PA Department of Environmental ProtectionThe DMO Industrial Mineral Mined Out Areas (MOA) dataset identifies the areas of various noncoal industrial minerals in Pennsylvania that have been extracted by various underground mining techniques. The information in this dataset was gathered from digitizing the area of extracted non-coal industrial minerals identified on historic and modern mine maps. The maps to these mines are stored at many various public and private locations throughout the Commonwealth. The maps have been scanned to create a digital archive, and georeferenced to their approximate location for use in a geographic information system (GIS). The dataset is continuously updated as new maps are processed.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/1e574aa755034f1688dbec3ca4af0793_0engPennsylvania Department of Environmental ProtectionPublicDMO Mined Out Area Industrial Minerals Underground (MOA) [Pennsylvania]Web servicesPennsylvaniaLast Modified: 2026-01-08
