Bicycle Lake

Bicycle Lake. Bicycle Lake is a prominent dry lake bed, or playa, situated within the expansive Fort Irwin National Training Center in the Mojave Desert of San Bernardino County, California. This arid geological feature has served primarily as a vast, flat training ground for the United States Army and has a lesser-known history connected to early 20th-century transportation. Its unique environment and military significance have also led to occasional appearances in fictional media.

Geography and location

Bicycle Lake is located in the northern reaches of the Mojave Desert, approximately 37 miles northeast of the town of Barstow. The playa lies within the boundaries of the massive Fort Irwin National Training Center, a key installation for the United States Department of Defense. The terrain is characterized by its exceptionally flat and hard-packed surface, composed of fine sediments and evaporite minerals like gypsum, which is typical of basin and range topography. The surrounding landscape includes the Soda Mountains to the southeast and the Slate Range to the west, with the broader region being part of the Great Basin watershed. The lake bed is ephemeral, only briefly holding water after rare, intense rainstorms from systems like the North American Monsoon.

History

The area was historically within the territory of the Southern Paiute people before European exploration. In the late 19th and early 20th centuries, the lake bed gained its name from its use by cyclists traveling between the mining districts of Death Valley and the Railroad towns along the Atchison, Topeka and Santa Fe Railway. During World War II, the United States Army established the Mojave Anti-Aircraft Range in the area, recognizing the value of its remote, open terrain. This early military presence was formalized and greatly expanded with the establishment of Fort Irwin in the 1940s, with Bicycle Lake becoming an integral part of the training landscape. The site has seen continuous use for large-scale maneuvers ever since, including exercises during the Cold War and the Gulf War.

Military use

Bicycle Lake's primary modern function is as a military training area. Its vast, flat expanse makes it an ideal location for simulating aerial landing zones, forward operating bases, and large-scale vehicle maneuvers. The United States Army uses the lake bed extensively for exercises conducted by units such as the 11th Armored Cavalry Regiment and visiting National Guard brigades. It is a central component of the Joint Readiness Training Center-equivalent rotations held at Fort Irwin. The lake's surface can support the weight of heavy aircraft, including C-130 Hercules and C-17 Globemaster III transport planes, which practice tactical landings and takeoffs. This training is critical for preparing forces for deployments to theaters like Afghanistan and Iraq.

Ecology and environment

Despite its arid nature, the Bicycle Lake playa supports a specialized ecosystem. The microbial communities within its crusts, including cyanobacteria, are vital for soil stability and nitrogen fixation. The surrounding Mojave Desert scrubland is home to species such as the desert tortoise (a threatened species), kit fox, and Mojave rattlesnake. Vegetation includes creosote bush, Joshua tree, and various cacti. The area is subject to strict environmental protections under laws like the Endangered Species Act and the Sikes Act, requiring the United States Army to conduct careful environmental management to balance training with conservation, often in coordination with the Bureau of Land Management.

In popular culture

The stark, otherworldly landscape of Bicycle Lake has made it a filming location for several productions. It notably served as a stand-in for the desert planet Jakku in the Star Wars sequel film *The Force Awakens*. Its terrain has also been featured in various television commercials and music videos seeking a desolate, Martian-like aesthetic. The lake bed's association with major military training provides background context for documentaries about the United States Armed Forces, including programs aired on the History Channel and Discovery Channel.
