Mesa Verde National Park
About 100 million years ago, Mesa Verde and the surrounding area were covered by a shallow sea, and sand deposits cemented into the sandstone layers that make up much of the park's geology. As the sea withdrew to the south, uplift in the area created the high plateau that is Mesa Verde. Over time, small streams have cut channels into the plateau, creating steep canyons which separate the individual mesas. Traveling south, the mesa extends like fingers into the desert.
From the park entrance in Montezuma Valley, the elevation climbs steeply to the rim of the flat mesa top. Elevations in the park range from about 6,100 feet (1,860 meters) to about 8,400 feet (2,560 meters) above sea level.
