Jack Mountain is the 15th highest peak in the state of Washington and one of the giants of the Cascade Range. Easily visible from the Diablo Lake overlook on the North Cascades Highway, Jack is the highest peak that is seen along this scenic stretch of road that bisects through North Cascades National Park. This massive mountain is at a minimum a difficult class 4 climb on loose greenstone rock and steep gullies that ascend the south face. There are also more technical routes on the massif. Jack Mountain is named for Jack Rowley, a gold prospector in the area during the late 1800s who is credited with the initial gold find at Ruby Creek. Jack Mountain is situated in the Pasayten Wilderness east of Ross Lake and rises abruptly from its shores almost 7500 feet. Jack is the high point of the Pasayten Wilderness. The Nohokomeen Glacier is the largest glacier on the massif and it situated in a large cirque on the northwest side.
Refer to Fred Beckey's Cascade Alpine Guide, Climbing & High Routes, Volume 3, for complete information on all the established routes on Jack Mountain.
