Early studies of soil formation highlighted several key factors that together determine the degree of soil pedogenesis, which include climate, organisms (including vegetation), topography, and parent material (Jenny H.; 1941; Factors of Soil Formation, a System of Quantitative Pedology; https://doi.org/10.2134/agronj1941.00021962003300090016x). A soil chronosequence is defined as a series of soils

This dataset includes a line shapefile of surface traces that were calculated using structural measurements taken in the Stillwater Complex, Montana (Stillwater_Complex_Surface_Traces.shp), along with a .csv file of full references for the published sources used (Stillwater_SurfaceTrace_sources.csv). The surface traces represent the lateral extension of geologic features. The structural measuremen

The California Coast Range are an area with a long-lived deformation history which includes modern, ongoing right lateral strike slip faulting. Large strike slip faults in the region include the San Andreas fault, the Maacama fault, the Bartlett Springs fault among many others. In areas where strike slip fault geometry changes, either in restraining or releasing bends, vertical motion may occur in

A three-dimensional geologic map was created by assembling eight geologic cross sections derived from geologic mapping, potential field geophysics, and petroleum well logs. The central feature of the map is the San Andreas Fault, with many other prominent structural features depicted that express the regional transpressional tectonic setting. The subsurface interpretation was based on existing two

Micropaleontological data have provided essential stratigraphic age control for geologic investigations in the Cascadia forearc, such as the Coast Range-Olympic Mountains and Puget-Willamette Lowland west of the Cascade Range. Foraminiferal assemblages and, later, coccoliths (calcareous nanoplankton) have been the most abundant microfossils recovered from the Cenozoic sequence. The usefulness of c

Scoggins Dam in northwest Oregon lies within the Gales Creek fault zone (GCF), a northwest-striking system of active faults forming the boundary between the Coast Range and the Tualatin Valley about 25 km east of Portland, Oregon. Geologic mapping published in 2020 shows the dam to lie within a block-faulted releasing stepover between the right-lateral, NW-striking Scoggins Creek and Parsons Creek

This data release provides access to a low-altitude aeromagnetic survey flown over a part of the Cascade Range of the US Pacific Northwest, approximately centered over the town of Packwood, Washington. The Packwood magnetic survey surrounds but does not include the edifice of Mount Rainier, the highest (4392 m; 14,410 ft) volcano of the conterminous United States. Data were acquired between Septem

Projections of extreme event metrics and threshold exceedances are produced by analyzing the Climate Model Intercomparison Program Phase 6 Localized Constructed Analogs (CMIP6-LOCA2) data set. The primary daily temperature and precipitation data are summarized to 36 annual metrics and 4 monthly metrics. This data set includes output from 27 GCMs for the period 1950-2100 under ssp245, ssp370, and s

The text file in CSV (comma-separated values) format contains marine magnetic data from 291 cruises in the Northern Pacific Ocean and Bering Sea. These data originate from two sources: 266 cruises from the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI) Marine Trackline Geophysical Database (GEODAS) -- https://www.ncei.noaa.gov/access/me

The data herein are geochemical (from X-Ray fluorescence spectrometry), grain size (percent clay, silt, sand), lithological (loss on ignition data), bathymetric, reconstructed IVT, and radioactive isotopes (14-C, 210-Pb, 226-Ra, and 137-Cs). These data were collected from sediments from Leonard Lake, Mendocino County, California, USA starting in 2014. Together, these data provide evidence for a re

This data release presents point data associated with the geologic and geophysical maps of the Sierra Nevada Digital Earth Science Atlas led by the California Geological Survey and U.S. Geological Survey. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2012 to 2023 and for existing gravity measurements compiled from 21 sources. Near

On February 14th, 2019, a strong atmospheric river storm (AR4 on the Atmospheric River scale of Ralph et al., 2019) struck California. The heavy rainfall caused landslides in both northern and southern California (Hatchett et al., 2020). This data release includes two subsets of mapped shallow landslide source locations in the vicinity of western Riverside County, California, where sufficient post
