Figure 6. Approximately 50 per cent of the bedrock at 

 4900 feet was exposed. Pillow lava appears to be covered 

 with a thin mantle of off-white sediment that includes a 

 ubiquitous distribution of black pebbles. Crustal bedrock 

 that has undergone erosion appears in the right back- 

 ground. Maximum microrelief of rock pile in background 

 was about 4 feet. Water current was observed to be 

 toward the background. However, no ripple marks or 

 scouring are evident. The two white crescents to the 

 left and right of photograph center are photoprocessing 

 faults. Dive No. 60.
