The mountains extend about 95 miles (153 km) from east to west, to the south of the Tanana River Valley, west of the Nebesna River and northwest of Wrangell-St. Elias National Park and the Copper River, and cover an area of 6,313 square miles (16,350 km2).

[1] The highest point of the range is Mount Kimball,[2] at 10,300 feet (3,100 m).

It has been designated a National Wild and Scenic River since 1980.
