Near Inspiration Point on the Grand Canyon of the Yellowstone’s North Rim, the Glacial Boulder is a granite erratic carried here by a glacier from the Beartooth Mountains. It is a brief roadside stop with a clear lesson in how far glaciers can move large rocks. Some travelers find the boulder itself unremarkable, so it makes most sense as part of a visit to Inspiration Point and the canyon rather than as a destination on its own.
How the boulder reached Yellowstone
The granite boulder was carried from the Beartooth Mountains, about 15 miles away, and deposited near Inspiration Point around 80,000 years ago. Rocks transported away from their original location by glaciers are called erratics.
The boulder gives a close, visible example of the scale of glacial movement. The nearby trailhead can be confusing, and parts of the route may be difficult to follow.
