About this map

The Little Snake River meets the Yampa River in this high-desert landscape of northwestern Colorado, carving through the dramatic geography of Dinosaur National Monument. The topography is dominated by deep drainage systems such as Sawmill Canyon and Cross Mountain Canyon, which flank the elevated expanse of Twelvemile Mesa.

Remote ranching life is well-documented through several family-named sites, including Rinker Ranch, White Bear Ranch, and Weaver Ranch. These settlements are linked by primitive routes like CO Road 25 and CO Road 14A, tracing the limited navigable ground between the gulches. This survey provides a precise look at the intersection of protected wilderness and private landholdings in the early 21st century, particularly around the lush river valley of Lily Park.
