Camp Iron Mountain, California

In early 1942, the 23rd Armored Engineer battalion constructed Camp Iron Mountain with over 40 miles of gravel roads, firing ranges, walkways, and tent areas.  The camp was laid out in a design typical of all DTC camps- a rectangular shape roughly 2-3 miles wide and a mile deep, and rocks were used to line roads, walkways, tent areas, native plants, mess areas, etc...  Camp Iron Mountain is unique in that is has two altars built of a stone- an Episcopalian and Catholic one, each on either side of the camp. Additionally, there are the remnants of a relief map in a 200 x 175 foot area that was built by the Army Corps of Engineers. The map covered the area from Phoenix to Indio, and from Needles to Yuma, and was complete with small wooden signs indicating topographoc features, railroads, roads, mountains, cities and other DTC camps.

The first unit to occupy the camp was the 3rd Armored Division in the early summer of 1942. Other known units who were stationed there include: 183rd Artillery, 951st Artillery Battalion, 7th Motorized Division, 5th Armored Division, 191st Field Artillery Brigade, and the 54th Evacuation Hospital.

Iron Mountain is likely the best-preserved camp, as prior to the establishment of California Highway 62 the area was extremely isolated.  However, this isolation protected the camp from vandalism.  Today, rock-lined walkways and roads as well as unit insignia are still clearly visible at Camp Iron Mountain.

The relief map area.  The mounds of dirt were likely a mountain topographic feature. Relief map area.

Creosote can generally live between 100-200 years, which explains why many of them have circular rings of stones around them. Clearly the men who built the camp wished to embrace some desert landscaping.


This may have been a unit HQ area, or flagpole location. Rocks mark the area where a tent was located.
