Near-surface geophysical data collected along streams near Silverton, Colorado, USA (ver. 2.0, May 2022)

Near-surface geophysical data from within the Bonita Peak Mining District in Silverton, Colorado, USA are presented. These data were collected in 2019. 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 reach surveyed with FO-DTS and FDEM.
In 2021, an FO-DTS, FDEM, and magnetometer (MAG) dataset were collected along both banks of an approximate 3-4 km reach of the Animas River, spanning from Arrastra Gulch upstream to USGS gage 09358000.
