The U.S. Geological Survey's (USGS) Mineral Resources Program's interactive Geologic Map of U.S. States provides a large amount of information on geology, natural resources, and environmental data for every U.S. state, including:

• Surface and bedrock geology
• Mineral resources
• Geochemical and geophysical data
• Water monitoring sites
• Partial soil and land use data

All of the maps are also available as Google Earth files that can be downloaded and used on personal computers and mobile devices.

The National Oceanic and Atmospheric Administration's thermal springs map displays the location and temperature of thermal springs throughout the U.S. The hot springs shown on the map are color-coded based on recorded temperature (red = boiling, orange = hot, yellow = warm, black = information not available). Users can click on individual hot spring locations to find the hot spring name, location, and most recently recorded temperature.

The Washington Division of Geology and Earth Resources' interactive map of Washington provides a huge variety of information on the state's geology and natural resources, including:

The Virginia Department of Mines, Minerals, and Energy provides a large amount of information on Virginia's geology and natural resources in interactive map form, including:

• Surface geology
• Geothermal suitability
• Sinkholes
• Water wells
• Mineral resources and mining operations
