Pisgah Mountain or Pisgah Ridge (on older USGS Maps) is a long ridgeline 12.5 miles (20.1 km) Tamaqua to Jim Thorpe (river gap to river gap) oriented NNE-to-SSW whose northside valley is followed by U.S. Route 209 from river gap to river gap. The ridge is a succession of peaks exceeding 1,440 feet (438.9 m) looming 300–540 feet above the towns of Lansford, Coaldale, Summit Hill, and Tamaqua in the Panther Creek valley. Near Summit Hill was the 'Sharpe Mountain' (peak), where in 1791 Phillip Ginter is documented as having discovered Anthracite leading to the formation of the Lehigh Coal Mine Company. In 1818 the Lehigh Coal Company took over the mines and the mining camp gradually became a settlement and grew into Summit Hill.
