Microclimate observations associated with snowmelt experiment gradient sites, East River, Colorado, 2017 to 2020
The timing of snowmelt in mountain systems is a main driver of vegetation phenology and production, as well as recharge of soil moisture and ground water. Decreases in maximum snowpack and warmer spring temperatures have led to a higher frequency of early snowmelt. This study combines a natural elev
Sensor-based phenology from snowmelt experiment gradient, East River, Colorado, 2017 to 2020
The timing of snowmelt is a critical cue for the initiation of growth in mountain meadow ecosystems and can also impact the duration and magnitude of plant production. High frequency observations of species-level phenology are time consuming and require a high degree of expertise, and publicly avail

Geochemical characterization of floodplain sediments from Meander C and O in the East River Watershed, CO, USA.
This data package is part of the Watershed Function SFA data collection and contains geochemical characterization of sediments as a function of depth in the pumphouse vicinity, including Meander C and Meander O (oxbow). This data was used in the manuscript "Fox, P.M., Bill, M., Heckman, K., Conrad,
Predicting sedimentary bedrock subsurface weathering fronts and weathering rates: Dataset.
Although bedrock weathering strongly influences water quality and global carbon and nitrogen budgets, the weathering depths and rates within subsurface are not well understood nor predictable. Determination of both porewater chemistry and subsurface water flow are needed in order to develop more com
Geophysical borehole logging data of wells ER-GLS1, ER-GUM1, ER-PLM7, and ER-PLM8 at the East River Watershed, Colorado.
The purpose of this data set is to provide a means of characterizing the bedrock variability both within a single borehole location and across the East River Watershed. The East River is part of the Watershed Function Scientific Focus Area (WFSFA) located in the Upper Colorado River Basin, United St
Total Dissolved Nitrogen and Ammonia Data for the East River Watershed, Colorado (2015-2022)
This data package contains mean values for total dissolved nitrogen (TDN) and ammonia concentrations for water samples taken from the East River Watershed in Colorado. The East River is part of the Watershed Function Scientific Focus Area (WFSFA) located in the Upper Colorado River Basin, United Sta
Shale drilling field notes, lithologic descriptions, and core photographs of wells PLM5, PLM8, GUM1, and GLS1 at the East River Watershed, Colorado.
The purpose of this dataset is to maintain a record of the shale drilling field notes, lithologic descriptions, and core photographs taken at the PLM5 (Pumphouse Lower Montane Borehole #5), PLM8 (Pumphouse Lower Montane Borehole #8), GUM1 (Gothic Upper Montane Borehole #1), and GLS1 (GLS1 = Gothic L

Reactivation of a Cretaceous Thrust Surface by Basin-and-Range Extension, Southwestern Gunnison Plateau, Central Utah
Recent work in central Utah has outlined the broader features of the area's thrust geometry. Although individual interpretations differ, most models indicate the region is similar to better understood segments of the Cordilleran thrust belt. Poor and limited seismic data and the paucity of drill-hol

Reconnaissance geology of the Mississippian Leadville limestone and implications for mineralization controls, Fulford mining district, Eagle County, Colorado
Deserving of much appreciation are Russell K. Murphy, who assisted in navigating the rugged field terrain, and the E. C. Lorig family of Eagle, Colorado, whose friendship, generosity, and guidance were extremely valuable
Porosity Dependence of Deformation Bands In The Entrada Sandstone, La Plata County, Colorado
Close examination of zones of deformation bands in the Entrada Sandstone (Middle Jurassic) near Durango, Colorado suggests that the width of these vertical zones and the displacement across them is directly related to the porosity of the sandstone. Low porosity sandstone is less susceptible to fract
The organic geochemistry and water-rock system across a contact metamorphic profile in the Mancos shale near Crested Butte, Colorado
A Mid-Tertiary igneous intrusion into the Upper Cretaceous Mancos Shale provides an excellent natural laboratory to study the thermal effects of an intrusion on the organic geochemistry and water-rock system across a contact metamorphic profile. The intrusion, is believed to have established a high
