Summary
Fig. 6. View looking up from Anvil Rock (immediately above D in Fig. 4) in main chamber of Devils Hole at about 80 ft (24.4 m) below water surface. The planar fissure strikes NE and dips 70–80 degrees to SE. Widths of the fissure typically range < 6.5 ft ( <2 m). White translucent mammillary calcite coats hanging wall (left in photo) of Paleozoic carbonate bedrock. Footwall (right in photo) is barely visible in the narrow fissure. Two U.S. Geological Survey research divers are at the pool surface. 1985. Additional information: Devils Hole Picture Story Principal investigator: Isaac J.

Description of Figures
All of the above-water and underwater figures (images), except Figure 4, were taken in and around Devils Hole by Ray J. Hoffman from 1984 to 1993, in support of U.S. Geological Survey research into paleoclimatology and aquifer geochemistry in cooperation with the National Park Service. Figures 13–26 were taken in an underground environment completely devoid of natural light.
