N Fork Blackfoot River cuts through this high-elevation terrain where the Lolo National Forest and Helena National Forest converge. This 2014 survey captures a landscape defined by significant topographic relief and a network of mountain drainages, including the headwaters of Cooney Cr and Theodore Cr. The map illustrates the complex boundary lines and public land survey system divisions within Lewis and Clark County, providing a clear record of the watershed patterns and land management zones at the time of the imagery. Researchers can trace the path of the river as it winds through the northern sections of the quadrangle, which remains largely characterized by its natural water features and lack of dense modern development.
