Course
Beaver Creek rises in Bridgeton Township near Lonely Cottage Road at an elevation of approximately 540 feet (160 m) and runs generally southwest for 3.68 miles (5.92 km) until it meets its confluence at Tinicum Creek's 6.41 river mile at an elevation of 226 feet (69 m). During its course it receives three tributaries from the left and three from the right. The average slope is 85.3 feet per mile (15.37 meters per kilometer).[4]
Beaver Creek's course is located in a region of diabase rock which intruded into the local sedimentary layers of the Brunswick and Lockatong Formations during the Jurassic and the Triassic, then the remaining course flows over the Brunswick Formation. Diabase is a dark gray to black, fine grained and very dense, consisting of primarily labradorite and augite.[5]
