Summary

Boreholes were drilled in 2017 and 2018 in Redwell Basin, a headwater catchment underlain by mineralized and hydrothermally altered sedimentary rock in the Elk Mountains near the town of Crested Butte, Colorado. Site locations and drilling procedures are documented under the main page of this data release. Borehole geophysical data were collected in boreholes MW1, MW1UZ, and MW2.1 as open holes prior to well construction. Logging was performed by a combination of USGS and Mount Sopris Instruments (MW1) and University of Wyoming (MW1UZ and MW2.1) staff. Log types vary by well on the basis of available equipment, site limitations, and borehole conditions. In borehole MW1, log types include fluid temperature and conductivity, three-arm [...]

Purpose

The lack of high-elevation groundwater wells limits our understanding of the deeper (greater than 10s of meters) hydrogeology and geochemistry of mountain headwater catchments. These data were collected to provide direct observations of bedrock geologic and hydrologic conditions in a high-elevation headwater catchment and to advance our understanding of the role of bedrock groundwater in metal and nutrient fluxes to near surface environments.
