Field & Stream The Roan Plateau in western Colorado is the “line in the sand” for the Western sportsman who values intact fish and wildlife habitat and a unique sporting opportunity amidst a sea of industrial development. The Roan, which comprises only one percent of the entire Piceance Basin Gas Field, rests above significant reserves of natural gas, but also provides refuge for trophy mule deer, elk, grouse, bear, mountain lion and pure strains of Colorado River cutthroat trout.
