Formed 12,000 years ago by a catastrophic flood, Gadway Sandstone Pavement Barrens Preserve is by far the Conservancy's most interesting and unusual Adirondack preserve.
The area was formed when glacial till was scoured off the flatrock, resulting in the exposure of an expansive rippled "beach" of Potsdam sandstone.
Why We Work Here
Gadway Barrens represents an outstanding example of a sandstone pavement barren, a globally rare natural community found in fewer than 20 sites around the world.
What We Do
The Nature Conservancy has worked cooperatively with the Miner Institute and the State University of New York at Plattsburgh to conduct scientific research at this unique site.
