About this map

Yellowstone National Park dominates this high-elevation landscape in northern Wyoming, where the Lamar River carves through its eponymous Lamar Canyon. The map reveals a complex network of glacial and volcanic terrain, stretching from the expansive Buffalo Plateau in the north to the iconic Grand Canyon of the Yellowstone in the southwest corner. The confluence of several significant watercourses, including Slough Creek and Crystal Cr, defines the drainage patterns of the Lamar Valley.

Historic transit corridors are well-documented, featuring the NE Entrance Rd alongside primitive backcountry routes such as the Soldier's Trail and Specimen Ridge Trail. Rising between these drainages are the heights of the Absaroka Range and Specimen Ridge, while the northern margin marks the boundary where the park meets the Montana state line. The concentration of water sources like Jasper Cr and Amethyst Cr suggests the geological diversity of this protected wilderness.
