Burton, B.L., Ball, L.B., and Minsley, B.J., 2022, Surface electrical resistivity tomography, magnetic, and gravity surveys in Redwell Basin and the greater East River watershed near Crested Butte, Colorado, 2017: U.S. Geological Survey data release, https://doi.org/10.5066/P934HUCX.

Summary

Surface electrical resistivity tomography (ERT), time-domain electromagnetics (TEM), nuclear magnetic resonance (NMR), magnetics, and gravity data were acquired in 2016, 2017 and 2018 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 [...]

Purpose

These surface data were collected to contribute high-resolution information about subsurface geologic structure that were used to inform the location of planned groundwater monitoring wells and the hydrogeologic conceptual model of the basin.
