Featuring large sand dunes and small lakes, the state park is the site of North America's tallest single-structured sand dune, which is approximately 470 feet (140 m) in height.^[3][A] The park encompasses 4,800 acres (7.5 sq mi; 19 km²) and features the Bruneau Dunes Observatory, where visitors can use a telescope for stargazing.^[5]

Natural history

Geology

The park's dunes are unique in the Western Hemisphere: where others 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. With prevailing winds blowing from the southeast 28 percent of the time and from the northwest 32 percent of the time, the dunes stay fairly stable, and unlike most dunes, do not drift far.^[6]

Flora and fauna

The state park includes desert, dune, prairie, lake and marsh habitat. Desert wildlife is prominent along with birds of prey and waterfowl.^[6]

Park history

Land for the park was purchased under the Recreation and Public Purposes Act in May 1967. Additional acreage was acquired in 1980 and in 1984, bringing the park's total area to 4,800 acres (19 km²).^[2]

Recreation

Activities include sandboarding, fishing, birdwatching, camping, hiking, swimming, and viewing the stars at the public observatory. No motorized vehicles are allowed on the dunes; climbing and sledding are permitted. There are seven-mile (11 km) and nine-mile (14 km) horseback riding trails around the dunes. An educational center offers natural history displays.^[1] The astronomical observatory is open Friday and Saturday evenings mid-March through mid-October.^[7]
