Lanfair Valley
Lanfair Valley is located in the Mojave Desert in southeastern California near the Nevada state line. The valley is bounded on the north by the New York Mountains and Castle Mountains, on the east by the Piute Range, and on the south by the Woods Mountains and Vontrigger Hills. Joshua Trees can be found in most of the valley. Elevation is 4,045 feet.
The valley proper is drained southeastwards, then due south by the Sacramento Wash; the wash then turns due-east and combines with the Piute Wash drainage, to immediately enter the west bank of the Colorado River. The dual valley drainage is a U-shape, and the first major dry wash drainage from the west, into the Colorado, south of Lake Mead.
Mojave Road
The Old Mojave Road traverses the valley center, west to east. It passes eastwards just south of center at the Piute Range, and then through a central-southern stretch of the Piute Valley to its eastern terminus at Bullhead City Park, west bank of the Colorado River opposite Bullhead City, Arizona.The Castle Mountains National Monument is part of the north and northeast perimeter of Lanfair Valley,. The Castle Mountains (California) proper is on the water divide between the headwaters of a south-flowing section of Lanfair Valley, and a northwesterly section of the south-flowing Piute Wash of Piute Valley.
The central part of the valley contains the Grotto Hills and Lanfair Buttes.
