Right: Rock glaciers are very common alpine landforms in southcentral Montana as shown here. Each maroon triangle represents an individual rock glacier.
The state's highest mountains are the Beartooths (Beartooth Plateau) southwest of Billings, and Big Sky Resort is in the Madison Range south of Bozeman. Rock glaciers are also common in mountain ranges in Europe, South America, New Zealand, Canada, Alaska . . . and the list goes on! They are simply often overlooked because they are camouflaged by their rocky covering, i.e., their talus mantle. (NOTE: 40 km = 24.8 miles)
