PlainsPlains – One third of Colorado consists of rolling plains. About seventy million years ago the interior of the North American continent was submerged under a succession of shallow seas. As the continet began to rise the mountains rumbled up in the west. The old seabed was transformed into an east sloping plain. The South Platte and Arkansas Rivers accompanied by abraseive winds, sculpeted the features we know today as the Colorado flatlands. |
