Book Description
The Colorado River of the West drains a vast system of plateaus. On these plateaus are lone mountains, short ranges and groups of volcanic cones, and the principal effluents of the river have their sources in high mountains that stand on the rim of the great drainage basin. There is no considerable valley along the course of the Colorado River north of the thirty-fifth parallel nor along the course of any of its principal tributaries. The streams run chiefly in deep canons which, with other important topographic features, serve to divide the area into plateaus.
