Granite Outcrops Along Highway 87, Black Hills National Forest
This landscape along Highway 87 in the Black Hills National Forest showcases the region's characteristic granite highlands, formed by the ancient Harney Peak granite formation. The rugged terrain features weathered rock outcrops interspersed with ponderosa pines, some clinging to crevices and others growing amidst fallen timber from past fires. The area is part of the scenic Needles Highway corridor in Custer State Park, South Dakota, known for its challenging grades and dramatic mountain light. This environment reflects the geological history and ongoing ecological processes of the Black Hills.
