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 well construction are documented under the main page of this data release. Hydraulic data were acquired during drilling and on core samples to estimate the hydraulic properties of selected geologic materials. While advancing the drill stem, long-interval packer tests were conducted in MW1 and MW2 boreholes to measure in-situ formation permeability. The open borehole interval targeted for each hydraulic test was exposed by raising the drill stem about 10 m above the bottom of the hole. A single-bladder packer [...]

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.
