This trip will make only one stop, the abandoned workings of the Mineral Hill Mine which is located on state land surrounding the Liberty Reservoir, Carroll County, Maryland. The mine is located approximately 40 miles north of Washington, D.C. in the Piedmont Province. The Piedmont consists of gently rolling hills with thick soil cover and few outcrops. As we leave Washington, D.C., we will travel mainly on the coastal Plain until we turn west-northwest on Rt. 32 (Figure 1). We will travel across the Towson terrain traversing the Clarksville gneiss dome and enter the Liberty Complex as we turn northward. Just before we stop, we will cross the bridge over the Morgan Run Arm of the Liberty Reservoir where the old mine road comes out onto Rt. 32. Parking is available on the right side of the road. If you will look across the water to the east on the right side of the bus, you will be able to see the tailings pile of the Mineral Hill Mine. |
