Bruneau Dunes State Park

Bruneau Dunes State Park is a state park of Idaho, USA, featuring several large sand dunes and two small lakes. The park is located south of Mountain Home, Idaho, outside of Bruneau. The park is the site of North America's highest single-structured sand dune which is approximately 470 feet (140 m) high. (North America's highest multistructured dune is at Great Sand Dune National Park in Colorado and is approximately 660 feet (200 m) higher than its immediate base.) The park is also the site of the Bruneau Dunes Observatory, where visitors can use a telescope for stargazing.

Natural history

Reportedly the tallest single-structured sand dune in North America rises to 470 feet (140 m) high above small lakes. The dunes at Bruneau Dunes State Park are unique in the Western Hemisphere. Other dunes in the Americas form at the edge of a natural basin. The Bruneau dunes form near the center. The basin has acted as a natural trap for over 12,000 years. The dunes may have started with sands from the Bonneville Flood about 15,000 years ago. The prevailing winds blow from the southeast 28 percent of the time and from the northwest 32 percent of the time, keeping the dunes fairly stable. Unlike most dunes, these do not drift far.

State park

State parks or provincial parks are parks or other protected areas managed at the sub-national level within those nations which use "state" or "province" as a political subdivision. State parks are typically established by a state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state, and of some states of Mexico. The term is also used in Australia, though the distinction between state and national parks there is different. The Canadian equivalent term is provincial park. Similar systems of local government maintained parks exist in other countries, but the terminology varies.

State parks are thus similar to national parks, but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., regional parks or county parks. In general, state parks are smaller than national parks, with a few exceptions such as the Adirondack Park in New York and Anza-Borrego Desert State Park in California.
