The Oregon Department of Geology and Mineral Industries (DOGAMI) received American Recovery and Reinvestment Act of 2008 funding to compile all DOGAMI legacy geothermal information and make it available to the public and industry. The Volcanic Vents of Oregon (VVO-1) publication is part of that work. VVO-1 represents DOGAMI’s geospatial database of volcanic vent location information.

VVO-1 is provided in Microsoft® Excel® spreadsheet and Geographic Information System (GIS) geospatial formats. Data coverage is statewide in extent; the map displays locations for 2,747 sample records. Please read the Esri shapefile metadata.

Information regarding location, age, and rock composition of the volcanic vents is stored as attributes in the shapefile as well as in the spreadsheet. Locations of points are placed at the highest elevation of the vent feature.
