@ National Geographic Society 604 Spectators Take a Balcony Seat on the "Grand Canyon of the East" When glacial deposits ages ago diverted the Genesee River, its waters cut this spectacular gorge in beds of shale. Sculpture of the canyon continues even today. Buffalo philanthropist William Pryor Letchworth, who loved the defile, donated land to preserve it. Purchases and gifts have expanded the park to 13,348 acres.
