Grasshopper Glacier (Montana)

Grasshopper Glacier is in the Beartooth Mountains in Custer National Forest. The glacier is within the Absaroka-Beartooth Wilderness, a part of the Greater Yellowstone Ecosystem. This glacier was named for the tens of millions of locusts that have been found entombed in the ice, some for hundreds and perhaps thousands of years. Many of the grasshoppers are of species that now extinct, and the high level of preservation allowed early researchers to send some specimens to entomologists for identification.
