About: Bear Pond Mountains

The Bear Pond Mountains are a sub-range in the Appalachian Mountains, that straddle Pennsylvania and Maryland in the United States. These mountains are a part of the Ridge and Valley Appalachians and reach their highest point at Cross Mountain (Pennsylvania) 2,062 feet (628 m). A unique geologic feature known as the "Punchbowl" occurs in this range. This feature was created by the weathered shales of the Ordovician age in the center of a south-plunging anticline, having been eroded to expose a large amphitheater-like feature (punchbowl). Cross and Hearthstone Mountain are made of hard resistant quartzite of the Tuscarora Formation of the Silurian age, which form the walls of the bowl.
