Grant Kohrs Ranch National Historic Site preserves a significant legacy of the open-range cattle era, situated along the banks of the Clark Fork north of the main settlement. The town of Deer Lodge serves as a civic hub, centered on its Courthouse, Post Office, and a notable Prison Museum. This mid-1990s landscape is defined by the convergence of several waterways, including Fred Burr Creek and Peterson Creek, which meet the river in a valley characterized by irrigation ditches like the O'Neil Ditch and the grazing lands of the ranching frontier.
