Colorado

2005 Mesa Verde National Park, CO

Mesa Verde (Spanish for green table), occupies just over 52,000 acres of the Colorado Plateau. The correct geological term for the area is cuesta. Cuestas are similar to mesas, but instead of being relatively flat, they gently dip in one direction. Mesa Verde is inclined slightly to the south at about a seven degree angle and has been highly dissected by wind and water erosion into a series of canyons and “mesas.” Elevations range from about 6,000 feet in the canyon bottoms near the southern park boundary to 8,572 feet at Park Point, about ten miles north.

2005 Black Canyon National Park, CO

The Black Canyon of the Gunnison's unique and spectacular landscape was formed slowly by the action of water and rock scouring down through hard Proterozoic crystalline rock.

No other canyon in North America combines the narrow opening, sheer walls, and startling depths offered by the Black Canyon of the Gunnison.
