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.

This dataset accompanies geologic map publication " Geologic and geophysical maps of the onshore parts of the Santa Maria and Point Conception 30' x 60' quadrangles, California "; U.S. Geological Survey Scientific Investigations Map 3473. Data presented here include the digital geologic map database, paleontological sample locations and descriptions, and point data sets from magnetic and...
Data release for Surficial Geology of the Northern San Luis Valley, Saguache, Fremont, Custer, Alamosa, Rio Grande, Conejos, and Costilla Counties, Colorado Data release for Surficial Geology of the Northern San Luis Valley, Saguache, Fremont, Custer, Alamosa, Rio Grande, Conejos, and Costilla Counties, Colorado
The San Luis Valley and associated underlying basin of south-central Colorado and north-central New Mexico is the largest structural and hydrologic basin of the Rio Grande Rift and fluvial system. The surrounding San Juan and Sangre de Cristo Mountains reveal evidence of widespread volcanism and transtensional tectonism beginning in the Oligocene and continuing to the present, as seen in...
Compilation of in situ and detrital zircon U-Pb ages for the Jurassic-Paleocene North American Cordillera (28-50 degrees north) Compilation of in situ and detrital zircon U-Pb ages for the Jurassic-Paleocene North American Cordillera (28-50 degrees north)
This document includes two suites of zircon U-Pb ages that help to characterize the magmatic and sedimentary history of the North American Cordillera between ~28 and 50 degrees north. The first dataset is a compilation of published zircon U-Pb ages of igneous rocks associated with the Mesozoic-Cenozoic North American Cordilleran arc. The compilation of igneous zircon data includes 1,492...
Preliminary detrital zircon data for Upper Cretaceous to Paleocene strata of the Crazy Mountains basin, Montana Preliminary detrital zircon data for Upper Cretaceous to Paleocene strata of the Crazy Mountains basin, Montana
This document includes sandstone provenance data for Upper Cretaceous to Paleocene strata preserved in the Crazy Mountains Basin of western Montana, USA. The dataset includes detrital zircon data for six samples from the Upper Cretaceous Hoppers Formation (1 sample), Upper Cretaceous Billman Creek Formation (1 sample), and Paleocene Fort Union Formation (4 samples). Detrital zircon data...
Feral horse tail tag deployment and retention data at Conger and Frisco Herd Management Areas, Utah, 2016-2020 Feral horse tail tag deployment and retention data at Conger and Frisco Herd Management Areas, Utah, 2016-2020
These data show details of time taken to fit tail tags on horses at Herd Management Areas in Utah and Nevada. We provide the time of day that individuals entered and exited a squeeze chute and the resulting duration of time they were in the squeeze to have the tag affixed (among other things) at BLM facilities, as well as the sex and age of the individual, and dates that tail tags were...
Data release for tracking rates of post-fire conifer regeneration distinct from deciduous vegetation recovery across the western U.S. Data release for tracking rates of post-fire conifer regeneration distinct from deciduous vegetation recovery across the western U.S.
Post-fire shifts in vegetation composition will have broad ecological impacts. However, information characterizing post-fire recovery patterns and their drivers are lacking over large spatial extents. In this analysis we used Landsat imagery collected when snow cover (SCS) was present, in combination with growing season (GS) imagery, to distinguish evergreen vegetation from deciduous...
Soil Biogeochemical Data from a Marine Terrace Soil Climo-Chronosequence Comparison Soil Biogeochemical Data from a Marine Terrace Soil Climo-Chronosequence Comparison
The storage and persistence of soil organic matter (SOM) is of critical importance to soil health, and to the terrestrial carbon cycle with implications for long-term climate change. To better understand the spatio-temporal controls on SOM, we have developed a new dataset spanning two previously described marine terrace soil chronosequences from northern, CA, USA: the Santa Cruz and the...
MODFLOW-LGR2 groundwater-flow model used to delineate transient areas contributing recharge and zones of contribution to selected wells in the upper Santa Fe Group Aquifer, southeastern Albuquerque, New Mexico MODFLOW-LGR2 groundwater-flow model used to delineate transient areas contributing recharge and zones of contribution to selected wells in the upper Santa Fe Group Aquifer, southeastern Albuquerque, New Mexico
A three-dimensional groundwater-flow model of a 73.2 square mile area in southeastern Albuquerque, New Mexico was designed and coupled to a regional (parent) model of the Middle Rio Grande Basin with the local-grid refinement numerical code MODFLOW-LGR2. This fine-gridded local (child) model was designed to simulate the response of the aquifer to pumping stresses and simulate advective...
Magnetotelluric sounding data in the Silverton Caldera complex, Colorado, 2019 Magnetotelluric sounding data in the Silverton Caldera complex, Colorado, 2019
This dataset includes magnetotelluric (MT) sounding data collected in July 2019 in the Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field, by the U.S. Geological Survey (USGS). Along with geologic mapping, airborne magnetics, airborne electromagnetics, and audiomagnetotellurics, the USGS collected MT data at 24 sites along five profiles ranging from 2 to 5
Data release for Assessing the Uncertainties in Climatic Estimates Based on Vegetation Assemblages: Examples from Modern Vegetation Assemblages in the American Southwest Data release for Assessing the Uncertainties in Climatic Estimates Based on Vegetation Assemblages: Examples from Modern Vegetation Assemblages in the American Southwest
This data release includes climatic variables and associated descriptive material created for the purpose of assessing uncertainties associated with climatic estimates based on vegetation assemblages (Thompson and others, 2021). The data are from the interior of the western United States, including all of Arizona, and portions of California, Colorado, Nevada, New Mexico, Texas, and Utah...
In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Winter Colony Count Analysis In Support of the U.S. Fish and Wildlife Service 3-Bat Species Status Assessment: Winter Colony Count Analysis
Through the North American Bat Monitoring Program, Bat Conservation International and U.S Geological Survey (USGS) provided technical and science support to assistance in U.S. Fish and Wildlife Service Species Status Assessment ("SSA") for the northern long-eared bat (Myotis septentrionalis), little brown bat (Myotis lucifugus), and tri-colored bat (Perimyotis subflavus).
