About this map

Picket Pin Mountain dominates this high-altitude landscape in Sweet Grass County, where the topography is defined by the headwaters of numerous waterways. The East Boulder River carves a path through the western portion of the map, fed by high basins and steep drainages like Canyon Creek and Brownlee Creek. This area illustrates a classic mountain hydrology, with glacial-fed water bodies such as North Picket Pin Lake and South Picket Pin Lake situated near the divide.

Evidence of historical land use and geological features appear in place names like Placer Basin and Iron Mountain, suggesting a legacy of mineral exploration and prospecting. The high-country terrain includes the expansive East Boulder Plateau and a series of named ravines, including Snowslide Gulch and Hubble Gulch, which indicate the environmental challenges of this corner of Montana. For the modern researcher, the map provides a precise record of the drainage patterns and peaks within the Gallatin National Forest area at the start of the 2010s.
