Hydrologic and geophysical data from high-elevation boreholes in Redwell Basin near Crested Butte, Colorado
Four boreholes (MW1, MW1UZ, MW2, MW2.1) were drilled in the fall of 2017 and summer of 2018 in upper Redwell Basin, a headwater catchment underlain by hydrothermally altered sedimentary rock in the Elk Mountains near the town of Crested Butte, Colorado. The boreholes were continuously cored using a wireline HQ-sized coring system and sample a combination of Quaternary-aged surficial colluvium and the Cretaceous-aged Mesaverde Formation. In-situ injection-based hydraulic tests were performed in MW1 and MW2 during drilling while advancing using a single-packer apparatus in tandem with an in-line flow meter and interval pressure monitoring. Borehole geophysical logging was performed in MW1, MW1UZ, and MW2.1 in the...
Environmental tracer data from surface water and groundwater samples collected in Redwell Basin near Crested Butte, Colorado, 2017-2019
This dataset contains environmental tracer data from surface water and groundwater samples collected by the U.S. Geological Survey in Redwell Basin, an alpine watershed in the Elk Mountains near the town of Crested Butte, Colorado. The basin is underlain by interbedded shale and sandstone that have been variably hydrothermally altered and silicified by local magmatic intrusions. Samples were collected from 2017 to 2019 from bedrock monitoring wells completed at multiple depths, shallow hand-installed piezometers and mini boreholes, springs, mine adits, and streams. The tracer data include stable isotopes of water (oxygen-18 and deuterium), tritium, dissolved noble gases (He, Ne, Ar, Kr, Xe, and helium-3/helium-4...
Digitized oil and gas pads in the Piceance Basin of Western Colorado in 2005 based on a sample from 2015 data
Digitization of a selection of oil and gas well pad sites in the Piceance region of Western Colorado. A random sample of 146 pad locations from the "Digitized Piceance Oil and Gas Pads of Western Colorado, 2015" were used to identify the locations digitized in this dataset. The 146 polygons spatially intersect polygons in the 2015 shape file, but are not completely contained within the 2015 polygons. Well pad sites were delineated using a modified version of the Rapid Land Cover Mapping protocol (Preston and Kim, 2016). The base imagery used to delineate boundaries is the 2005 National Agriculture Imagery Program (NAIP) imagery. Preston, Todd M, and Kevin Kim. 2016. “Land Cover Changes Associated with Recent Energy...
Digitization of oil and gas well pad sites in the Piceance region of Western Colorado. Well pad sites were delineated using a modified version of the Rapid Land Cover Mapping protocol (Preston and Kim, 2016). The base imagery used to delineate boundaries is the 2015 National Agriculture Imagery Program (NAIP) imagery. Well coordinate locations facilitating the targeting of well pad sites were downloaded from the Colorado Oil and Gas Conservation Commission (COGCC) in February 2016.
