Part of Hall of New York State Environment.
Triassic Red Sandstone Slab (from East Paterson, New Jersey), polished and striated by the moving ice sheet.
The striae, or parallel scratches, were scraped by rock fragments in the ice. The boulders, carried along by the ice, were found in the same locality.
