The Upper Delaware Scenic and Recreational River stretches along approximately 73.4 miles (118.1 km) of the Delaware River from Hancock, New York, to Sparrowbush, New York. Most of the land in this unit of the National Park System is privately owned, the federal government owns only approximately 30 acres (12 ha). 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.
