2021 Map of Cook Peak

About this map

Yellowstone National Park terrain dominates this 2021 study of Park County, centering on the high elevations of the Washburn Range. The landscape is defined by a complex network of drainages including Lava Cr, Lupine Cr, and Blacktail Deer Cr, which flow from prominent summits like Cook Peak and Folsom Peak. These peaks form a central massif where the headwaters of the Gibbon River begin their descent. In the southern portion of the quadrangle, Grebe Lake serves as a major hydrological feature near the intersection of the Observation Peak Trl and Cascade Lake Trl. The map illustrates the remote character of this region, emphasizing the natural topography of Arrow Canyon and Observation Peak without modern road development, maintaining the wilderness character preserved within the park boundaries.
