Relaxing sleep. The mild climate inside the ice caves is very pleasant, even when there is no emergency. After giving away my sleeping tent to visitors from McMurdo station I put up my encampment inside the nearby “Hut cave”. The original plan was that a helicopter would pick me up the following morning for my final ride back to McMurdo station. To avoid waking up late I had put two alarm clocks on my “bedside table” - the caves are a place of eternal tranquillity. What I did not know at that time was that the helicopter would not be able to get to our camp in the following 4 days due to bad weather, unintentionally extending my stay in this rather unusual sleeping spot.
