2017 Map of Willis Buttes

About this map

Willis Buttes rise above a landscape defined by an extensive system of drainages and reservoirs in McCone County. This 2017 survey shows a network of water resources vital for land management, including Jays Reservoir, Goose Island Reservoir, and Hell Gate Reservoir. The terrain is marked by significant navigational points such as Twitchell Pass and Lions Pass, while named peaks like Lytle Hill and Vanderhoof Hill provide distinct vertical relief. The hydrological pattern is centered on Shade Cr and its various branches, such as N Prong Shade Cr and S Fork Shade Cr, illustrating how water is collected and moved through this portion of eastern Montana. Isolated springs, including Rooney Spring and Horsford Spring, appear as critical point-sources of water in the higher elevations near Big Butte.
