Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Structure-from-Motion derived point clouds and orthomosaic images of reference sections of the Silurian units including the Rose Hill Formation, Keefer Sandstone, McKenzie Formation, Bloomsburg Formation, Williamsport Sandstone, Tonoloway Limestone, and t Structure-from-Motion derived point clouds and orthomosaic images of reference sections of the Silurian units including the Rose Hill Formation, Keefer Sandstone, McKenzie Formation, Bloomsburg Formation, Williamsport Sandstone, Tonoloway Limestone, and t
This dataset consists of Structure-from-Motion (SfM) - derived point clouds and highly detailed orthomosaic images of two exposures covering the the Rose Hill Formation, Keefer Sandstone, McKenzie Formation, Williamsport Sandstone, Bloomsburg Formation, Tonoloway Limestone, and the Keyser Limestone. For each railway exposure, two datasets are published: an orthomosaic raster image and a...
Georectified mosaics of historical aerial photographs of the Colorado River in Parker Valley, Arizona and California, acquired in 1930, 1938, and 1947 Georectified mosaics of historical aerial photographs of the Colorado River in Parker Valley, Arizona and California, acquired in 1930, 1938, and 1947
The products provided here include four georectified mosaics of historic aerial photographs for the Parker Valley region within western Arizona and southeastern California. There are three individual mosaics from 1930, 1938, and 1947 covering different geographic areas. The fourth georectified mosaic is a composite of the three and covers the entire area of interest. These datasets were...
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...
40Ar/39Ar geochronologic data for mafic and intermediate volcanic rocks in the vicinity of Henrys Fork caldera, Yellowstone Plateau volcanic field 40Ar/39Ar geochronologic data for mafic and intermediate volcanic rocks in the vicinity of Henrys Fork caldera, Yellowstone Plateau volcanic field
While the timing and composition of the Yellowstone Plateau volcanic field’s caldera-forming tuffs and rhyolite flows are well-characterized, the chronology of smaller-volume mafic eruptions is poorly known, thereby limiting our understanding of how mafic magmatism drives rhyolite volcanism, particularly Yellowstone’s large caldera-forming eruptions. To address this gap in knowledge, we...
Magnetic susceptibility and gamma ray spectrometry measurements in southwestern Montana, 2023-2024 Magnetic susceptibility and gamma ray spectrometry measurements in southwestern Montana, 2023-2024
This dataset includes rock magnetic susceptibility and gamma ray spectrometer measurements from 243 outcrops in southwest Montana during 2023-2024. The measurements were collected to understand the causative sources of airborne magnetic and radiometric survey anomalies in the Idaho-Montana porphyry belt. Sixteen magnetic susceptibility measurements were collected at each analyzed site...
A global database of porphyry copper deposits and prospects A global database of porphyry copper deposits and prospects
Porphyry copper deposits are the world's primary source of copper and can also host a variety of secondary commodities identified as critical by the U.S. Geological Survey (U.S. Geological Survey, 2022). These deposits occur primarily along convergent plate margins, and their metal association and geochemical characteristics are reflective of whether the deposit formed in continental...
