 The park is in the West Branch Pine Creek drainage basin, where the underlying rocks are primarily conglomerate, sandstone, and shale.Two major rock formations are present in Cherry Springs State Park, both at least partly from the Carboniferous period.The youngest of these, which forms the highest points in the park, is the early Pennsylvanian Pottsville Formation, a gray conglomerate that may contain sandstone, siltstone, and shale, as well as anthracite coal.
