This U.S. Geological Survey (USGS) data release provides whole rock major, minor, and trace element geochemical data from the fluorine-rich Mount Emmons-Redwell porphyry molybdenum (Climax-type) deposit (Mt. Emmons-Redwell deposit), located approximately 5.6 km (3.5 mi) northwest of Crested Butte, Colorado. The Mt. Emmons-Redwell deposit partly underlies Redwell Basin on the northwest flank of Mount Emmons in the west-central region of the Colorado Mineral Belt. Mineralization of the Mt. Emmons-Redwell deposit occurs at depth as vein, veinlet, stockwork, and fracture-hosted Climax-type mineralization [308 Mt at 0.32% Mo (Galey, 1978; Guarnera and Anderson, 2007)], and is associated with the Mt. Emmons igneous complex....

This data release consists of 1,984 line-kilometers of airborne electromagnetic (AEM), magnetic data and radiometric data collected from October to November 2017 in the upper East River and surrounding watersheds in central Colorado. The U.S. Geological Survey contracted Geotech Ltd. to acquire these data as part of regional investigations into the geologic structure and hydrologic framework of the area. The AEM data have been inverted to produce a series of regional cross-sections that constrain the electrical properties of the subsurface to a depth of ~500m. Data were acquired using the VTEM ET time-domain helicopter-borne electromagnetic system along flight lines that cross important geological structures over...
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,...

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...

Surface electrical resistivity tomography, magnetic, and gravity surveys were conducted in July 2017 in the greater East River Watershed near Crested Butte Colorado with a focused effort in Redwell Basin as part of a broader study of the role of bedrock groundwater in the hydrogeology of mineralized mountain watersheds. Approximately ten kilometers of total field magnetics data were acquired on July 29, 2017 with a Geometrics G-858 cesium vapor magnetometer that detects changes in deep (tens of meters to kilometers) geologic structure based on variations in the magnetic properties of different formations. This data release includes the raw and processed magnetics data. They are provided as digital data, and 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...

The U.S. Geological Survey, along with scientists from Rutgers University, collected water chemistry, electromagnetic, redox-potential, dissolved oxygen, water flow rate, and water temperature data along stream and river corridors in multiple sub-watersheds of the East River Science Focus Area (SFA) near Crested Butte, CO. The concept of ‘river corridor’ science recognizes that the quality of flowing surface waters is intrinsically linked to their contributing catchments through hydrologic connectivity, including lower terrestrial hillslopes, floodplains, and riparian zones. Bidirectional river-floodplain exchange in particular can be critical to basin water storage and nutrient transformation dynamics, yet floodplain...

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...

Dataset includes the analysis results of 49 inorganic chemical elements bound to suspended-sediment particles below Paonia Reservoir during a sediment release in September 2017. Suspended-sediment samples were collected at U.S. Geological Survey (USGS) station number 385626107212000 by following data collection procedures and protocols in Edwards and Glysson (1999). The samples were freeze-dried after collection and then decomposed using a mixture of nitric, hydrofluoric, and perchloric acids. The dried residue after acid digestion was analyzed by atomic absorption spectrometry and inductively coupled plasma-mass spectrometry following procedures and protocols in Taggart (2002). Reference samples of flue gas desulfurization...

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 as MW2.1A-MW2.1C) and one borehole was completed as a single monitoring well (MW2 as RP8). Site locations and well construction are documented under the main page of this data release. Absolute (non-vented) pressure and temperature data loggers (PTDs) were deployed in these wells to monitor groundwater levels and fluid temperature over time. The period of record covers August 2018-September 2019 for all wells; the period...

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....
