Yipes! It would be funny, if not a common mistake. I learned in arctic survival school that once bedded down to stay there. One student got lost and we were an hour finding him. I never did regain my body heat. later on excavations we devised a latrine system after yet another student went lost half the night. Designate a latrine area and deploy some chem lites from the camp to the latrine. Clean everything up before leaving.
