Jack Mountain is the 17th highest mountain in Washington state.[3] It is one of the 10 non-volcanic peaks in Washington State over 9,000 feet (2,700 m). It towers dramatically over the south end of Ross Lake, rising 7,450 ft (2,270 m) above the lakeshore in only 3 horizontal miles (4.8 km).[4] Nohokomeen Glacier nearly fills the cirque on the upper north slopes of the mountain.
