Red Buttes Hydrogeophysics Test Site

The Red Buttes Hydrogeophysics Test Site, owned by the University of Wyoming, is about 19 km south of Laramie, Wyoming. The geologic structure consists of three shallow-dipping, sub-horizontal layers in the near surface: an unconsolidated clay loam, the Satanka Formation, and the Epsilon Sandstone Member of the Casper Formation. The unsaturated 3-4 m thick clay loam is a low-resistivity layer that overlies the lower- resistivity silty-claystone of the Satanka Formation, found to 12 m depth. Finally, starting approximately 12 m below the surface is the consolidated Casper Formation Epsilon sandstone. The Epsilon sandstone is generally observed to have a much higher resistivity than the overburden.

This dataset contains a range of measurements acquired at the Test Site that may be useful for instrument calibration/validation, joint-measurements comparisons, and demonstration datasets.
