Wynn Mountain (8,409 feet (2,563 m)) is located in the Lewis Range of Glacier National Park, in the U.S. state of Montana.

The mountain is named for Frank B. Wynn, physician and scientist who was killed while attempting to climb nearby Mount Siyeh on July 27, 1927.

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