Grasshopper Glacier, Ancient glacier in Beartooth Mountains, Montana.
The glacier covers an area of 320 acres at an elevation of 11,300 feet within the Absaroka-Beartooth Wilderness of Custer National Forest.
Geologist J.P. Kimball discovered the glacier in the early 1900s and sent frozen insect samples to the U.S. Bureau of Entomology for analysis.
Scientists study the glacier to learn about extinct species, including the Rocky Mountain locust, which disappeared at the start of the 20th century.
Access requires an off-road vehicle and several miles of hiking, with the road remaining closed approximately ten months each year.
The glacier contains millions of preserved grasshoppers frozen within its ice mass, creating a distinct elephant-skin appearance.
