Data
Staff of USGS Science Centers in Region 7: Upper Colorado Basin collect a wide variety of natural resource data types including spatial, geologic, hydrologic, and biologic. Data included in USGS-series publications that are not publicly available in USGS databases are published in Data Releases. Short descriptions and links to Data Releases produced by Region 7 Science Centers are shown below.

Community level traits of invaded plant communities in the United States Community level traits of invaded plant communities in the United States
Data were compiled from large trait databases for functional above and belowground traits (e.g. specific leaf area, specific root length, etc) of plants in communities across the United States along with information about the degree to which invasive species dominate those communities.
Digital database of the geologic map of the southern Stillwater Range, Nevada Digital database of the geologic map of the southern Stillwater Range, Nevada
This data set is a geospatial database for the 1:24,000 scale Geologic Map of the Southern Stillwater Range, Nevada (John and others, 2024). It contains all the geologic spatial information and text unit descriptions from the printed map, in the Geologic Map Schema (GeMS) format for digital geologic maps maintained by the USGS’ National Cooperative Geologic Mapping Program (NCMGP). Base...
Rates of change in invasive annual grass cover to inform potential management opportunities across the sagebrush biome of the western United States Rates of change in invasive annual grass cover to inform potential management opportunities across the sagebrush biome of the western United States
We used Rangeland Condition Monitoring Assessment and Projection (RCMAP) maps of annual herbaceous fractional components (mostly invasive annual grasses) to calculate mean rate of change in invasive annual grass cover over five-year time periods (ratesOfChange1987_2021.zip). We also created a map that identifies zones of the sagebrush biome that could be prioritized for different...
Annual burn severity mosaics for the southeastern United States (2000-2022) Annual burn severity mosaics for the southeastern United States (2000-2022)
The southeastern United States experiences frequent wild and prescribed fire activity. Mapped burn severity products in the southeastern U.S. face challenges accurately characterizing fire effects due to rapid post-fire recovery limiting observation windows, limited availability of cloud-free imagery, spectral confusion within wetland areas, and operational constraints. As mapped burn...
Fire records (levoglucosan, mannosan, and galactosan) recorded in the deep Denali, AK ice core from ~360 to 2013 CE Fire records (levoglucosan, mannosan, and galactosan) recorded in the deep Denali, AK ice core from ~360 to 2013 CE
Monosaccharide anhydrides (MAs), or anhydrosugars which include levoglucosan, mannosan, and galactosan are combustion products of cellulose and hemicellulose that are used as biomass burning tracers. These fire biomarkers are incorporated into smoke plumes, transported through the atmosphere, and return to the surface through wet and dry deposition that can be archived in ice cores. Here...
Physical and chemical data for dust deposited on Colorado Rocky Mountain snow cover during water year 2013 through water year 2016. Physical and chemical data for dust deposited on Colorado Rocky Mountain snow cover during water year 2013 through water year 2016.
Atmospheric particulate matter deposited to snow cover diminishes snow-surface albedo and results in early onset and rapid snow melting, challenging management of downstream water resources. We present here physical and chemical data from snow samples from 14 sites during the melt seasons of water years 2013-16 across 60,000 km2 of the central Rocky Mountains within the Upper Colorado...

Dendrochronological collections during the career of USGS emeritus, Paul Carrara: Douglas-fir (Pseudotsuga menziesii), Black cottonwood (Populus trichocarpa), Spruce (Picea), Shore pine (Pinus contorta contorta), Willow (Salix), Bristlecone pine (Pinus aristate), Engelmann spruce (Picea engelmannii), Aspen (Populus tremuloides), and Limber pine (Pinus flexilis) collections from western...
Zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA Zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA
This data release includes raw detrital zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA. Detrital zircon U-Pb data for five samples of metasedimentary rock (totaling 1459 zircon U-Pb dates) were acquired via laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) at the University of Arizona LaserChron Center. The...
High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, Utah from 2020-2023 High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, Utah from 2020-2023
The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et...
