Going-to-the-Sun Mountain (9,647 ft) in Glacier National Park

Going-to-the-Sun Mountain towers over Glacier National Park with forested slopes and snow patches in a dramatic alpine valley.

From Logan Pass, Going-to-the-Sun Mountain rises in a jagged silhouette, its east face flecked with snow. That vertical drama encodes a tectonic ascent—the Lewis Overthrust pushed Precambrian rocks over younger layers, later sculpted by glaciers into the alpine skyline. The ascent to the summit is a strenuous hike with rockfall hazards; the landscape is a living record of deep time.
