Remote Outpost: Camp 5 was suspended 3 meters above the San Agustin sump. Occupied for 11 days during 4 separate diving assaults on the sump it was the least comfortable camp in the cave. Just behind the camera a 10 m cascade thunders into the chamber with a monotonous, deafening roar. Sleeping was in hammocks suspended across the canyon by rock bolts. [photo ©1994 Bill Stone].
