This portion of the data release presents topographic Global Navigation Satellite System (GNSS) measurements acquired during the UAS survey of the debris flow at South Fork Campground in Sequoia National Park. The data contain the locations of the temporary ground control points (GCPs) used for the structure-from-motion (SfM) processing, as well as topographic measurements collected using a backpack-mounted GNSS rover. For the GCPs, 23 temporary points consisting of a combination of small square tarps with black-and-white cross patterns and "X" marks placed on the ground using temporary chalk were distributed throughout the survey area. For each GCP measurement the GPS receiver was placed on a fixed-height tripod and set to occupy the GCP for a minimum occupation time of one minute. For the topographic data acquisition, a GNSS rover was mounted to a backpack and used to collect continuous 1-second data on bare-ground surfaces of the debris flow site that were accessible on foot. The GNSS measurements were made using a real-time kinematic (RTK) GPS, with corrections from a GPS base station located on a temporary benchmark ("SFKW") established on the foot of the debris flow. The approximate base station position was initially derived using an autonomous position. The final coordinates for SFKW were derived using a seven-hour static occupation, submitted to the National Geodetic Survey Online User Positioning Service (OPUS-S). The resulting OPUS solution conforms to the quality standards for a USGS Level II single-base survey. After the survey was completed, the RTK data were adjusted using the final SFKW position using the Trimble Business Center software package. The GNSS data are presented in a comma-delimited text file.

This data release contains field data for two P-wave seismic reflection profiles acquired across the Warm Springs Valley fault zone, part of the Northern Walker Lane, NV. The dataset consists of high-resolution seismic reflection field records in .segy format, shot coordinates in .csv format, and observers’ logs in .pdf format. The high-resolution seismic profiles are approximately 4 km long. The northern profile (Warm Springs Line 1) is oblique to a prominent fault bounded ridge. The southern profile (Warm Springs Line 2) crosses the northern end of Warm Springs Valley and is nearly co-located with COCORP profile NV-08. To obtain the seismic profiles, we used a 230-kg accelerated weight drop source and a nominal geophone spacing of 5 m. We deployed single 8 Hz vertical‐component geophones and recorded data on 168 of these sensors per field record. Source stations were co-located with the geophone stations.

Text files: These data are text files of GNSS survey points collected along a trace of the West Napa Fault Zone near Ehlers Lane north of St. Helena, California. Data were collected to aid in paleoseismic investigation of the suspected fault strand and to characterize local geomorphology. Data were collected on March 31, and August 1, 2017 using a Leica Viva GS15 survey-grade GNSS receiver. The data are delivered as positions in the NAD83 UTM zone 10N coordinate system with orthometric heights according to Geoid 12B. LAZ files: These data are point clouds from terrestrial lidar data collected along a trace of the West Napa Fault Zone near Ehlers Lane north of St. Helena, California. Data were collected to aid in paleoseismic investigation of the suspected fault strand and to characterize local geomorphology. Point cloud data were collected on March 31, and August 1, 2017. The data were collected prior to trench excavation along a north-trending elongate rounded hill within Napa Valley, thought to represent the northern trace of the West Napa Fault, and then concurrent with trench excavation, overlapping and extending 200 m to the southwest of the first data set, to better characterize local fluvial history. Data were collected with a Riegl VZ400 terrestrial laser scanner and georeferenced using a Leica Viva GS15 survey-grade GNSS receiver. The data are delivered as georeferenced (NAD83 UTM zone 10N orthometric) classified point clouds. Raster Data: These data are 10-cm GeoTiff rasters of ground elevations from terrestrial lidar data collected along a trace of the West Napa Fault Zone near Ehlers Lane north of St. Helena, California.

A rockfall occurred between the night of January 5 and the morning of January 6, 2025 on the Point Bonita Trail in the National Park Service Golden Gate National Recreation Area, California. The rockfall originated from a granodiorite rock face in the Franciscan Formation and deposited approximately 25 cubic meters of rock on the pedestrian trail below. The U.S. Geological Survey collected three three-dimensional point cloud models of the rockfall and surrounding terrain using GPS and terrestrial LIDAR instruments. The three surveys were performed at various distances and angles from the rockfall to best capture its dimensions given limited access on the surrounding trail.

This lidar dataset was collected for William Krugh at California State University, Bakersfield as part of the Center for Climate and Natural Resource Solutions for Water-limited Regions project. This project is part of NSF's Center for Research Excellence in Science and Technology (CREST) program. Roughly 252 km2 of data were collected over the Kern River Canyon east of Bakersfield, CA.

This dataset, located within Joshua Tree National Park, CA, was collected as an NCALM Seed grant for Katherine Anna Guns, University of Arizona, Geosciences Department to support an investigation of possible slip rates on the Southern San Andreas Fault through the Eastern Transverse Ranges. The requested survey area is located approximately 31 km east of Palm Springs, CA. The polygon encloses approximately 64 km2. Note: A considerable percentage of the points in this dataset were classified as "building" (LAS class 6) although visual inspection indicates these points are mostly above-ground vegetation. For the purposes of distribution through OpenTopography, these points have been grouped with "unclassified" (LAS class 1) points to reduce point cloud classification to either "ground" or "unclassified" below.

This data is associated with the Nevada Play Fairway project and contains the entire package of LiDAR data for Granite Springs Valley.

This data release contains point clouds obtained from three terrestrial laser scanner (TLS) surveys of a hillslope (NAD 83/11 N/ 412828E/ 3780128N) burned by the 2016 Fish Fire in the San Gabriel Mountains, CA, USA. The TLS surveys were completed with a Leica ScanStation C10. The first survey was made on 19 November 2016 prior to the first post-wildfire rainstorm. The second survey was performed on 5 January 2017. Two runoff-generating rainstorms occurred between the first and second surveys. The two rainstorms had peak fifteen-minute average rainfall intensities of 27 mm/h and 10 mm/h, respectively. The third survey was performed on 22 February 2017, following five additional runoff-generating post-wildfire rainstorms. Peak fifteen-minute average rainfall intensities for the five rainstorms were 8 mm/h, 11 mm/h, 16 mm/h, 25 mm/h, and 38 mm/h, respectively. Maps of hillslope erosion derived from the TLS data can be used to document hillslope erosion resulting from these two sets of rainstorms, including the initiation and growth of a substantial rill network. Additional details and a description of the study site can be found in the journal article: Hui T, McGuire LA, Rengers FR, Kean JW, Staley DM, Smith JB. Evolution of debris flow initiation mechanisms and sediment sources during a sequence of post-wildfire rainstorms. Journal of Geophysical Research. 2018.

In summer 2021, the Bureau of Land Management - Nevada (BLM NV) requested that the U.S. Geological Survey Mineral Resources Program (USGS MRP), acting through the Geology, Minerals, Energy, and Geophysics Science Center (GMEGSC) and other collaborating USGS Science Centers, conduct a scoping study to: 1) discover mineral resource data and relevant publications that have been released since the publication of the 2016 USGS Sagebrush Focal Area Mineral Resource Assessment (SaMiRA; Day and others, 2016) for the Nevada portion of the Focal Area, and 2) evaluate whether these data support an update to the assessment for the SFA lands in Nevada. The commodities of interest for this scoping study are: copper, gold, lead, lithium, molybdenum, silver, tungsten, vanadium, zinc, and rare earth elements (REEs). This report is being released as a restricted file federal interagency report (RFFIR). This data release comprises the geospatial files used in the post-2016 assessment. It includes a point shapefile of exploration sites (SaMiRAII_exploration_sites.shp), a point shapefile of reanalyzed NURE geochemical data (SaMiRAII_NURE_reanalyzed.shp), four polygon shapefiles of mine claims and plans and notices for the purpose of plotting density (SaMiRAII_mill_sites_counts.shp, SaMiRAII_placer_claims_counts.shp, SaMiRAII_plans_notices_counts.shp, SaMiRAII_lode_claims_counts.shp), a polygon shapefile of mine claims (SaMiRAII_mine_claims.shp), and a polygon shapefile of plans and notices (SaMiRAII_plans_notices.shp). The SaMiRAII_mine_claims.shp and SaMiRAII_plans_notices.shp shapefiles contain overlapping polygons due to the fact that multiple claims can reside in a single section or quarter section.
