About this map

The Rimrocks formation dominates the central landscape of this Yellowstone County survey, creating a sharp topographical divide between the upland plateaus and the valley floor. In the mid-1950s, this area functioned as a critical corridor for transport and irrigation, evidenced by the parallel tracks of the Northern Pacific and Great Northern railroads. These rail lines follow the path of Canyon Creek, while a network of water management features like the Great Northern Ditch and Big Snow Ditch supported the local agricultural economy.

Small settlements and community landmarks are scattered throughout the region, including the rural Base Line Sch and the community of Rimrock. The map also captures early industrial activity with several labeled Oil Wells and a Well (Hot Water). Local infrastructure is further defined by established thoroughfares such as Grand Avenue and Central Avenue, which provide access to the drainages of North Fork Alkali Creek and South Fork Alkali Creek.
