 | | The Green River Basin, the Uinta Mountain region, and the Colorado Plateau, which constitute by far the greatest and most characteristic part of the vast region drained by the Colorado River north of central Arizona, are relatively simple in topographic expression, physiographic expression, and physiographic history. |
 | | From the hogback across the plateau top, nearly horizontal Paleozoic rocks form the surface, and at their eastern limit are overlapped by steeply tilted Mesozoic beds, the remnants of strata that once overarched the plateau and joined those in the Grand Hogback. |
 | | Unlike the dry plateau country of northern Arizona or the mountain ranges to the south, Verde Valley is destined, both because of its character and location, to be developed as an important source of water and of agricultural produce. |
