Book excerpt: Excerpt from Geology and Underground Waters of the Arkansas Valley in Eastern Colorado Eastern Colorado lies on the western portion of the Great Plains, which extend from the foot Of the Rocky Mountains to the Mississippi Valley. These plains present wide areas of tabular surfaces traversed by the broad, shallow valleys Of large rivers that rise mainly in the Rocky Mountains, and are more or less deeply cut by the narrower valleys of lateral drainage (pl. II). Smooth surfaces and eastward-sloping plains are the characteristic features (pl. III), especially of the Uplands, but in portions Of the region there are buttes, extended escarpments, and canyons of considerable depth. Local areas Of sand hills occur, especially along the rivers and on some of the high plains, where there is much loose material that can be blown by the wind. The altitudes average about feet at the foot of the mountains and about feet along the eastern border of Colorado. Westward the mountains rise steeply to altitudes which reach over feet in Pikes Peak, feet in Spanish Peaks, and feet in Greenhorn Mountain. The principal streams of the region are South Platte and Arkansas rivers. These rise in the mountains, where they flow in deep canyons, but in crossing the plains their valleys are Wide and average about 200 feet below the surrounding higher lands. Near the mountains the Arkansas Valley is bordered in places by cliffs Of moderate height, but to the east the side slopes are very gentle. The altitude in the valley at the mouth of Royal Gorge is feet; at Pueblo it is feet, and at the Kansas line feet. The average grade from Canyon to Pueblo is 15 feet to the mile, from Pueblo to La Junta, 8 feet, and from La Junta to the Kansas line, feet.
