Very large wrinkles (forming stairway in photograph) in schist in the northern part of the area. The main schistosity and the bedding strike north 60 degrees west and dip 50 degrees southwest (parallel to the crests of the wrinkles). A second schistosity is developed locally that strikes north 67 degrees east and dips 40 degrees northwest (parallel to the axial planes of the Wrinkles). The geologic pick rests on a sinuous quartz vein about 1 inch thick that follows the crenulations of wrinkles. The knobby character of the schist is caused by quartz-sillimanite knots. Custer County South Dakota. Published in U. S. Geological Survey Bulletin 1142-E. 1963.

This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (HUC12) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic...

This data release (version 2.0, July 2021) consists of a Microsoft® Access database that contains groundwater withdrawal estimates from 1913 to 2016 for the Death Valley regional groundwater flow system (DVRFS). The four tables in the database also are provided as individual comma-separated values (CSV) files. This version (2.0) of the data release contains the most current version of the database and supersedes all previous versions. A total of about 41,000 acre-ft of groundwater were withdrawn from DVRFS in 2016 of which 51 percent was used for irrigation, 20 percent for domestic, and 27 percent for public supply, commercial, and mining activities. The total groundwater withdrawals for Pahrump Valley (hydrographic...
The 2018 eruption from the lower East Rift Zone of Kīlauea volcano, on the Island of Hawaiʻi, was one of the most significant and destructive events on the volcano in the past 200 years (Neal and others, 2019; Patrick and others, 2020; Anderson and others, 2023; Mulliken and others, 2024). Between May and September of that year, 24 fissures opened on the lower flank of the volcano, producing lava fountains and expansive lava flows that covered an area of 36 km2 (Neal and others, 2019; Zoeller and others, 2020). Effusion rates at the dominant vent, fissure 8, were often >100 m3 s-1, and the total eruptive volume is estimated at 0.9–1.4 km3 (Dietterich and others, 2021) making it one of the most voluminous effusive...
Note: this data release is currently being revised and is temporarily unavailable The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand for water need by delivering routine assessments of water supply and demand and an understanding of the natural and human factors affecting the balance between supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface water quantity, quality, and use. This data release contains Mann-Kendall monotonic trend analyses for 18 observed annual and monthly...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and Kennecott Exploration Company. The survey was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 34,041 line km of magnetic and radiometric data were acquired over an irregular-shaped area of 6178 km. Data were collected from a helicopter flown at a nominal terrain clearance of 100 meters (m) above topography along E-W flight lines spaced at 200 m intervals. Tie lines were flown...

The Landsat-based Irrigation Dataset (LANID) uses a random-forest machine-learning model with greenness and vegetative indices, climate data, and crop masks to identify irrigated crops (Xie and others, 2021, Xie and Lark, 2021). Separate western US and eastern US methods are used to train and validate the model. Annual LANID maps for 2018-20 were created using the same techniques in Xie and others, 2021, and Xie and Lark, 2021.

Post-fire shifts in vegetation composition will have broad ecological impacts. However, information characterizing post-fire recovery patterns and their drivers are lacking over large spatial extents. In this analysis we used Landsat imagery collected when snow cover (SCS) was present, in combination with growing season (GS) imagery, to distinguish evergreen vegetation from deciduous vegetation. We sought to (1) characterize patterns in the rate of post-fire, dual season Normalized Difference Vegetation Index (NDVI) across the region, (2) relate remotely sensed patterns to field-measured patterns of re-vegetation, and (3) identify seasonally-specific drivers of post-fire rates of NDVI recovery. Rates of post-fire...
