Hydraulic test data
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 rel
Hydrologic monitoring data
Boreholes were drilled in 2017 and 2018 in Redwell Basin, a headwater catchment underlain by hydrothermally altered sedimentary rock in the Elk Mountains near the town of Crested Butte, Colorado. Two boreholes were completed as vertically discrete nested monitoring wells (MW1 as MW1A-MW1D and MW2.1
