Imperial Sand Dunes
Mammoth Wash - Glamis/Gecko - Buttercup Valley
The Imperial Sand 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. It is roughly bordered on the west by the Coachella Canal which delivers Colorado River water to the fertile agricultural valley to the north.
A major east-west route of the Union Pacific railroad skirts the eastern edge.The dune system is divided into 3 areas. The northern most 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 Highway 78 and continues south just past Interstate 8. The expansive dune formations offer picturesque scenery, opportunities for solitude, a chance to view rare plants and animals, and a playground for OHVs.

Exploring Route 66 - Historic Mohave Desert Sites Amboy Road at Sheeps Hole Pass looks into the big basin of Bristol Dry Lake, which was covered by the sea about four million years ago. Across the salt lake, Amboy Dry Crater rises in the distance. The town of Amboy dates back to 1858; it became a critical gas and rest stop on Route 66 after World War II. When I-40 bypassed it in 1972, Amboy almost became a ghost town. Follow the DesertUSA team as they revisit old Route 66 in the Mohave and take a look at some historic sites along the way.
