This site was designated as an ACEC due to the historical significance of the area. Camp Iron Mountain is the best-preserved divisional camp today, and is famous for being one of two camps that have rock chapels that still stand. The chapels that are found are of Protestant and Catholic denomination. A large relief map is also found at the site. The map is 200 feet by 175 feet and represents the entire Desert Training Center/California-Arizona Maneuver Area to scale. The map also had wooden signs that represented large topographic features including Divisional Camps. Highways, railroads, and the Metropolitan Water District (MWD) aqueduct were also displayed.
