About this map

Highwood and the smaller settlement of Big Sag occupy a landscape defined by the transition from high plains into the northern foothills of the Highwood Mountains. This 2017 survey details a ranching and agricultural region where water is the primary architect of the terrain, carved by drainages such as Spring Coulee, Brown Coulee, and Big Sag Cr. Prominent peaks like Gossack Mtn and Harris Mtn rise above the drainage basins, providing significant landmarks for the local cattle and wheat operations.

Evidence of established community life is found along the southern reaches near the Upper Highwood Cem and the Highwood Creek Bridge. The map traces a network of rural routes, including Swan Ranch Ln and Upper Highwood Creek Rd, which connect isolated homesteads to the primary corridor of Highwood Rd. Small-scale water sources like Harris Spring and the seasonally fluctuating Big Sag Lake remain vital points of interest for land management and genealogy researchers tracing family tracts in Chouteau County.
