Byrne and Nimrod sit along the northern banks of the Clark Fork, marking a corridor of transportation and settlement in the early 21st century. This landscape is defined by its deep drainages and prominent peaks, including the elevation at Medicine Tree Hill and the northern heights of Mount Baldy. The map reveals a complex network of gulches—such as Tendoy, Genoa Gulch, and Van Curan Gulch—that feed into the river valley from the surrounding highlands. South of the river, Tyler Creek and Harvey Creek create intricate patterns through the terrain, passing landmarks like Tyler Point and Welch Gulch. A significant historical artery, the Mullan Rd, is noted in the northeastern corner, tracing the path of early territorial travel. The settlement at Chalet Bearmouth further illustrates the localized development focused along the primary valley through this part of Granite County.
