The Rockies are unbelievable. We explored the Niwot Ridge tundra plateau, speckled with wildflowers of every shape and color, looked down on the layered blue mountain ranges below, while snow-tipped peaks gazed at us from still-greater heights. I felt the elevation only in the difficulty breathing I experienced when walking from Point A to Point B - but we walked for more than three miles. Otherwise, it was the height itself that pulsed through my veins, truly on top of the world.

Situated in Southern Colorado, the Great Sand Dunes National Park is an impressive sight. Shaped by winds blowing from and against the nearby Sangre de Cristo Mountains, the piles of sand climb to more than 750 feet (230 meters), making them the tallest dunes in North America. Sand-boarding, skiing and sledding on the dunes are the park’s most popular activities, and there are medium-size slopes to slide on located near the main parking area. A longer hike to the north brings thrill seekers to a 300-foot (90 meter) slope that tumbles onto into Medano Creek.

Lawn Lake Trail climbs to Lawn Lake and Crystal Lake, one of the parks deepest lakes, in the alpine ecosystem and along the course of the Roaring River. The river shows the massive damage caused by a dam failure in 1982 that claimed the lives of three campers.

Above tree line, at approximately 11,000 ft (3,400 m), trees disappear and the vast alpine tundra takes over.[69] Over one third of the park resides above the tree line, an area which limits plant growth due to the cold climate and strong winds. The few plants that can survive under such extreme conditions are mostly perennials. Many alpine plants are dwarfed at high elevations, though their occasional blossoms may be full-sized.[73]
