In the high desert of the San Rafael Valley, a few miles from the United States-Mexico border in Lochiel, Arizona, an adobe schoolhouse has stood for more than a century. Built before 1905, before Arizona was an incorporated state, the schoolhouse served generations of Mexican American students from Arizona and Sonora, cultivating shared cultural experiences, stories, and relationships that transcend physical and political boundaries. Over decades of education and shared histories, it became a place where language and narrative moved freely, even as geopolitical tensions continued to rise along the border. Today, it is one of the last remaining one-room adobe schoolhouses in the United States.
