Type: Landscape. Habitat Description: hardwood forrest by a river. Natural History information: The Red Sandstone trail lies along the bank of the Racquet River, south of Potsdam. The trail goes between the Hannawa falls and Sugar Island, both of which are known for their dams. The river is the source of 27 hydroelectric plants. I like this photo because I think the rushing water, melting snow, and small buds beginning to appear, are hopeful signs that spring is on its way.
