When I was researching the latest entry for my blog I learned that there are millions of mummified Rocky Mountain locusts in a glacier called (of course) Grasshopper Glacier which is in Custer National Forest, Montana, USA.
The Rocky Mountain locust is now extinct but during the 19th century there were swarms in the trillion that occupied a territory the size of New England and the mid-Atlantic states combined.
Imagine what a real life horror they were to the farmers who first settled the west.
There's more about this species on my blog
