Geologically, the Pisgah Ridge divide is classed as of semi-major degree, the waters enter the same body, the Delaware, but do so over fifty miles apart as the north draining waters are feed waters of the Panther Creek running east as a Little Schuylkill tributary, whilst the eastern south slope waters drain into the valley formed by the Mauch Chunk Ridge paralleling Pisgah Ridge to the south, via the Mauch Chunk Creek Inspection today via maps.google.com shows the headwaters begin to flow east from ~ 0.5 miles (~2600 ft, estimated) south of Coaldale.
