Monument Valley – One of the most majestic landscape on earth in Navajo County

A region of the Colorado Plateau characterized by a cluster of vast sandstone buttes, the largest reaching 300 meters above the valley floor. The elevation of the valley floor ranges from 1,500 to 1,800 meters above sea level.

The valley was once a lowland basin. For hundreds of millions of years, materials that eroded from the early Rock Mountains deposited layer upon layer of sediment which cemented a slow and gentle uplift, generated by ceaseless pressure from below the surface, elevating these horizontal strata quite uniformly one to three miles above sea level. What was once a basin became a plateau.
