looking at the North Fork of Cut Bank Creek below Mad Wolf and Bad Marriage Mountains. The North Fork of Cut Bank Creek ends and becomes just Cut Bank Creek at Starr School on the Blackfeet Reservation.

Cut Bank Creek is a tributary of the Marias River in the Missouri river basin watershed, approximately 75 mi long, in northwestern Montana in the United States, which having deeply eroded steep cliff banks anonymously gives name to the cut bank formal terrain term of geological science.

It rises in the Rocky Mountains in Glacier National Park at the continental divide and flows ENE onto the foothills and plains of the Blackfeet Indian Reservation, then southeast, past Cut Bank, Montana where it forms a scenic gorge 150 feet deep spanned by an elevated railway bridge just a mile from the town's Amtrak rail transport system passenger station and BNSF railway freight yards. The river and cliff there are prototypical giving rise to the eponymous formally named "cut bank" geographic terrain feature archetype.

In southeastern Glacier County, approximately 12 mi southeast of Cut Bank, it joins the Two Medicine River to form the Marias River.
