Summary

This dataset has been archived; it has been superseded by version 2.0 (May 2022) which can be found at https://doi.org/10.5066/P97HDPAY. Near-surface geophysical data from within the Bonita Peak Mining District in Silverton, Colorado, USA are presented. The data include fiber optic distributed temperature sensing (FO-DTS) and frequency domain electromagnetic induction (FDEM) data collected in and around roughly 1 km reaches of Cement Creek and California Gulch. Additional data, including ground penetrating radar (GPR) and self potential (SP), were gathered from a peatland that intercepts acid mine drainage from Mogul Mine into Cement Creek. The peatland is located off the eastern bank of Cement Creek in the northern portion of the [...]

Purpose

The Bonita Peak mining district, located near Silverton, CO, contains several abandoned mines and was designated a superfund site after the 2015 Gold King Mine waste water spill. Near-surface geophysical data were collected in this study primarily to ascertain likely groundwater discharge locations to streams and to gain insight regarding properties of the discharge (e.g., relative variations in electrical conductivity and magnetic susceptibility). These data support ongoing study of hydrological connectivity between the mines and surface water.
