About this map

The Yampa River carves a deep, winding path through the northern reaches of this Colorado landscape, where much of the river's canyon system is protected within Dinosaur National Monument. This area is defined by sharp topographic relief and isolated plateaus like West Cactus Flat and the prominent Haystack Rock. Human activity in this remote terrain is centered around the Mantle Ranch, which is connected to the wider region by the primitive Mantle Ranch Road and several rugged trails.

Evidence of early resource prospecting and land use is visible at Iron Mine Basin, while the availability of water in an otherwise arid environment is marked by Bear Valley Spring and various ephemeral drainages like Bower Draw and Tepee Draw. South of the river canyon, the terrain transitions into the broad expanse of Bear Valley, bordered by the high spine of Bear Valley Ridge, illustrating the complex geological folding characteristic of Moffat County.
