Bathymetric lidar data from the Blue River and Colorado River, near Kremmling, Colorado, October 18, 2018
The U.S. Geological Survey contracted with Juniper Unmanned to conduct field tests of the ASTRALiTe bathymetric lidar system on the Blue River and Colorado River near Kremmling, Colorado, on October 18, 2018. The objective of this project was to assess the potential to map river bathymetry (i.e., channel bed topography) using lidar data collected from an unmanned aircraft system (UAS). The ASTRALiTe lidar instrument was mounted on a DJI Matrice 600 Pro UAS owned and operated by Juniper Unmanned. As part of the study, Juniper's pilot flew the ASTRALiTe instrument across 2 river transects (cross-stream) on the Blue River and 2 river transects (cross-stream) on the Colorado River. This data release includes data delivered...
This data release includes data delivered to the USGS by ASTRALite in October 31, 2019 and includes points collected in 6 separate acquisitions or 'voyages". The data for each acquisition are in *.txt format. The files includes points with horizontal positions, elevations that area classified as water surface elevations (coded as 41) and bottom surface elevations (coded as 40).
Data for three-dimensional distribution of groundwater residence time metrics in the glaciated United States using metamodels trained on general numerical simulation models
Residence time distribution (RTD) is a critically important characteristic of groundwater flow systems; however, it cannot be measured directly. RTD can be inferred from tracer data with analytical models (few parameters) or with numerical models (many parameters). The second approach permits more variation in system properties but is used less frequently than the first because large-scale numerical models can be resource intensive. With the data and computer codes in this data release users can (1) reconstruct and run 115 General Simulation Models (GSMs) of groundwater flow, (2) calculate groundwater age metrics at selected GSM cells, (3) train a boosted regression tree model using the provided data, (4) predict...
Layers of geospatial data include contours, boundaries, land cover, hydrography, roads, transportation, geographic names, structures, and other selected map features.

Unconformity between the Triassic Dinwoody Formation and basal conglomerate of the Lower Cretaceous Kootenai Formation. Beaverhead County, Montana. nd.
Album caption: Unconformity between the Triassic Dinwoody Formation and basal conglomerate of the Lower Cretaceous Kootenai Formation. Location is north of Trapper Creek Road just west of confluence of Sucker Creek, 20 m above road level. Hammer is on unconformity, and plane of hammer is parallel to contact. Angular discordance is about 15 degrees; pebbles of Kootenai conglomerate fill local depressions of the unconformable surface developed in the Dinwoody. Published as figure 13.

This item contains a data file (.csv) and associated metadata document (.xml) for the recalibration of the Sinking Pond hydrologic model. The hydrologic model was recalibrated using the R script ‘annotated_R_script_for_model_recalibration.R’ and the input dataset ‘Daily_values_for_climate_stage_and_model_terms.csv’ to produce recalibrated values for the four calibrated parameters in the model: KBR, KPR, KBG, and PG (see the ‘Entity and Attribute’ section of the metadata document ‘Model recalibration results including recalibrated parameters and model performance statistics.xml’ for parameter definitions; for additional information see table 9 in Wolfe and others, 2004). The data file ‘model_recalibration_results.csv’...
