In our previous entries, we have been exploring forgotten sites along California’s Interstate 10 in the Mojave Desert. If you love touching history and walking in the footsteps of those who made it, you will also want to be aware that I-10 cuts right through portions of General Patton’s WWII Desert Training Center.
The following is a brief overview condensed from a BLM (Bureau of Land Management) brochure:
“By the fall of 1941, the world had been at war for two years. Nazi forces occupied most of Europe, and in North Africa, German troops threatened to capture the critical Suez Canal. Later that year, Japanese pilots attacked the U.S. naval base at Pearl Harbor. Congress declared war on Japan. British Prime Minister Winston Churchill urged President Franklin D. Roosevelt to send the U.S. Army to support Allied troops in North Africa. However, America’s soldiers were not prepared for combat in the deserts of North Africa.
In February 1942, the U.S. Army assigned General George S. Patton Jr. to advance desert tank warfare and train U.S. soldiers for combat under the harshest desert conditions possible. In early March General Patton and his staff surveyed the southwestern United States and established the boundary of the Desert Training Center. It encompassed 18,000 square miles of rugged, desolate and largely uninhabited lands within the Mojave and Colorado Deserts in California, Arizona, and Southern Nevada.
Patton established the headquarters for his base camp near Shavers Summit (now Chiriaco Summit), 25 miles east of Indio. The Army named his headquarters Camp Young, after Lt. General S.B.M. Young, the Army’s first Chief of Staff. He identified sites for 12 divisional camps within the Desert Training Center: Camps Essex, Clipper, Coxcomb, Iron Mountain, Ibis, Granite, Rice and Pilot Knob in California; and Camps Bouse, Horn, Hyder and Laguna in Arizona.
He established auxiliary camps that provided logistical support for the divisional camps, including hospitals, medical units and supply depots, and arranged communication logistics with local and regional telephone companies. Patton located the camps near major roads such as Route 66 and railroad communities to transport troops, equipment.
With the surrender of Germany, the U.S. Army decommissioned the Desert Training Center in April 1944, ending the largest simulated operations in the history of military maneuvers.
In January 1947, the U.S. Army returned most of the withdrawn lands to the Department of the Interior, the majority now managed by the Bureau of Land Management (BLM).”
As noted above, the Desert Training Center occupied a huge swath of land, but luckily for those traveling I-10, much activity took place just south of Joshua Tree National Park which is accessed via I-10.
Here are a couple of historic markers you may want to visit during your travels through the area:
- You will find a historical marker (pictured below) along with limited remains for the 36th Evacuation Hospital on Eagle Mountain Road just a short distance off Exit 189 at N33°42.248 W115° 27.072 This site is RV-friendly. Read more about the hospital here.
- There is a historical marker for Young Divisional Camp along a dirt road accessed via Cottonwood Springs Road (south entrance to Joshua Tree National Park) and Exit 168 at N33° 39.852 W115° 47.248 Read more about the camp here.

While visiting these markers, be sure to spend a few minutes exploring the surrounding desert where you are likely to find items discarded during training, remains of roads and hardware from buildings.
This is a great website to read more about the Desert Training Center along with many photos.
If you like to experience history in a museum rather than kicking around in the desert where it happened, you might enjoy a visit to the General Patton Museum where there is a dedicated exhibit to the Desert Training Center. The museum is located off Exit 173 at 62-510 Chiriaco Road, Chiriaco Summit, CA 92201 Click here to learn more.

Boondocking outside Joshua Tree National Park
BLM allows dispersed camping (boondocking) over most of the land it administers, and there are some nice easy-to-access boondocking sites (pictured above) between I-10 and the entrance to Joshua Tree National Park along both sides of Cottonwood Springs Road. Click here for a complete listing of camping options outside of the park including the boondocking sites mentioned.
Visiting the training grounds of those who served, just another adventure in RVing!

Dave Helgeson’s many roles in the RV industry started before he even had a driver’s license. His grandparents and father owned an RV dealership before the term “RV” had been coined, and Dave played a pivotal role in nearly every position of an RV dealership. He and his wife Cheri launched their own RV dealership in the Pacific Northwest. The duo also spent 29 years overseeing regional RV shows. Dave has also served as President of a local chapter of the Recreational Vehicle Dealers Association (RVDA), worked on the board of advisors for the RV Technician Program of a local technical college, and served as a board member of the Manufactured Home and RV Association. Dave’s reputation earned him the title of “The foremost expert on boondocking,” bestowed by RV industry icon, the late Gary Bunzer (The RV Doctor). When he’s not out boondocking, you’ll find Dave in the spotlight at RV shows across the country, giving seminars about all things RVing. He and Cheri currently roam in their fifth travel trailer, with Dave doing all the service, repair and modifications to his own unit.
