Three Fingered Jack

Three Fingered Jack, named for its distinctive shape, is a Pleistocene volcano in the Cascade Range of Oregon. It is a deeply glaciated shield volcano and consists mainly of basaltic andesite lava.It was first climbed in 1923 by six boys from Bend, Oregon, or members of The Mazamas. Generally the rock quality is poor, although it is better closer to the summit. Jack isn't a very technical mountain, by the easiest route, but it offers stunning views of most of the cascade volcanoes to both the north and south. Usually once you break the treeline it is pretty windy, and most ascents are done from June through October.
