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.

Wildfire building destruction and exposure in the conterminous United States, 2002-2022 Wildfire building destruction and exposure in the conterminous United States, 2002-2022
Wildfires pose a major threat to human life and property, but there is limited information for assessing numbers or precise locations of building losses at a national scale. This geospatial dataset was developed to identify point locations of all buildings destroyed by or exposed to major wildfire disasters from 2002-2022. The data include all wildfire events in the conterminous United...
Geochronological Data for: Geologic Map of the Emporia Quadrangle, North Carolina Geochronological Data for: Geologic Map of the Emporia Quadrangle, North Carolina
The Emporia 1:100,000-scale quadrangle straddles the Tidewater Fall Line in southern Virginia and includes a small part of northernmost North Carolina. Sediments of the coastal plain underlie the eastern three-fifths of this area. This data release contains geochronology from sediment samples collected in the eastern half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina...
Uranium-series geochemistry and geochronology of marine terrace corals, Perachora Peninsula, Greece and San Nicolas Island, California, USA Uranium-series geochemistry and geochronology of marine terrace corals, Perachora Peninsula, Greece and San Nicolas Island, California, USA
Emergent marine terraces record past periods of relatively high sea level and are common on uplifting coasts worldwide. Such landforms are extensive around the Gulf of Corinth area of Greece and along the coast of California, USA. In the Gulf of Corinth region, marine terraces record Quaternary uplift due to ongoing basin extension on the northern side of the Africa-Eurasia-Aegean Sea...
Micronesian Starling (Aplonis opaca) nesting data on Guam, 2015-2018 Micronesian Starling (Aplonis opaca) nesting data on Guam, 2015-2018
We designed and implemented snake-resistant nestboxes and tested their efficacy as a conservation tool by comparing nest survival in nestboxes to natural nests for Aplonis opaca (Såli, Micronesian Starling) on Guam. During 2016-2018, we monitored 340 nest attempts by 40 A. opaca pairs nesting in nestboxes and 53 attempts by 32 pairs nesting in natural nests (outside of nestboxes), for a...
Luminescence Data for Earthquake History of the Needles Fault, Arizona Luminescence Data for Earthquake History of the Needles Fault, Arizona
The following report summarizes the dating results from sedimentary deposits sampled by the USGS Geologic Harzards Team and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose...
Cosmogenic 10Be and 26Al Surface Exposure Data and Ages for Middle Pleistocene Terrace Deposits Along the Rio Grande, Sunshine Valley Sub-Basin, Southern San Luis Basin, Costilla County, New Mexico Cosmogenic 10Be and 26Al Surface Exposure Data and Ages for Middle Pleistocene Terrace Deposits Along the Rio Grande, Sunshine Valley Sub-Basin, Southern San Luis Basin, Costilla County, New Mexico
We provide new 10Be/26Al cosmogenic surface exposure ages for two samples collected from gravel terraces along the Rio Grande. Each sample consisted of approximately 6 milky quartz pebbles ranging in diameter from 3 to 5 cm collected from the surface of a pristine, unmodified middle Pleistocene terrace tread adjacent to fluvially scoured basaltic bedrock. Chemical isolation of aluminum...
Uranium and amino acid geochronology data for marine terraces around San Luis Obispo Bay, central California, USA Uranium and amino acid geochronology data for marine terraces around San Luis Obispo Bay, central California, USA
In the San Luis Obispo Bay area of central California, interpretations of marine terrace ages have been hampered by inconsistent results from geochronological indicators (U-series ages of corals and correlations using amino acid racemization of mollusks) and seemingly contradictory paleozoogeographic aspects of fossil faunal assemblages. The two lowest-elevation terraces are Q1 (lower)...
Surface and shallow subsurface thermal maturity data for the Arkoma basin, Ouachita Mountains, and Ozark dome region of the U.S.A. Surface and shallow subsurface thermal maturity data for the Arkoma basin, Ouachita Mountains, and Ozark dome region of the U.S.A.
Thermal maturity data (vitrinite reflectance (VRo)) data from the Arkoma basin, Ouachita Mountains, and Ozark dome region of the U.S. Data were originally collected in graduate student theses and dissertations, and in a research consortia ca. 1980-1990 under the advisement and leadership of David Houseknecht during his time at University of Missouri. Location data was originally in...
Cosmogenic Nuclide, Thermally Transferred Optically Stimulated Luminescence, and Paleomagnetic data from cave sediments from Fitton Cave, northern Arkansas Cosmogenic Nuclide, Thermally Transferred Optically Stimulated Luminescence, and Paleomagnetic data from cave sediments from Fitton Cave, northern Arkansas
This data release contains tabular data (comma-separated-value format) obtained for analyses of cosmogenic nuclides, thermally transferred optically stimulated luminescence, and paleomagnetism that were collected to constrain the age of sediments within Fitton Cave, Buffalo National River, north-central Arkansas.
Data on Lepidium draba seed set and genetic diversity in northern Colorado Data on Lepidium draba seed set and genetic diversity in northern Colorado
Data were collected on the seed production and genetic diversity of Lepidium draba, an invasive plant. Site characteristics were also measured for 26 sites throughout northern Colorado. In addition, a pollen supplementation experiment was conducted at six of those sites, in which L. draba plants were pollinated with within-population pollen, among-population pollen, or were not...
Raster layers of optimal protection and restoration sites, ecological status, greater sage-grouse lek abundance, and connectivity to prioritize multi-species, sagebrush ecosystem management across Wyoming, USA Raster layers of optimal protection and restoration sites, ecological status, greater sage-grouse lek abundance, and connectivity to prioritize multi-species, sagebrush ecosystem management across Wyoming, USA
This data release includes a set of 25 rasters representing solutions (and associated input data) to two sagebrush conservation problems that identify optimal sites across the state of Wyoming for protection or restoration action (based on management-relevant inputs and constraints). The arid sagebrush-steppe ecosystems of western North America are undergoing substantial loss and...
Argentine black and white tegu (Salvator merianae) morphometrics and gastrointestinal contents, Florida, 2016-2021 Argentine black and white tegu (Salvator merianae) morphometrics and gastrointestinal contents, Florida, 2016-2021
The dataset contains the gastrointestinal contents of 275 Argentine black and white tegus (Salvator merianae) collected between 2016 and 2021 from two geographically isolated populations in Florida: one in Miami-Dade County, established around 2011, and another in Charlotte County, established in 2018. Dietary analysis revealed a broad spectrum of consumed items, including vertebrates
