The Upper Delaware Scenic and Recreational River stretches along approximately 73.4 miles of the Delaware River from Hancock, New York to Sparrowbush, New York on the border between New York and Pennsylvania. It includes parts of five counties along this section of the river: Delaware County, Orange County, and Sullivan County in New York and Pike County and Wayne County in Pennsylvania.
The site includes and protects Roebling's Delaware Aqueduct and the Zane Grey Museum. The Zane Grey Museum sustained significant damage due to the Eastern United States flooding of June 2006. Most of the land in this unit of the National Park System is privately owned, the federal government owns only approximately 30 acres. Within the park are the remains of the Delaware and Hudson Canal. This canal operated from 1828 to 1898 carrying anthracite coal and other regional products to the Hudson River where the products were shipped to various markets including New York City. The Delaware and Hudson Canal Company is considered one of the first private million dollar companies in the United States. Some of the remains of the canal are a National Historic Landmark.
