Sand Dunes National Park

Continuing his Grand Colorado Adventure,
Billy Raccoon traveled through hills of sand. There were no trees, the sun was hot and the only plants were prickly.

Great Sand Dunes National Park has 44,246 acres and the tallest sand dunes in North America.
The dunes were formed from sand left by the Rio Grande as it flows
through the San Luis Valley.

Over the ages, winds picked up sand from the river flood plain. As the wind blew over the
Sangre de Cristo Range, it deposited the sand on the east edge of the valley creating the dunes.<- Back                                    Next ->
