Just after the drilling was completed in July, 2004, the hole was sampled for suspension P-wave and S-wave velocities by GeoVision Geophysical Services. The resulting report can be found at Report_4438-01-1.pdf (2.3 mb). See UCLA_velocity.xls for an Excel spreadsheet of the data and App Note P-Smethod.pdf for a description of the logging technique.

A log of the borehole deviation from true vertical was made by Pacific Surveys in June, 2005 (DevLog-063005.xls). Note the large deviation at the bottom of hole.
