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.

National-scale dataset of strontium isotope compositions in environmental materials for the United States National-scale dataset of strontium isotope compositions in environmental materials for the United States
This database contains published strontium isotopic ratios (87Sr/86Sr) and associated sample collection data for strontium dissolved in environmental waters for the United States (conterminous, Hawaii, Alaska, and coastal seawater). Samples included in this version were collected and analyzed between 1963 to 2022.
Data Release of Geochemical, Geochronologic, and Isotopic Data for Proterozoic rocks from the Mountain Pass REE deposit and its host rocks, Arizona, California, and Nevada Data Release of Geochemical, Geochronologic, and Isotopic Data for Proterozoic rocks from the Mountain Pass REE deposit and its host rocks, Arizona, California, and Nevada
This U.S. Geological Survey (USGS) data release includes whole-rock major, trace, and rare earth element geochemical data, whole-rock and mineral Nd-Pb-Sr isotopic data collected by thermal ionization mass spectrometry (TIMS), and uranium-lead isotopic data collected by Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods that characterize the Mountain Pass Rare...
Data release for New evidence for eolian activity and mammoths on Santa Rosa Island prior to the Last Glacial Maximum Data release for New evidence for eolian activity and mammoths on Santa Rosa Island prior to the Last Glacial Maximum
Sea-level fluctuations due to the growth and decay of continental ice sheets of the Quaternary exert a strong influence on geologic processes along coastlines. The California Channel Islands are no exception to this, and many studies have been conducted that focus on the extremes of these glacial-interglacial cycles, such as the last glacial period (marine isotope stage [MIS] 2) and the...
Data Release for Timing and Abandonment of the Chemehuevi Formation: a Conspicuous Pleistocene Sedimentary Deposit of the Lower Colorado River Data Release for Timing and Abandonment of the Chemehuevi Formation: a Conspicuous Pleistocene Sedimentary Deposit of the Lower Colorado River
This data release contains data for the associated publication: Timing and Abandonment of the Chemehuevi Formation: a Conspicuous Pleistocene Sedimentary Deposit of the Lower Colorado River
Tiered spatial conservation prioritizations for sagebrush ecosystems in northwest Colorado Tiered spatial conservation prioritizations for sagebrush ecosystems in northwest Colorado
This data release includes the results (and some input data) of a spatial conservation prioritization intended to guide management of sagebrush ecosystems in northwest Colorado. Stemming the loss and degradation of sagebrush ecosystems requires science-based tools to balance diverse habitat requirements of species and guide management actions to where they are most likely to successfully...
LiDAR, natural color and thermal infrared data collected by uncrewed aircraft system (UAS) for mapping topography and stream temperature along the Vermilion River, Montana, August and October 2023 LiDAR, natural color and thermal infrared data collected by uncrewed aircraft system (UAS) for mapping topography and stream temperature along the Vermilion River, Montana, August and October 2023
The U.S. Geological Survey collected low-altitude airborne LiDAR, natural color and thermal infrared imagery via a multirotor, uncrewed aircraft system (UAS) along with Real Time Kinematic (RTK) GPS survey data along a section of the Vermilion River in Montana in August and October 2023. Natural color and thermal infrared imagery was collected in jpg and tiff format respectively and...
Data release for The ichnology of White Sands (New Mexico): linear traces and human footprints, evidence of transport technology? Data release for The ichnology of White Sands (New Mexico): linear traces and human footprints, evidence of transport technology?
This dataset lists the values of experiments with modern travois. The abstract of the associated interpretive product describing the findings at the site is as follows: A travois is crafted from one or more wooden poles and is one of the simplest pre-historic vehicles. Although these devices likely played vital roles in the lives of ancient peoples, they have low preservation potential...
Digital Database of a 3D Geological Model of the Denver Basin Digital Database of a 3D Geological Model of the Denver Basin
This digital database release contains elevation surfaces on 24 surfaces representing the tops of geological formations in the Denver Basin. These surfaces were exported as raster data from Leapfrog software, in which the model was constructed. Inputs to the model include well top data compiled from state agencies, formation contacts extracted from the Stage Geological Map Compilation...
Data Release for Luminescence: Neotectonic Mapping of Puerto Rico Data Release for Luminescence: Neotectonic Mapping of Puerto Rico
This report details the luminescence ages and characteristics of four (4) samples that were collected by Jessica Jobe and Rich Briggs of the USGS. These samples are from Holocene and Pleistocene sediments offset by a fault that is exposed in a road cut. The roadcut is in Puerto Rico at 18.003828 and -67.140249 with an elevation of 13.5 m. The sample depths from the modern surface varied...
Citations in Environmental Assessments Prepared by the Bureau of Land Management in Colorado from 2015-2019 Citations in Environmental Assessments Prepared by the Bureau of Land Management in Colorado from 2015-2019
These data support a study with the purpose of better understanding science and data use in Federal public lands decisions in the United States. To do this, we assessed the number, type, and age of documents cited in 70 Environmental Assessments (EAs) completed by the Bureau of Land Management (BLM) in Colorado from 2015-2019. We focused on the BLM, as they manage the largest area of...
Data to fit habitat suitability models at different invasion stages and their results to evaluate model decisions Data to fit habitat suitability models at different invasion stages and their results to evaluate model decisions
This is a dataset containing the input and output data used in the analysis of best practices of invasive plant species distribution modeling (Young et al. 2024). We developed habitat suitability models for 13 invasive plant species at a variety of geographic ranges and different invasion stages and modeling strategies to assess the impact of predictor quality, thinning resolution, and...
Riparian vegetation, topography, and sediment quality along the Lower Virgin River 2010-2021 (ver. 2.0, January 2025) Riparian vegetation, topography, and sediment quality along the Lower Virgin River 2010-2021 (ver. 2.0, January 2025)
