⭐ Core Definition: Cut Bank Creek

The Cut Bank Creek is a tributary of the Marias River in the Missouri River basin watershed, approximately 75 mi (123 km) long, in northwestern Montana in the United States, which having deeply eroded steep cliff banks eponymously 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 (46 m) 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.

👉 Cut Bank Creek in the context of Blackfeet Nation

The Blackfeet Nation (Blackfoot: Aamsskáápipikani / ǎmssk̇ǎaṗiiṗiik̇ǔni, Pikuni / ṗiik̇ǔni), officially named the Blackfeet Tribe of the Blackfeet Indian Reservation of Montana, is a federally recognized tribe of Siksikaitsitapi people with an Indian reservation in Montana. Tribal members primarily belong to the Piegan Blackfeet (Ampskapi Piikani) band of the larger Blackfoot Confederacy that spans Canada and the United States.

The Blackfeet Indian Reservation is located east of Glacier National Park and borders the Canadian province of Alberta. Cut Bank Creek and Birch Creek form part of its eastern and southern borders. The reservation contains 3,000 square miles (7,800 km), twice the size of the national park and larger than the state of Delaware. It is located in parts of Glacier and Pondera counties.

Cut Bank Creek in the context of Cut bank

A cut bank, also known as a river cliff or river-cut cliff, is the outside bank of a curve (meander) in a water channel (stream), which is continually undergoing erosion. Cut banks are found in abundance along mature or meandering streams, they are located opposite the slip-off slope on the inside of the stream meander. They are shaped much like a small cliff, and are formed as the stream collides with the river bank. It is the opposite of a point bar, which is an area of deposition of material eroded upstream in a cut bank.

Typically, cut banks are steep and may be nearly vertical. Often, particularly during periods of high rainfall and higher-than average water levels, trees and poorly placed buildings can fall into the stream due to mass wasting events. Given enough time, the combination of erosion along cut banks and deposition along point bars can lead to the formation of an oxbow lake.
