Grasshopper Glacier (Montana)

Grasshopper Glacier is a glacier in the Beartooth Mountains, within the Absaroka-Beartooth Wilderness in Custer National Forest, Montana, part of the Greater Yellowstone Ecosystem. Roughly 0.20 miles long and 0.25 miles wide, it starts above 11,300 feet and has receded from a length of more than 5 miles since it was first studied in the early twentieth century; by 2007 it had separated into several smaller glaciers occupying distinct north facing cirques. The glacier takes its name from the tens of millions of grasshoppers, including specimens of the now extinct species Melanoplus spretus, found entombed and preserved in its ice for hundreds or thousands of years.
