Surface electrical resistivity tomography, magnetic, and gravity surveys in Redwell Basin and the greater East River watershed near Crested Butte, Colorado, 2017
Surface electrical resistivity tomography (ERT), magnetics, and gravity data were acquired in July 2017 in the greater East River Watershed near Crested Butte Colorado with a focused effort in Redwell Basin. Five ERT profiles were acquired within Redwell Basin and Brush Creek to map geologic structure at depths up to 40 meters, depending on the subsurface resistivity, using the Advanced Geosciences, Inc. SuperSting R8 resistivity meter. Approximately ten kilometers of total field magnetics data were acquired with a Geometrics G-858 cesium vapor magnetometer that detects changes in deep (tens of meters to kilometers) geologic structure based on variations in the magnetic properties of different formations. Ten gravity stations were acquired with a LaCoste and Romberg G-model relative gravimeter to map density variations.
This data release includes raw data for all methods as well as processed and/or inverted resistivity or water content models. Digital data from all methods are provided, and data fields are defined in respective data dictionaries.
