When the last U.S. Census canvassed Slab City, a remote, self-governed community of artists, retirees, anarchists and homeless people in southern California’s desert, most of its residents claimed ownership of the plots they occupied as “free and clear.” And yet Slab City itself occupies land that is public, as firm in this designation as the resolve of those who live there. Often called the “last free place,” this square-mile plot is one of the remaining Section 36 areas, which were originally reserved for the state’s public schools when each township was laid out by the National Ordinance’s land surveys that blanketed the American West in an invisible but all-encompassing grid. Consequently, the state of California hosts an array of one-square mile pockets of land. Among these, Slab City is a camp that bears the ongoing question of how land—environmentally inhospitable yet relatively hospitable in its public status—might host practices of self-determination, self-regulated community, and national identity. Veritable blind spots of land management, Section 36 areas contrast other more regulated, though comparable, practices on public and private lands. The Bureau of Land Management oversees Long Term Visitor Areas where campers can park trailers across vast territories for extended periods of time, and Walmart plays host to cross-country travelers who overnight in its parking lots—a permutation of recreational camping known as boondocking. But what happens in the absence of oversight? In places where the campsites become permanent? In times when those living there have arrived not only by choice but also in many cases out of necessity? Legacies of a country’s organizational matrix, Section 36’s pockets of land linger as residual pieces of frontier mythologies, as testaments of the arbitrariness of the grid and its land policies, and as fertile ground for alternative practices of adapting to inhospitable environments and making home in improvised communities. This essay seeks to understand how Section 36 land hosts contemporary intersections of public space and freedom.
