2019 Map of South Mamm Peak

About this map

Heiberger sits along the southern edge of this landscape where the high plateau country of western Colorado meets the valley drainage. The terrain is defined by a series of prominent peaks and gulches, including South Mamm Peak and Elk Mtn, which overlook a complex network of waterways like Buzzard Cr and Plateau Cr. This 2019 survey illustrates the overlapping administrative boundaries of the White River National Forest and the Grand Mesa National Forest, showing how the land is partitioned for conservation and public use. Significant elevation markers such as Windy Point and Spruce Point characterize the high-altitude environment, while numerous named gulches like Horse Gulch and Standup Gulch reveal the intricate erosion patterns of the region's geography. Modern infrastructure is represented by a grid of numbered roads, including 64 3/10 RD and Pennisula RD, providing access to the more remote sections of the forests and the area around The Peninsula.
