Imperial Sand Dunes
Mammoth Wash - Glamis Dunes - Buttercup Dunes
The Imperial Sand Dunes, sometimes called the Algodones Dunes, are the largest mass of sand dunes in California. This dune system extends for more than 40 miles along the eastern edge of the Imperial Valley agricultural region in a band averaging five miles in width. Rising to heights of over 300 feet above the surrounding desert floor, the dunes are a well-known landmark to local residents and the thousands of highway travelers who pass by them every year. While summer temperatures often rise above 110°F and annual rainfall averages less than two inches, the mild climate between October and May attracts tens of thousands of off highway vehicle (OHV) enthusiasts to the area.
The sand dunes provide outstanding opportunities for recreation. Off-highway vehicle activity is permitted on more than two-thirds of the sand dunes, or over 118,000 acres. The three most popular areas
Mammoth Wash at the north end of the dunes,
Glamis/Gecko just south of State Highway 78,
Buttercup Valley just south of Interstate Highway 8 near the Mexican Border.

The average dust devil is ten to fifty feet in diameter. The chief ingredients for a good dust devil are clear skies, a bright sun, and a dry hot surface. Click here to view video.
Desert Food Chain Video - A food chain constitutes a complex network of organisms, from plants to animals, through which energy, derived from the sun, flows in the form of organic matter and dissipates in the form of waste heat. The food chain’s biological productivity and species diversification depend on factors such as the daily duration and angle of seasonal sunlight, the timely availability of water, the daily swings of seasonal temperatures, the chemical content of the soils, and the availability of nutrients.
