Well, that was our bivy "ledge." Based on my pack thermometer, it got down to 30F that night, but it still went by quick despite slimsy sleep. With all my clothes on, I wormed my lower half into my backpack--one time where I was glad I had that hurcan thing with me. It is still the only impromptu bivy I've had to experience. July 6, 2002.
