One hundred years ago this month, less than a year after the Harriman gift of $1,000,000 and 10,000 acres was leveraged to raise an additional $4.5 million in private and state funds, the Palisades Interstate Park Commission began its purchase of the five quarries that were steadily eating away at the stately Hook Mountain ridge between Nyack and Haverstraw, New York.

The first quarry purchased belonged to the Manhattan Trap Rock Company. Its facilities, including the concrete power house used to crush the rock before being loaded onto barges from the wharf, were eventually dismantled or converted by the WPA to recreational facilities. The power house, a beautiful dutch colonial sandstone building that sits at the foot of the mountain, was transformed into a bath house when swimming in the Hudson was still permitted. This magnificent example of adaptive use is now experiencing a second wave of interest by the community as the anchor of Nyack Beach State Park.

The River Trail, one of the Hudson River Valley Greenway Trails, runs north from Nyack Beach for almost five miles. A magnet for runners, cyclists, bird watchers, fishermen, lovers, and artists, it is the only trail along the lower Hudson in New York that does not share its waterfront with a train line or highway. The Long Path parallels this trail high above atop the cliffs.
