Great Sand Dunes National Monument

The scale of the Great Sand Dunes can be difficult to judge. The dunes you see from here are only the front lines of a sea of dunes that covers many square miles.

How far do the dunes extend into the distance? The dunes are 8 miles (13km) across. It would take a strong hiker 5 hours to cross them.

How high is the tallest dune? The highest dune rises nearly 700 feet (200m) -taller than a 50 story building.

How much sand is in the dunes? If all the sand was loaded into railroad cars, the train would be long enough to circle the globe more than 20 times. If the sand were spread out ankle-deep it would cover 1/10 of Colorado.

How large are the Sand Grains? The grains that make up the dunes are tiny, about 1mm in diameter, but most measure between 1/8 and 1/4 mm. Smaller particles blow away over the mountains.
