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.

Hatchling Growth Experiment Dataset from Invasive Burmese Pythons Captured in 2015 in Southern Florida

This dataset contains information about 58 hatchling Burmese pythons collected in 2015 from an invasive population in southern Florida. These hatchlings were used in an experiment that assessed the effects of food availability, clutch, and sex on their growth in captivity. The hatchlings were collected as eggs from the nests of two wild pythons, assigned to High or Low feeding treatments, and thei

Body condition scores and foaling outcomes in 2021 for 18 mares at Sulphur herd management area, Utah treated with gonadotropin releasing hormone

These data present outcomes for monitoring of 18 mares at Sulphur herd management area, Utah. Data include Henneke body condition scores (BCS) and foaling success, measured by visual observations of mares during the 2021 breeding season (April to September 2021) to determine if mares had a foal at foot. Mares were treated with gonadotropin releasing hormone vaccine on September 2, 2020 and booster

Data on grasshopper composition in the Thunder Basin National Grassland, Wyoming, USA

Grasshopper biomass and species-level diversity was recorded at locations on and off prairie dog colonies in the Thunder Basin National Grassland, Wyoming, USA. Data were collected in order to record the association between grasshopper communities and prairie dog colonies.

Data release for Evidence of glacial activity during MIS 4 in the Rocky Mountains, Colorado, USA

The Ziegler Reservoir fossil site near Snowmass Village, Colorado (USA) provides a rare opportunity to examine environmental conditions in the Rocky Mountains during marine isotope stage (MIS) 4 (71-57 ka). Although recognized as a global-scale cold event, MIS 4 is typically absent from Rocky Mountain glacial chronologies because the geologic evidence was either covered or destroyed during the sub

National Geochemical Database on Ore Deposits: Legacy data

There is a growing demand for commodities (elements, compounds, minerals) used in today's advanced technologies. Critical minerals are usually found in ore deposits that are deemed vital to economic and national security. The National Geochemical Database on Ore Deposits: Legacy data (NGDOD) contains chemistry and geologic information for nearly 30,000 historic ore and ore-related rock samples fro

An updated X-ray diffractogram library of geologic materials

The X-ray diffraction (XRD) pattern library presented here is intended for qualitative or quantitative mineralogical analysis of geologic materials. The original collection of 169 reference diffractograms was released by Eberl (2003) as a part of RockJock, a USGS program for quantitative analysis of mineralogy, which included patterns of many of the major rock-forming minerals needed to analyze a

U-Pb age determinations of uraninite by electron microprobe analyses of ore samples from two solution-collapse breccia pipe uranium deposits, Grand Canyon region, northwest Arizona, USA

This data release compiles the electron microprobe spot analyses of U, Th, and Pb concentrations in uraninite (U oxide) particles, and corresponding calculated age determinations, measured in samples of ore from two uranium-copper breccia pipe ore bodies, the Canyon (Pinyon Plain) and Hack II deposits. The U-rich samples that were analyzed typify the deposits hosted by solution-collapse breccia pi

Data Release for Reconstructing paleohydrology in the northwest Great Basin since the last deglaciation using Paisley Caves fish remains (Oregon, U.S.A.)

This dataset includes tables of stratigraphic age-depth information for Paisley Caves 2 and 5, in Oregon U.S.A., along with tables of fish bone abundance and stable and strontium isotopic data for fish remains and geological samples from the study area surrounding the Paisley Caves.

Magnetotelluric sounding data in the Silverton Caldera complex, Colorado, 2018

This data release includes magnetotelluric (MT) sounding data collected in July 2018 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 22 sites along four profiles ranging from 3 to 6 kilo

Pb-Pb and U-Pb data of Proterozoic to Phanerozoic cassiterite deposits in Russia

Cassiterite (SnO2), a main ore mineral in tin deposits, was collected by multiple Russian geologists or obtained from museum collections in both the USA and Russia and dated at the U.S. Geological Survey. The dated samples represent four different mining districts spanning the entire country from the village of Pitkaranta in the west (31 degrees E Longitude) to the Merekskoe Deposit in the Russian

Second Iteration of Range Wide Lesser Prairie Chicken Lek Habitat Suitability in 2019, Predicted in Southern Great Plains

We developed a second iteration of habitat suitability models for Lesser Prairie Chicken leks, across their range. The first modeling iteration used lek data collected from 2002 to 2012, land cover data ranging from 2001 to 2013, and anthropogenic features from 2011. Our second iteration model used occurrence points from new lek surveys (2015 to 2019) and updated predictor layers to evaluate chang

Mean flea counts from prairie dogs and their burrows in Utah (2000), New Mexico (2010-2012), and Montana (2016, 2019)

Mean flea counts from prairie dogs and their burrows in Utah (2000), New Mexico (2010-2012), and Montana (2016, 2019). Prairie dogs were live-trapped, anesthetized with isoflurane, and combed thoroughly for 30 or 45 seconds to remove and count fleas. Prairie dogs were allowed to recover from anesthesia and released at their trapping locations. Randomly selected prairie dog burrows were swabbed for
