The Great Sand Dunes National Park is open 24 hours a day, all year. Consult the official Great Sand Dunes National Park and Preserve web site for information on fees and camping reservations. There are many events from May through September including the Summer Concert Series and Junior Ranger Day.ecent scientific research suggests that the Great Sand Dunes began forming around 440,000 years ago, after a large inland lake that once covered the San Luis Valley-named Lake Alamosa when evidence of the lakebed was discovered in 2002 - dried up due to climate change.
Dunes can also be formed by strong currents beneath the water. Underwater dunes, called subaqueous dunes, are common in the ocean, rivers, and canals. Shapes of Dunes Dunes can be very large geographic features or just small bumps. Most sand dunes are classified by shape. There are five major dune shapes: crescentic, linear, star, dome, and parabolic. Crescentic dunes are shaped like crescents, or the shape of a wide letter C. The wide side of a crescentic dune is its windward side, with a small, semi-circular slipface on the other side.
