The Delaware River's Uplands extend from the Catskill and Pocono mountains where it bubbles forth as cool mountain springs and trickling streams, to Hancock, NY where its East and West Branches meet to form the main stem, which flows down to the Delaware Water Gap where it enters the Piedmont section of the watershed.

The steep slopes of the Delaware watershed's Piedmont end abruptly at the Kittatiny Ridge, with the 3,000-4,000 foot peaks of the Pocono and Catskill Mountains giving way to the gently rolling hills and sweeping valleys of the Piedmont. The difference between the two regions is dramatically illustrated as the River spills through the Delaware Water Gap, a narrow opening in the Kittatiny Ridge. Similar geologic gaps occur in the Appalachian ridges as several Delaware tributaries enter the Piedmont.
