Jack Mountain, Mountain summit in North Cascades, USA
Jack Mountain rises 9,066 feet above sea level with steep rock faces, glaciers, and a prominent northwestern ridge that extends toward Ross Lake.
The mountain received its name from prospector Jack Rowley in 1859, with the first recorded ascent completed by topographer E.C. Barnard in 1904.
The mountain ranks as the 14th highest peak on the Bulger List, representing a significant achievement for mountaineers in Washington State's climbing community.
Climbers can access the mountain through Highway 20 at milepost 138 or take a water taxi across Ross Lake to reach different entry points.
The Nohokomeen Glacier covers the northwestern face, creating a 200-meter headwall with slopes between 45 and 55 degrees.
