About This Attraction
Gunsight Mountain stands two peaks above Gunsight Lake, with Sperry Glacier gripping the northeast face. Exposed sedimentary strata run in visible layers along the cliff, catching light as you sweep the valley. The peak owes its ascent to the Lewis Overthrust around 170 million years ago, with glaciers finishing the rugged profile.
