Jack Mountain, Mountain summit in North Cascades, USA
Jack Mountain is a summit in the North Cascades with an elevation of about 9,066 feet, characterized by steep rocky faces and glaciers along its northwestern ridge. The peak rises dramatically above Ross Lake and offers multiple approach routes depending on conditions and climber experience.
The mountain was named in 1859 after prospector Jack Rowley who worked in this region. The first recorded ascent took place in 1904 when surveyor E.C. Barnard reached the summit.
The mountain ranks as the 14th highest peak on the Bulger List, representing a significant achievement for mountaineers in Washington State's climbing community.
The terrain is only passable in summer or early fall when snow and ice melt and routes open up. Visitors can approach from North Cascades Highway or across Ross Lake, with both options requiring good preparation and awareness of local conditions.
The peak holds the Nohokomeen Glacier on its northwestern face with steep ice fields that rise between 45 and 55 degrees, offering one of the region's more technical climbing challenges. These frozen slopes change seasonally, making each ascent different from the last.
