| 説明 | Joints are fractures in rocks along which no differential displacement has occurred. This distinguishes them from faults, along which displacement has taken place.At water level in the photo are Devonian sedimentary rocks having a rectangular jointing pattern. The watercourse is the Genesee River, which has eroded a spectacular deep gorge in western New York State. The valley is often nicknamed "The Grand Canyon of the East".Locality: view from Inspiration Point, Letchworth State Park, Genesee Gorge, Wyoming County-Livingston County boundary, western New York State, USA |
