Forest fall colors, Letchworth State Park, Portageville, New York, USA.

Forest fall colors, Letchworth State Park, Portageville, New York, USA. The large park stretches 17 miles between Portageville and Mount Morris in the state of New York, USA. Drive or hike to many scenic viewpoints along the west side of the gorge. Geologic history: in the Devonian Period (360 to 420 million years ago), sediments from the ancestral Appalachian mountains eroded into an ancient inland sea and became the bedrock (mostly shales with some layers of limestone and sandstone plus marine fossils) now exposed in the gorge. Genesee River Gorge is very young, as it was cut after the last continental glacier diverted the river only 10,000 years ago. The native Seneca people were largely forced out after the American Revolutionary War, as they had been allies of the defeated British. Letchworth's huge campground has 270 generously-spaced electric sites.
