Hike to sleep instead of hike to ride this time!
Two tired people in sleeping bags in a snow cave.
In February 2018 I participated in a special event by the Alpenverein Gebirgsverein. They held a 2 day workshop on how to safely spend the night outdoors in winter. We learned about different types of bivouacs, how to stay warm and energized and then spent the night in self-built bivvys. My accomodation of choice was a snow cave.
