Hydrologic and geophysical data from high-elevation boreholes in Redwell Basin near Crested Butte, Colorado: Borehole geophysical 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 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 caliper, natural gamma, acoustic televiewer (ATV), full-waveform sonic (FWS), and heat-pulse flowmeter (HPF). In borehole MW2.1, log types include fluid temperature and conductivity, three-arm caliper, natural gamma, spectral gamma, ATV, optical televiewer (OTV), FWS, long/short normal resistivity, single-point resistance, self-potential, and nuclear magnetic resonance (NMR). OTV logs are provided for borehole MW1UZ.
Data are provided in log-ascii standard (LAS) formatted files; data are self-described within the header of each LAS file following the formatting guidelines established by the Canadian Well Logging Society (CWLS, 2017,2020).
