===Algodones Sand Dunes===
[[File:Imperial sand dunes.jpg|thumb|right|The Algodones Dunes]] The name [[Algodones Dunes]] refers to the entire geographic feature, while the administrative designation for that portion managed by the [[Bureau of Land Management]] is the "Imperial Sand Dunes Recreation Area" (sometimes called the "Glamis Dunes"). The Algodones Sand Dunes are the largest mass of sand dunes in California. This dune system extends for more than {{convert|40|mi|km|abbr=out|sigfig=|sp=us}} along the eastern edge of the [[Imperial Valley]] agricultural region in a band averaging {{convert|5|mi|km|0}} in width. A major east–west route of the Union Pacific railroad skirts the eastern edge. The dune system is divided into three areas. The northernmost area is known as Mammoth Wash. South of Mammoth Wash is the North Algodones Dunes Wilderness established by the 1994 California Desert Protection Act. This area is closed to motorized use and access is by hiking and horseback. The largest and most heavily used area begins at [[California State Route 78|Highway 78]] and continues south just past [[Interstate 8]]. The expansive dune formations offer picturesque scenery, a chance to view rare plants and animals, and a playground for [[All terrain vehicle|ATV]] and off-roading enthusiasts. The dunes are also popular in film making and have been the site for movies such as ''[[Return of the Jedi]]''.<ref name="dunes">{{cite web |url=http://www.desertusa.com/sandhills/sandhills.html |title=Algodones Sand Dunes|access-date=August 5, 2009}}</ref>
