Letchworth State Park, now a century old, grew out of a generous donation made by William Pryor Letchworth to the State of New York. The park’s remarkable history reaches back as far as the last ice age. From the Portage Gorge to the mighty highbanks at Mount Morris, Letchworth State Park follows the flow of the Genesee River, exploring the natural and human events that have shaped this inspiring landscape. Drawing on historical images and regional folklore from the collections of the authors, the park, and various local sources, the reader is invited into the past of a park that has been called the Grand Canyon of the East.
