and a starry sky (with views of both the North Star and the Southern Cross) as we went to bed. After a restful night and a great breakfast at the hacienda Chilcabamba, we headed off into Cotopaxi National Park. An hour hike from the end off the road led us to the Cotopaxi climbers' hut--a spacious, clean, and comfortable hut at 16,000'. This afternoon we are resting, drinking hot tea, and getting used to the thin air at this altitude. Tomorrow we will hike to the glacier to review essential climbing skills before our summit attempt, which will begin with an alpine start tomorrow night.
