Snake River Plain Geothermal Play Fairway Analysis - Phase 1 KMZ files American Falls Lake Seds Polygon.kmz

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fluids), and post-Miocene faults compiled from the Idaho Geological Survey, the USGS Quaternary Fault database, and unpublished mapping.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. 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.
