"Above all it is the rocky region; rocks are strewn along the valley, over the plains and plateus; the cañon walls are of naked rock; long escarpments or cliffs of rock stand athwart the country, and everywhere are mountains of rock. It is the Rocky Mountain region."

Powell, 1876, Report on the Geology of the Eastern Portion of the Uinta Mountains"
