The Reef Package is a sequence of coarse-grained cumulates that host the J-M Reef Pd-Pt deposit in the Stillwater Complex of Montana. The top of the Reef Package marks the top of economic-grade platinum-group element mineralization and is identified by a distinct change in rock fabric, from the coarse-grained rocks of the Reef Package to finer-grained cumulates in the hanging wall. This dataset ta

This dataset comprises repeat surveys of field-saturated hydraulic conductivity and sorptivity following the October 2017 Nuns and Tubbs wildfires as part of an effort to document soil-hydraulic recovery. A summary table includes associated physiographic properties for each site, including: pre-burn vegetation, lithology, soil burn severity, location, soil texture, and associated van Genuchten par

This database contains the results of slip tendency and dilation tendency analysis of Quaternary faults in the Great Basin region, including parts of Arizona, California, Idaho, Nevada, Oregon, Utah, and Wyoming. This effort was undertaken to help identify faults and fault segments that are appropriately oriented to be stress-loaded for slip or to dilate under the ambient stress conditions. Both c

In this database, we compile and host several available onshore and offshore geologic, paleoseismic, geophysical, and instrumental datasets along the Cascadia subduction zone. The ScienceBase data release and downloadable map package is accompanied by an ArcGIS online map and StoryMap.

This data release provides access to an aeromagnetic survey over a part of northeastern California, an area that includes the city of Alturas, California. The survey extends across the Devils Garden part of the Modoc Plateau (west of the Warner Range) and westward to over Medicine Lake volcano. The survey covers the Likely fault zone, an enigmatic northwest-striking set of structures with possib

Arsenic (As) toxicity is a global environmental and health problem. There are both natural (eg volcanic activity) and anthropogenic sources of As (eg lead arsenate and copper arsenate were commonly used pesticides in the 1900's). Aqueous levels of arsenic in the Klamath Basin (CA, OR), which has a volcanic origin, can exceed at some locations both the Oregon Department of Environmental Quality hum

This data release includes information used to support the manuscript "Rockfall kinematics from massive rock cliffs: outlier boulders and flyrock from Whitney Portal, California rockfalls". The included datasets and supplement include data that was collected and processed to investigate the kinematics of boulder trajectories and impacts to both other boulders and to existing trees on the talus slo

This report summarizes the cosmogenic beryllium-10 (10Be) geochronologic results from boulders deposited on moraines in the Stura Valley of the Maritime Alps, the southwestern most extent of the European Alpine mountain chain, northwestern Italy. Within this report are detailed the methodologies used to collect samples of whole rock, determine the concentrations of cosmogenic 10Be in purified quar

These geospatial files are the essential components for the Geologic Map of the Stibnite Mining Area in Valley County, Idaho, which was published by the Idaho Geological Survey in 2022. Three main file types are in this dataset: geographic, geologic, and mining. Geographic files are map extent, lidar base, topographic contours, labels for contours, waterways, and roads. Geologic files are geologic

Images were collected using a remotely piloted unoccupied aerial system over the bluffs of the eastern shore of Lake Michigan in Miami Park rural residential area, Allegan County, MI. Images were collected on July 19, 2021, by Richard Becker, University of Toledo, and cover an extent between south of Lakestone Dr. to the north, and south of A St. to the south. Images were collected to monitor acti

Zircon grains separated from altered ash beds were analyzed to better understand the ages of the beds. Isotopic analyses for U-Pb geochronology and trace element geochemistry were performed simultaneously by secondary ion mass spectrometry using the Stanford-USGS SHRIMP-RG ion microprobe housed at Stanford University, USA. Analyses followed the analytical protocol and data acquisition conditions d

This data release supports interpretations of field-observed root distributions within a shallow landslide headscarp (CB1) located below Mettman Ridge within the Oregon Coast Range, approximately 15 km northeast of Coos Bay, Oregon, USA. (Schmidt_2021_CB1_topo_far.png and Schmidt_2021_CB1_topo_close.png). Root species, diameter (greater than or equal to 1 mm), general orientation relative to the s
