Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4.5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a shallow sea, with a seabed composed of limestone and dolomite deposits many kilometers thick.[54] Pikes Peak granite formed during the late Precambrian eon, continuing well into the Paleozoic era, when mass quantities of molten rock flowed, amalgamated, and formed the continents about 1 billion–300 million years ago. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime and mud sediments were deposited in the vacated space. Eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin.[55] 

The sun made us lazy, and after following Brian as he made his way upstream I found a wider expanse of sand and gravel, promptly plopping down on a pair of flip flops I had brought in my backpack as a make-shift seat. After identifying the northern harrier hawk over my head, and the savannas sparrows and red-winged blackbirds perched precariously on reeds across the water, I took out my knitting project. I didn’t have to worry about losing Brian; in the valley I could see for miles in both directions.

Located in in southwestern Colorado, Mesa Verde is home to the famous cliff dwellings of the ancient Anasazi people. It is one of the most significant archeological preserve of Native American culture in the US. In the 12th century, the Anasazi start building houses in shallow caves and under rock overhangs along the canyon walls. The most famous of these is Cliff Palace. The Ancient Puebloans constructed it from sandstone bricks, and mortar made from ash, clay and water. It encompassed 150 rooms and 76 open areas. Climatic change and increased population placed the communities under stress and by the late 1270s, the Ancestral Puebloan population began migrating to what is now New Mexico and Arizona.

It is not acceptable to use FLREA (Federal Lands Recreation Enhancement Act) funds to keep the parks open, and the Department of the Interior’s actions likely violate appropriations law,” McCollum said in a statement.}
