Figure 9. Diagram showing the depth to basement in the two Middle Valley holes which were reinstrumented with CORKs. Basement (shaded) at Site 857 is defined as the top of a sill-sediment complex at 470 mbsf. Basement rises to 250 mbsf under Site 858 and is extrusive basalt (from Davis and Becker, 1994b). Lines and circles at the center of the hole represent the temperature string and the position of the thermistors (black circles).
