  Normally, when you think of glaciers in the northern Rocky Mountains, you think of valley glaciers with
cirques, aretes, and terminal moraines.  You may have never even suspected that some of the glaciers
flowing off these mountains behaved like continental glaciers.  In the northern part of the Rockies in
Montana there is an area where glaciers flowed East from the base of the mountains for a distance of up
to 30 miles, leaving behind large linear scratches known as glacial striations.
