The scorching Arizona sun beats down on the barren landscape where Camp Hyder once stood, ten miles north of tiny Dateland. Today, little remains except scattered concrete foundations, the faint outlines of roads, and occasional debris half-buried in the desert sand. Yet this seemingly unremarkable patch of Yuma County desert once played a crucial role in preparing American soldiers for the harsh realities of World War II combat. As part of the largest military training ground in U.S. history, Camp Hyder represents a unique chapter in Arizona’s contribution to the war effort—a place where American troops were hardened under the command of General George S. Patton before being deployed to battlefields across the globe.
While no original buildings remain, visitors can explore the open desert landscape where Camp Hyder once stood. The remnants include concrete foundations, crumbling rock outlines of barracks, tent pads, old roads, and other subtle signs of the vast camp layout. With a little imagination, visitors can picture the thousands of soldiers who once drilled here under the blistering sun. It’s best suited for self-guided exploration, so bringing a historical map or GPS coordinates is highly recommended.
Camp Hyder was one of several camps under the Desert Training Center, a military innovation that mimicked the harsh environments of places like Tunisia and Libya. Learning about this training program offers deeper appreciation for the conditions soldiers faced overseas. You can bring along or download military archives, veteran memoirs, or original training manuals to enrich your on-site experience. Although there’s no official interpretive center at Camp Hyder, the history is accessible through online resources and DTC historical records.
Camp Hyder is part of a broader network of WWII-era camps, including Camp Laguna, Camp Bouse, and Camp Horn, each with its own story. Creating a road trip itinerary that links several of these sites provides a comprehensive view of the scale and ambition of the Desert Training Center. While these locations are all largely undeveloped, their historic footprints paint a vivid picture of wartime innovation and grit.
The landscape surrounding Camp Hyder is starkly beautiful, with expansive desert vistas, saguaro cacti, ocotillo, palo verde, and seasonal wildflowers after rare rains. The isolation makes it a peaceful place for nature walks, landscape photography, or quiet reflection, especially during cooler months. Visitors might also spot wildlife like desert foxes, coyotes, jackrabbits, and a variety of birds adapted to the harsh terrain.
The roads to Camp Hyder are mostly unpaved and can be rough, so a high-clearance or 4WD vehicle is recommended. This makes the site popular with off-road adventurers and overland explorers who enjoy navigating desert trails. It can be a great stopover on a longer drive through southern Arizona’s historical and natural landmarks.

Camp Hyder was established in August 1942 as one of 15 camps within the Desert Training Center (DTC), later renamed the California-Arizona Maneuver Area (CAMA). The creation of this massive training complex was a direct response to America’s urgent need to prepare for desert warfare against the German Afrika Korps in North Africa. General George S. Patton Jr., having participated in army maneuvers in the Mojave Desert during the 1930s, knew the harsh southwestern desert would provide ideal conditions to prepare troops for the North African campaign.
The Desert Training Center stretched from Indio, California eastward to within 50 miles of Phoenix, Arizona, southward to Yuma, and northward into southern Nevada. At 18,000 square miles, it became the largest military training facility in the world. Within Arizona, the facility included Camp Hyder along with Camps Bouse, Horn, and Laguna.
Camp Hyder’s strategic location near both rail lines and highways made it an ideal logistics hub for troop movements and supply distribution. The camp was built to accommodate division-sized units, which could include thousands of soldiers training simultaneously in the brutal desert conditions.
Today, Camp Hyder exists primarily as scattered remnants across the desert landscape. The once-bustling military installation has been largely reclaimed by nature, though attentive visitors can still discern the outlines of streets, building foundations, and infrastructure that hint at its former purpose.
Near the camp’s original railway station, two large stone columns once marked the entrance to the facility, though their current condition is uncertain. The harsh desert environment and seven decades of exposure to the elements have erased most visible signs of the thousands of troops who once trained here. Agricultural development in the surrounding area has further obscured some of the site’s historical footprint.
For visitors today, accessing Camp Hyder requires determination and respect for both private property and potential hazards. Warning signs about unexploded ordnance may still be visible in certain areas, a sobering reminder of the live-fire exercises conducted during the camp’s operation.
At its peak of operation, Camp Hyder featured a comprehensive array of military facilities designed to house, train, and prepare soldiers for desert warfare. The camp included shower buildings, latrines, an outdoor theater for instruction and entertainment, wooden tent frames for soldier housing, and essential water infrastructure including two 10,000-gallon storage tanks and a water treatment plant.
Training facilities were extensive, with firing ranges designed for .30- and .50-caliber machine gun practice as well as artillery. The camp also included specialized areas for anti-tank mine training, reflecting the complex tactics soldiers would need to employ against German armor divisions in North Africa.
A distinctive feature connected to Camp Hyder was the Agua Caliente natural hot spring, which the Army developed for soldiers’ use on the land of the Agua Caliente Ranch. This facility provided a rare luxury in the otherwise spartan training environment, offering troops a chance to relax and recover from the physically demanding desert exercises.
While specific information about newspapers published at Camp Hyder itself is limited, military installations of this size typically maintained communication channels to disseminate orders, training schedules, and boost morale. The Army likely produced bulletin-style communications or contributed to larger military publications that circulated throughout the Desert Training Center.
Military communications during this period would have focused on training objectives, safety protocols for desert survival, and news from other theaters of the war. These publications served as vital connections between the isolated desert camps and the wider war effort, helping soldiers understand their role in the global conflict.
The railroad played a pivotal role in Camp Hyder’s functioning, as it did for many of the Desert Training Center installations. The camp utilized the railway station at Sentinel, Arizona, located south of the main installation. This connection to the national rail network was essential for transporting troops, equipment, and supplies to the remote training location.
Additionally, to support air operations connected to the camp’s training mission, the Dateland Air Force Auxiliary Field was established southwest of Camp Hyder. This airstrip, named after the nearby Dateland road stop, supported both small observation aircraft like the L-4 Piper and larger planes used in training exercises. The airfield officially opened on January 1, 1943, under the direction of the Yuma Army Airfield, and was utilized by the 3037th Army Air Force Base Unit.
The integration of rail, road, and air transportation around Camp Hyder demonstrates the comprehensive approach to military logistics that characterized the Desert Training Center’s operations.
Among the units known to have trained at Camp Hyder were elements of the 77th, 81st, and 104th Infantry Divisions. Over 13,000 troops received training at Camps Horn and Hyder combined during their periods of operation. These soldiers endured punishing heat, dust storms, scorpions, rattlesnakes, and other desert hazards as part of their preparation for overseas deployment.
Daily life at Camp Hyder followed rigorous military schedules, with pre-dawn reveille, extensive field exercises, weapons training, and tactical maneuvers filling most days. Troops learned essential desert survival skills, including water conservation, heat illness prevention, and navigation techniques that would prove crucial in North African and later European campaigns.
Evening hours might find soldiers attending instructional films at the outdoor theater, writing letters home, or simply recovering from the day’s physical demands. The shared hardship of desert training forged strong unit cohesion among troops who would soon face combat together overseas.
Camp Hyder operated for less than two years, closing in May 1944 as the need for specialized desert training diminished following Allied victories in North Africa. During the Desert Training Center’s brief existence, however, nearly one million American soldiers received essential combat preparation in its harsh environment.
The camp’s historical significance extends beyond its physical footprint—it represents America’s rapid mobilization capacity during World War II and the innovative training approaches developed to prepare civilians-turned-soldiers for the unique challenges of modern warfare. General Patton personally oversaw the initial training at the Desert Training Center until November 1942, when he departed to lead American forces in North Africa, putting into practice the very tactics he had helped develop in the Arizona desert.
Camp Hyder and the broader Desert Training Center demonstrate how America’s southwestern deserts, often seen as empty wastelands, became vital proving grounds that helped shape the outcome of World War II. Today, this history is commemorated by historical markers near Dateland, Arizona, including one erected in 2002 by the Lost Dutchman, Billy Holcomb, John P Squibob, Queho Posse, Peter Lebeck and Matt Warner Chapters of E Clampus Vitus in cooperation with Dateland Elementary School.
Visitors interested in Camp Hyder’s history should approach the site with appropriate caution and respect. Much of the former camp area may be on private property or contain potential hazards including unexploded ordnance from training exercises. The historical marker located at the Dateland Travel Center (about 65 miles east of Yuma at Exit 67) provides information about the camp without requiring access to potentially dangerous areas.
For those wishing to learn more about the Desert Training Center and its role in World War II, the General George S. Patton Memorial Museum near Chiriaco Summit, California offers extensive exhibits on the training operations and Patton’s military career.
The wind-swept remains of Camp Hyder stand as a testament to a unique moment in American military history—when vast stretches of the southwestern desert became training grounds for global war. Though its active life was brief, the legacy of Camp Hyder lives on in the victories achieved by the soldiers who trained there and in the preservation efforts that keep this chapter of Arizona history from vanishing entirely into the desert sands.
As one stands at the site today, imagining the thousands of young Americans who once prepared for war amid these harsh surroundings, Camp Hyder offers a powerful reminder of both the impermanence of human endeavors and the enduring impact of historical events that shaped our world.
