Cucumber Run is formed by a fan of feeder branches spread out over four to six square mile within Stewart Township, PA area that coalesce into the main stream of water that flows nearly two miles before its confluence with the Youghiogheny River in Ohiopyle State Park, PA. The small area of drainage makes its water level extremely dependent on recent weather conditions. Cucumber Run's headwaters are at around 1900 feet in elevation, just south of Kentuck Knob, with a 700 foot descent to the Youghiogheny River where its confluence is about 1200 feet in elevation. After it meanders through a rustic picnic area Cucumber Run makes a 35 - 40 foot free fall plunge (Cucumber Falls) into a beautiful ravine just before draining into the Youghiogheny River.
