Maryland's Geologic Features
Sideling Hill, Washington County
contact: Dale Shelton (dshelton@mgs.md.gov)
One of the best rock exposures in Maryland and indeed in the entire northeastern United States is located approximately 6 miles west of Hancock in Washington County, where Interstate 68 cuts through Sideling Hill. Almost 810 feet of strata in a tightly folded syncline are exposed in this road cut. Although other exposures may surpass Sideling Hill in either thickness of exposed strata or in quality of geologic structure, few can equal its combination of both. This exposure is an excellent outdoor classroom where students of geology can observe and examine various sedimentary rock types, structural features, and geomorphic relationships.
The Sideling Hill Exhibit Center, along Interstate Route 68 at the base of Sideling Hill, is managed by the Maryland Department of Natural Resources State Forest and Park Service, in cooperation with the Maryland Geological Survey, the Maryland Department of Transportation State Highway Administration, and the Maryland Department of Business and Economic Development Office of Tourism Development.
