About this map

Big Timber sits at the confluence of the Yellowstone River and the Boulder River, serving as the civic anchor of the region with the Sweet Grass County Courthouse at its center. The town's grid is dense with named streets like McLeod St and Harris St, extending toward the Old Boulder Bridge and the Big Timber Airport. This survey reveals a landscape deeply defined by water management and ranching infrastructure, evidenced by the intricate network of irrigation channels such as the Electric Light Ditch, Post-Kellogg Ditch, and Mauland-Westervelt Ditch.

Beyond the town, the terrain transitions into broad expanses like Airport Flats and McKenzie Flats, while the southern reaches of the quadrangle become more dissected by coulees and gulches. Significant landmarks like Mountain View Cem and family-named features such as Beley Pond and Fyfe Coulee provide valuable touchpoints for local historians and genealogists tracking the development of these Montana plains.
