Fractured
Near the summit of Black Point (6959 ft.) is an area cracked with deep (30 - 50 Ft.) fissures. Thirteen thousand years ago this was a Volcano beneath a shallow ice age lake. The water levels dropped and the volcano became an island and then a peninsula. Parts of the sides of the fissures are covered with a layer of crystalline tufa (Thinolitic tufa). In the background are the Sierra Nevada Mountains and a portion of Mono lake can be seen. Mono county, California, U.S.A.
