The Denver and Rio Grande Western RR winds through the high-altitude terrain of the San Juan Mountains, marking a vital transportation corridor in this 1967 survey. Centered around the small settlement of Cumbres and the nearby Cumbres Pass, the landscape is defined by the steep grades required for rail travel, including a specialized Snow Shed to protect the tracks from heavy winter accumulation. To the north, La Manga Pass and the La Manga Summer Home Group represent the seasonal use of the Rio Grande National Forest, while the La Manga Cow Camp points toward the area's grazing history.
