Palisades Interstate Park in New Jersey is a 13.5-mile park that contains cliffs, talus slope, and riverfront along the Hudson River just north of the George Washington Bridge. It is an early example of interstate cooperation for land conservation in the United States. It was once the site of several stone quarries that threatened to destroy the Palisade Cliffs. In 1900, New York Governor Theodore Roosevelt and New Jersey Governor Foster Voorhees each signed bills to begin preserving the Palisades. In 1909, the site opened as a recreational park, and soon became a popular day trip destination for many New York City residents. Currently, the park is used for picnicking, hiking, fishing, cross-country skiing, cycling and boating.

Rock the Earth volunteers met on Sunday, April 24, to help tidy up the park. Rock the Earther’s collected debris from the rocks and beaches of the riverfront, and cleaned up litter in the picnic area and its surrounding woods. Rock the Earth’s regional coordinator, Kevin O’Donahue reported that the Rock the Earth volunteers felt the rewards of their efforts when several groups of park visitors & picnickers joined them in their work of cleaning up the park.
