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.

Laboratory-based optical measurements for surface water samples collected within the Fraser River in the Upper Colorado River Basin from September 2021 through September 2023 Laboratory-based optical measurements for surface water samples collected within the Fraser River in the Upper Colorado River Basin from September 2021 through September 2023
Optical spectra reported here are collected from 17 surface water sampling sites within the Fraser River, a headwaters drainage of the Upper Colorado River Basin in the central western United States. The sample collection was conducted as part of the partnership between the United States Geological Survey’s (USGS) Next Generation Water Observation System (NGWOS) and Proxies Project, in
Whole rock geochemistry for the Central Death Valley volcanic field, California (ver. 2.0, February 2026) Whole rock geochemistry for the Central Death Valley volcanic field, California (ver. 2.0, February 2026)
This U.S. Geological Survey (USGS) data release provides whole rock major, minor, and trace element geochemical data for Neogene rocks in the Central Death Valley volcanic field (CDVVF), California. Samples from the CDVVF were collected in order to constrain the temporal and compositional magmatic evolution of the area.
Geomorphic Model Archive, Kootenai River near Bonners Ferry, Idaho, 2011-2022, model archive Geomorphic Model Archive, Kootenai River near Bonners Ferry, Idaho, 2011-2022, model archive
Between 2011 and 2018, numerous restoration treatments were constructed in the Straight and Braided and Straight Reaches of the Kootenai River in northern Idaho as part of the Kootenai River Habitat Restoration Project. Led by the Kootenai Tribe of Idaho, the project aimed to address a range of anthropogenic impacts inhibiting natural recruitment of the critically endangered Kootenai...
Estimated current and future environmental suitability of pinyon and juniper tree species for 3 emission scenario pathways (SSP2-4.5, SSP3-7.0, SSP5-8.5) across the western North America Estimated current and future environmental suitability of pinyon and juniper tree species for 3 emission scenario pathways (SSP2-4.5, SSP3-7.0, SSP5-8.5) across the western North America
These data were compiled to provide gridded estimates of environmental suitability for pinyon-juniper species in western North America. These gridded suitability projections provide estimates of suitability under current climate conditions and future climate conditions and allow for visualization of suitability change across each species’ entire range. These data consist of gridded...
Geomorphic attributes of campsites adjacent to the Colorado River in Grand Canyon, AZ Geomorphic attributes of campsites adjacent to the Colorado River in Grand Canyon, AZ
This dataset represents 505 campsites along the Colorado River in Grand Canyon with associated debris flow probabilities calculated for approximately a 100-year period (Griffiths and others, 2004) and geomorphic attributes mapped by the U.S. Geological Survey, Southwest Biological Science Center, Grand Canyon Monitoring and Research Center (GCMRC) (Hadley and others, 2018). The campsite...
Debris flow probabilities of ungaged tributaries to the Colorado River in Grand Canyon, AZ Debris flow probabilities of ungaged tributaries to the Colorado River in Grand Canyon, AZ
This dataset represents 763 tributary canyons and/or watersheds adjacent to the Colorado River in Grand Canyon with associated debris flow probabilities from 2004. Also, these data include tributary canyon and/or watersheds to Glen Canyon and several smaller watersheds in Grand Canyon where debris flow data is currently unavailable. Historic probabilities of debris flow occurrence were...
