1967 Map of Twin Mountains

USGS Topo · Published 1969

About this map

Rio Grande National Forest dominates this section of Saguache County, revealing a high-altitude landscape defined by timber, grazing, and early mineral exploration. The terrain is marked by distinctive geological formations such as the Natural Arch near Eagle Mountain and the prominent peaks of Blue Mountain and the Twin Mountains. The drainage patterns of La Garita Creek, Old Woman Creek, and Geronimo Creek suggest a long history of water management for livestock, supported by the presence of a dedicated Stock Driveway and numerous Pack Trails. Localized economic activity is evidenced by scattered Prospects in the southern reaches, where the mountains descend into English Valley. These features reflect a mid-century era of resource management where traditional ranching infrastructure and forest service surveying intersected.
