2020 Map of Plunket Lake

About this map

Mammoth Springs and Plunket Lake anchor this Broadwater County landscape, where the Missouri River valley's hydrological infrastructure meets the rising terrain of the Elkhorn foothills. The importance of water management in this arid stretch of Montana is visible through the Toston Canal, which winds along the eastern edge of the quadrangle. Local landmarks like the uniquely named Chewh-toowh-too-peh Hill provide distinctive topographic orientation for the region. The map details a network of named rural routes, including Lone Mountain Rd, Spikes Ln, and Buffalo Jump Rd, which trace the legacy of ranching and early land divisions. Natural drainage patterns are defined by Salt Gulch, Spring Cr, and the southward flow of Warm Springs Cr, illustrating the complex interplay between the valley floor and the surrounding mountain slopes.
