Event Type Walk/Hike Description The rocks were one of naturalist John Burroughs' favorite aspects of the Slabsides location, but even he did not realize that the rocks represented sediments eroded from a Himalayan-scale mountain range nearly 400 million years ago. Since they were deposited in a shallow sea, the sediments were repeatedly caught in continental collisions which bent them and stood them literally on end. As if that wasn't enough, they were most recently scraped clean by a mile-thick sheet of glacial ice which melted a mere 14,000 years ago. Join Vassar College professor of earth sciences Jeff Walker for hike to read the many stories in the rocks of the John Burroughs Nature Sanctuary. The trails are part of the Hudson River Valley Greenway Trail System. SPACE IS LIMITED. REGISTRATION REQUIRED. Sponsoring Organization John Burroughs Association
