2012 Map of Lamar Canyon

About this map

Lamar River and Slough Cr dominate this hydrological network within the Lamar Valley, where the confluence of these waterways shapes the high-elevation landscape. The topography is defined by the carved depths of Lamar Canyon, a prominent geological feature through which the river flows westward toward the Yellowstone River. This 2012 survey illustrates the seasonal and perennial drainage patterns of the region, featuring numerous named tributaries such as Buffalo Cr, Crystal Cr, and Jasper Cr. The only built structures indicated are the Slough Creek Patrol Cabins, positioned north of the river and east of McBride Lake. The absence of roads beyond a single highway corridor emphasizes the protected and undeveloped character of this mountain wilderness, which remains a critical corridor for watershed management and native ecology.
