About this map

Yellowstone Lake dominates the geography of this quadrangle, its deep fingers and bays defining the southern interior landscape. The prominent peninsula known as The Promontory extends from the north, creating a complex shoreline where the lake's South Arm and Southeast Arm converge. This 2012 survey illustrates a wilderness defined by its water systems and isolated island features, including Peale Island and the Molly Islands.

Drainage patterns are clearly visible through the courses of Chipmunk Cr and Grouse Cr, which feed into the lake from the south and east. Higher elevations are represented by landmarks such as Channel Mountain, while smaller bodies of water like Alder Lake are situated in the upland terrain. The lack of human infrastructure on the map emphasizes the preserved character of this high-altitude ecosystem, where topographic detail focuses on the natural intersection of peninsulas, mountain slopes, and aquatic habitats.
