In FY 2000, the Environmental Geology and Mineral Resources Program implemented a new Maryland Geological Survey (MGS) policy to publish only digital geologic maps. Starting in FY 2001, funding from the STATEMAP part of the National Cooperative Geologic Mapping Program (NCGMP) increased the MGS’s ability to produce digital geologic maps, clear a backlog of unpublished quadrangle maps and undertake new geologic mapping.

Rationales for choosing quadrangles for new geologic mapping include providing basic geologic framework analysis that provides the structural and stratigraphic data needed for hydrogeologic and mineral resource assessment studies, mine restoration, power generation station siting, water quality assessments, shoreline erosion, karst terrain studies and other geohazard mapping. Geologic quadrangle mapping also provides information about the physical environment that the plants and animals within Maryland’s watersheds depend on, and can provide historic and current information that assists local and state planning agencies, and also help shed light on current issues such as sea level rise and global warming.

From FY 2001 through 2003, STATEMAP supported production of digital geologic maps of the following previously mapped, but unpublished quadrangles: Davis, Table Rock, Barton, and Westernport quadrangles in Western Maryland; Hancock, Cherry Run, and Big Pool quadrangles in the Valley and Ridge Province; Indian Head and Benedict quadrangles in the Coastal Plain of Southern Maryland. In FY 03 STATEMAP also supported production of a revised digital version of the 1978 USGS geologic map of the New Windsor quadrangle in Central Maryland. In FY 04 STATEMAP supported the revision and digitization of the geologic map of the Middletown quadrangle map in western Frederick County, and in FY 05, the digital preparation of a revised version of the geologic map of the Union Bridge quadrangle in Frederick and Carroll Counties.

From FY 02 through the FY 07 STATEMAP funds were also used for new geologic mapping of Coastal Plain quadrangles on the upper part of Maryland’s Eastern Shore in Cecil, Kent and Queen Anne’s Counties. Quadrangles mapped as part of this effort are Earleville and the eastern part of Spesutie in FY 02 and FY 03, Cecilton in FY04, Galena in FY05, and Millington in FY06. In FY07, STATEMAP funding is supporting mapping of the Chestertown quadrangle. Mapping of these quadrangles will be used to produce a revised regional map of the surface and subsurface geology of Maryland’s upper Eastern Shore.  Also in FY08 STATEMAP funds are being used to support the revision and production of a digital bedrock and surficial geologic maps of the Myersville quadrangle in Frederick and Washington Counties, Maryland.
