In , a "Forum on Geologic Mapping Applications in the Washington-Baltimore Urban Area" was jointly sponsored by the U.S. Geological Survey and the Maryland Geological Survey with assistance from the Virginia Division of Mineral Resources. Geologic map users and stakeholders from six States (Md., Va., , Del., Pa., N.C.) and the District of Columbia were present at the Forum on Geologic Mapping Applications in the Washington-Baltimore Urban Area.

The Washington West 30’ × 60’ quadrangle covers an area of approximately 4, square kilometers (1, square miles) in and west of the Washington, D.C., metropolitan area. The eastern part of the area is highly urbanized, and more rural areas to the west are rapidly being developed. The area lies entirely within the Chesapeake Bay drainage basin and mostly within the Potomac River. Pg. Baltimore gneiss. Geographically extended into Anna River area of Virginia, where it forms a well-defined belt on east side of area. West of gneiss is Wissahickon schist. Source: US geologic names lexicon (USGS Bull. , p. ). A copy of William Smith™s geologic map appears on page 6. Like Smith™s map or the one on the cover, a geologic map generally uses differently colored areas to show the geographic expanse of each of the different types of materials at the Earth™s surface. A geologic map provides essential and interesting information; however. Geologic Maps of Maryland: Baltimore County.

The National Geologic Map Database (NGMDB) is a congressionally mandated project led by the U.S. Geological Survey and Association of American State Geologists. The purpose is to build a national archive of maps and related data about geology, hazards, earth resources, geophysics, geochemistry, geochronology, paleontology, and marine geology.
