Description
This dataset contain raw data files in kmz files (Google Earth georeference format). These files include volcanic vent locations and age, the distribution of fine-grained lacustrine sediments (which act as both a seal and an insulating layer for hydrothermal fluids), and post-Miocene faults compiled from the Idaho Geological Survey, the USGS Quaternary Fault database, and unpublished mapping.
It also contains the Composite Common Risk Segment Map created during Phase 1 studies, as well as a file with locations of select deep wells used to interrogate the subsurface.

|---|---|---|---|
| American Falls Lake Seds Polygon.kmz | KML | Distribution of paleo-Lake American Falls lacustrine sediments. Distribution of American Falls lake sediments estimated from Desbrough et al 1989 (OFR89-0436), Phillips and Welhan 2006a,b (DWM-77 and DWM-78), and Trimble & Carr 1961. AF Lake Beds range from about 20 ft thick on margins to over 100 ft thick along the axis of the lake, which was approxximately parallel to current Snake River. | Open resource |
| CCRS.kmz | KML | Composite Common Risk Segment Map produced during Phase 1 studies. Derived from ArcGIS raster map compiled on 2 km grid scale. Represents the weighted sum of the Heat, Permeability, and Seal Common Risk Segment maps. | Open resource |
| Final SRP Faults Strain.kmz | KML | Compilation of post-Miocene faults in southern Idaho and surrounding region. Dataset evaluated for dilation tendency and slip tendency. | Open resource |
| Idaho Drill Sites - LatLon.kmz | KML | Locations of select deep drill hole sites used to interrogate the subsurface for lithologic control. | Open resource |
| Lake Burley Seds Polygon.kmz | KML | Distribution of lacustrine sediments deposited by paleo-Lake Burley. Based on water well logs from IDWR, compiled by Neal Farmer Wells show that ancient Lake Burley extended north just past the topographic scarp of lava flows from Kimama Butte, and east to just past upper end of current Lake Walcott. Sediments up to 750 feet thick just north of current Snake River, but typically 100-200 feet thick farther north, at depths of 200-300 feet below surface. | Open resource |
| Lake Terreton Paleo Mud Lake Seds Polygon.kmz | KML | Distribution of sediments from paleo Lake Terreton. Estimated from data in Anderson et al 1996 (OFR96-248) and Anderson et al 1997 (OFR97-4010). Sediment layers generally fairly thin, | Open resource |

| SRP Vents - Basalt.kmz | KML | Distribution of basaltic vents in the Snake River Plain and adjacent regions. Compiled by Shervais and Glen from a range of sources. | Open resource |
| SRP Vents - Rhyolite Domes.kmz | KML | Distribution of rhyolite domes and cryptodomes in the Snake River Plain. Compiled by Shervais and Glen from a range of sources. | Open resource |
| WSRP Lake Seds Polygon.kmz | KML | Distribution of lacustrine sediments deposited by paleo-Lake Idaho in the western Snake River Plain. Based on maximum extent of Pliocene/Pleistocene lake sediments, diatomites, shale, silt, +/- sandstone, ash layers. Includes algal reefs and oolite reefs. | Open resource |
