About this map

The Highwood Mountains rise sharply in this part of Chouteau County, creating a dramatic landscape where the plains of north-central Montana meet the high peaks. The topography is defined by prominent elevations such as Gossack Mtn and Harris Mtn, with numerous drainages like Dexter Creek and Keaster Creek carving through the mountain slopes. At the edge of the range, the Chouteau County Waterfowl Production Area surrounds Big Sag Lake, a vital wetland resource in an otherwise arid environment.

Local history is anchored by the small settlement of Highwood and the nearby Big Sag area. Genealogical interest is centered on the Upper Highwood Cem, located near the base of the mountains along South Gap Creek. The map details a network of rural roads and ranch lanes, including Swan Ranch Ln and Burley Hill Rd, which trace the path of early homesteading and modern agricultural operations in the shadow of the peaks.
