Log Data

Temperature, pressure, gamma, and caliper data were acquired by BRG personnel in 1999. These data are available for download below. Simply click on the link for the desired file. A data file will appear on the screen. Select "File" and "Save As" and the file will be downloaded to your computer.

If you prefer to download all data and related documentation, click on the "All Black Rock Documentation and Data" link. A single zip file will be downloaded to your computer. Several programs can be used to decompress the files. StuffIt is the most common on Macintosh, WinZip on PC, unzip on Unix machines (note: gunzip will not work in this case). Once uncompressed, the files can be easily opened and manipulated in programs such as Excel, Kaleidagraph, or Word.

Please be sure to download the logging notes if you select the individual file download option. This file contains information that should be read before using the data.
