About this map

Mosca Pass serves as a central geographic focus in this 2001 revision, marking the high-altitude transition along the Alamosa and Huerfano county line. This landscape is defined by the protected expanses of the Great Sand Dunes National Park and the Sangre De Cristo Wilderness, where dramatic elevation shifts dictate the flow of the Huerfano River and numerous alpine tributaries like Rito Oso Creek.

Evidence of local land use is visible at the Singing River Ranch and the Corral near Sheep Creek, while water management is highlighted by several high-elevation catchments including Wilson Reservoir and Montez Reservoir. For researchers of historical transit, the map preserves the alignment of established routes like the Ute Trail and Raspberry Trail, reflecting a network of foot and pack trails that predated modern automotive access through these mountain corridors.
