What is the Geothermal Information Layer, release 2, for Oregon?

With the GTILO-2 web map you can view information on location, temperature, and other features of thermal springs and wells (geothermal exploration, geothermal test, and water wells) as well as direct-use areas. GTILO-2 data are currently accessible as ArcGIS Viewer for Flex interactive map data, Excel spreadsheets, compressed (zipped) .shp files including metadata, and PDFs.

Geothermal features are included for informational purposes only and should not be used to infer acceptable or permitted land use actions. Interested parties should contact their local land use authority to verify zoning and applicable land use ordinances. Respect the rights of private property owners. Understand that recreation in or around geothermal features is extremely dangerous and can result in serious injury or death. Stay out and stay alive!
