Rockland County, NY


Park at the parking area at the entrance to Lamont-Doherty Earth Observation Laboratory. This is not easy to do sometimes since a lot of people want to park here and the parking spaces are limited indeed. If no parking here you can go from north to south on the Long Path by parking at the southern end of Tallman State Park and follow the turgois blazes south.


Sneden Landing, in the village of Palisades, was the western terminal of the Dobbs Ferry. Robert Sneden owned property here in 1752. His wife, Mary (or Molly) Sneden (17091-1810) ran the ferry to the village of Dobbs Ferry in Westchester County. (Adams 1981:115)

An historical marker outside the Lamont-Doherty Earth Observation Laboratory says:

Skunk Hollow or "the mountain" was a free black community from 1806 to 1905. The first known deed belonged to Jack Earnest from Palisades. 1840 -- William Thompson, African Methodist Episcopal itinerant preacher bought Jack's house, built a church on his land, and became a resident preacher. Over 100 families were here including Brown, Oliver, Sisco, Thompson, William, and many others.

Former estate of Dr. John Torrey (after whom the Torrey Botanical Society in named). He lived here from 1854 to 1865. He was followed by financier Thomas Lamont. In 1953 Lamont's wife left the land to her sons, Corliss and Austin, to maintain the land as a natural area. In 1954 the Audubon Society was named the custodian of the property. In 1969 the land was deeded to the Nature Conservancy. In 1970 the land was leased to Columbia University for research and education. In 1977 the land was finally transferred to Columbia.


Long Path, North to South:

parking at south end of Tallman State Park;
walk along Route 9W south;
pass old service station ruins;
pass by Washington Squire Road that if you walked down would take you to Sneden's Landing;
at 135 Route 9W (labeled a private drive) turn left, walk a little ways toward the building, cross the drive and head right into the woods; the trail is on the old bed of the Erie railroad;
trail heads up hill and then downhill to a Phragmites australis marsh (giant reed grass marsh); come out at Lamont-Doherty Earth Observation Laboratory entrance. If you wanted to keep going south follow the turgois blazes into the woods near where the cars are parked in the parking area. The trails heads toward the State Line Lookout.
