1982 Map of Blanca Peak

About this map

The high peaks of the Sangre de Cristo Mountains dominate this 1980s landscape, creating a dramatic physical divide between the agricultural San Luis Valley and the eastern Huerfano river basin. To the west, the massive Great Sand Dunes National Monument and Wilderness sits at the foot of the range, bordering the large Luis Maria Baca No 4 land grant. The transport network of the era is defined by the Denver and Rio Grande Western railroad line passing through Mosca and Hooper, while an Old Railroad Grade in the southeast hints at earlier industrial routes near Muleshoe. High-altitude settlements like Crestone, Liberty, and Duncan are positioned along the mountain front, contrasting with the river-valley communities of Gardner, Red Wing, and Chama to the east. Notable summits including Blanca Peak, Crestone Peak, and Greenhorn Mountain provide the primary geographic anchors for this quadrangle.
