2017 Map of Alder Lake

About this map

Yellowstone National Park dominates this landscape, specifically the intricate shoreline where the South Arm and Southeast Arm of Yellowstone Lake meet. The map documents a strictly non-motorized backcountry environment, focused on the deep waters and the high elevations of Channel Mtn and Chicken Ridge. The interior is accessible primarily via a established network of paths, including the Trail Creek Trail and the Two Ocean Plateau Trail, which negotiate the marshy drainages of Chipmunk Cr and Grouse Cr. Islands like Peale Island and the Molly Islands sit isolated in the lake's expansive reaches. This survey provides a precise look at the drainage patterns around Alder Lake and the dramatic peninsula known as The Promontory, showcasing the preservation of this wilderness area in the early twenty-first century.
