2010 Map of Twelvemile Mesa

About this map

The Little Snake River joins the Yampa River in this arid landscape of Moffat County, where high desert plateaus and deep drainage systems define the geography. The map captures a high-plateau cattle-ranching culture, where named sites like Rinker Ranch, White Bear Ranch, and Carlson Ranch are established near the life-giving water of the river bottoms. Much of the northern terrain falls within the boundaries of Dinosaur National Monument, protecting the stark geological features that rise from the valley floor. To the east, the prominent uplift of Cross Mountain looms over Twelvemile Gulch, while the expansive Twelvemile Mesa dominates the southern reaches of the quadrangle. The sparse road network, including County Rd 153 and County Hwy 123, follows the natural contours of the land, connecting isolated homesteads like Weaver Ranch across a network of dry washes and canyons.
