  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.
