2019 Map of Isolation Peak

About this map

Rocky Mountain National Park dominates the northern reaches of this map, where the Continental Divide creates a high-altitude boundary between Grand and Boulder counties. This transition is marked by prominent summits such as Isolation Peak and Chiefs Head Peak, with the alpine environment punctuated by several significant water bodies including Spirit Lake, Thunder Lake, and Bluebird Lake. The terrain drops southward into the Arapaho National Forest and Roosevelt National Forest, where the complex drainage systems of the East Inlet and Roaring Fork define the landscape. A network of primitive routes like the Upper E Inlet Trail and the Lion Lake Junction - Thunder Lake Trail provide access through these high basins. The presence of the St Vrain Glacier and Moomaw Glacier near the crest highlights the perennial ice features that persist in these protected mountain corridors.
