The Virginia Department of Mines, Minerals, and Energy's interactive map shows the locations of abandoned coal mines throughout the state of Virginia. The map allows users to explore a range of mine features. These features are important because abandoned mines have many land-related problems such as landslides, stream sedimentation, hazardous structures, dangerous highwalls, subsidence, loss of water, acid mine drainage, and open mine portals.

The Maine Geological Survey's interactive map provides a range of mineral resource information for the state of Maine. The map allows users to explore Maine's significant mineral commodities, mineral deposits, selected historical mines, and more.

Much of the data can be downloaded for further use and analysis.

The Kentucky Geological Survey's interactive map provides scanned document information and location data related to Kentucky's mineral resources and their associated commodities; fluorite (fluorspar), galena (lead), sphalerite (zinc), barite, iron, nitrates, and phosphates. By clicking on individual points or regions of interest, users can access reports, drill-hole logs, cross-sections, field descriptions, lab analyses, maps, and legal information.

The interactive map also includes a 1:24,000-scale map of Kentucky's geology and faults.

The Missouri Geological Survey's Geosciences Technical Resource Assessment Tool (GeoSTRAT) makes a large amount of geoscience information available in interactive map form, including:

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
• Topographic maps and aerial imagery

The map allows users to select multiple layers that can be overlain on each other. By doing this, users can see how different features are related.

The Ohio Department of Natural Resources' Mines of Ohio map is a joint product of the Division of Mineral Resources and the Division of Geological Survey. The interactive map provides the locations and types of active mining operations for coal and industrial minerals across the state of Ohio. Also shown are surface affected areas, their reclamation status, and abandoned underground mines.
