General Geospatial Data
Geospatial data is critical for all types of geothermal exploration. Early in the Utah FORGE project a number of geospatial datasets were produced for planning. This page contains links these data and maps.
- Utah Temperature Gradient Database This is a temperature gradient database for Utah, USA. It is located at the Utah Geological Survey. This contains data relevant to the Utah FORGE project.
- Temperature Contours This dataset contains several ArcGIS shapefiles, each with Temperature contour lines at different depths. Subsurface temperatures were important for characterizing the geothermal system beneath the FORGE site in Milford, Utah.
- Roosevelt Hot Springs Analytical Well-Based Temperature Model Data This submission contains a cumulative record of one-dimensional temperature modeling based off of well data in the vicinity of the Utah FORGE site. Temperature log data from wells used, and in some cases were extrapolated below the bottom of a number of wells. The data were corrected for elevation and location using the Utah FORGE earth model. All data are georeferenced to UTM, zone 12N, NAD 83, NAVD 88. These data locations correspond to well locations provided in GDR Submission 1111 (Well Data for Student Competition)
- Temperature Contours at 200 m The individual shapefiles in this dataset delineate estimated temperature contours (20, 40, 60, and 80 deg C) at a depth of 200 m in the Milford, Utah FORGE area. Contours were derived from 86 geothermal, gradient, and other wells drilled in the area since the mid-1970s with depths greater than 50 m. Conductive temperature profiles for wells less than 200 m were extrapolated to determine the temperature at the desired depth. Because 11 wells in the eastern section of the study area (in and around the Mineral Mountains) are at higher elevations compared to those closer to the center of the basin, temperature profiles were extrapolated to a constant elevation of 200 m below the 1830 m (6000 ft) a.s.l. datum (approximate elevation of alluvial fans at the base of the Mineral Mountains) to smooth the contours across the ridges and valleys.
- UGRC GIS Database for the State of Utah This is a link to the Utah Geospatial Resource Center (UGRC, formerly AGRC) that houses GIS data for the state of Utah. This includes geoscience, cadastre, elevation and terrain, digital aerial photography, roads, aquifer data, etc. Several GIS datasets used in the Utah FORGE project originated from this site.
- Faults, Fractures, and Lineaments in the Mineral Mountains This dataset includes a shapefile of the Opal Mound Fault, and multiple datasets of lineaments mapped in the Mineral Mountains which overlook the Utah FORGE site, hyperlinked to rose diagrams in a polygon grid shapefile.
- Heat Flow Contours and Well Data This dataset contains a shapefile of heat flow contour lines around the FORGE site located in Milford, Utah. The model was interpolated from data points in the Milford_wells shapefile. This heat flow model was interpolated from 66 data points using the kriging method in Geostatistical Analyst tool of ArcGIS. The resulting model was smoothed 100%. The well dataset contains 59 wells from various sources, with lat/long coordinates, temperature, quality, basement depth, and heat flow. This data was used to make models of the specific characteristics.
- Utah FORGE: Milford Site Location, Seismometer Locations, Basin Depth Models, and Potentiometric Contours This dataset includes the geographic extent shapefile of the Milford FORGE site located in Utah, along with a shapefile of seismometer positions throughout the area, and models of basin depth and potentiometric contours.
- Seismic and Other Shapefiles from the Roosevelt Hot Springs Area Three shapefiles in this submission show the position of proposed seismic line surveys. The mid-crustal velocity anomaly file shows the extent of an anomalously low P-wave velocity zone in the subsurface. Two other files show the extent of known hydrothermal systems in the Roosevelt Hot Springs area. Another file shows the location of the proposed water pipeline to pump water from the supply wells to the deep drill site.
- Area 0.5 m LiDAR Data During the Fall of 2016 AGRC and the Utah Geological Survey acquired ~205 square miles of 8 points per meter Quality Level 1 LiDAR of The Frontier Observatory for Research in Geothermal Energy (FORGE) area around Milford, Utah in Beaver and Millard Counties in western Utah. The 0.5 meter resolution bare earth DEMs and first-return/highest-hit DSMs in .img format have a 10.0cm vertical RMSE accuracy and are available for download. This elevation data was collected between October 26 and November 3, 2016 and has a UTM NAD83 (2011) zone 12 north meter NAVD88(GEOID12) projection.
- Geologic, Topographic, and Other Related Maps and GIS Data from the Earth Model This submission contains a number of maps and shapefiles related to the Utah FORGE site. Examples include geologic maps (several variations) and GIS data for the Utah FORGE site outline. All data are georeferenced to UTM, zone 12N, NAD 83, NAVD 88.
- Area Terrain Slope Data This archive contains a terrain slope image, in units of degrees, of the Utah FORGE area near Roosevelt Hot springs. The data was derived from 0.5 m resolution LiDAR DEM data and is in a GeoTiff format. It was processed using ArcGIS.
