Slab City or The Slabs is a camp in the Colorado Desert in southeastern California, used by recreational vehicle owners and squatters from across North America. It takes its name from the concrete slabs and pylons that remain from the abandoned World War II Marine barracks Camp Dunlap there. A group of servicemen remained after the base closed, and the place has been inhabited ever since, although the number of residents has declined since the mid 1980s.
