Angel Wing is a 7,430-foot (2,260-meter) elevation mountain summit located in the Lewis Range, of Glacier National Park in the U.S. state of Montana.

Topographic relief is significant as the north aspect rises nearly 2,500 feet (760 meters) above Grinnell Lake in one-half mile.

Precipitation runoff from the peak drains into Grinnell and Cataract Creeks, which are part of the St. Mary River drainage basin.

Like other mountains in Glacier National Park, Angel Wing is composed of sedimentary rock laid down during the Precambrian to Jurassic periods.

Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks 3 mi (4.8 km) thick, 50 miles (80 km) wide and 160 miles (260 km) long over younger rock of the cretaceous period.
