Dusty Star Mountain (8,573 feet [2,613 m]) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.

Dusty Star Mountain is easily seen from the Going-to-the-Sun Road, and often photographed by tourists taking pictures of Wild Goose Island which lies in the western section of Saint Mary Lake.

[4] Like other mountains in Glacier National Park, it 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.
