A pottery shop just off the plaza of Mesilla (locally called Old Mesilla), a historic town adjacent to Las Cruces, the hub city of southern New Mexico. Mesilla was formed in 1848 following a treaty that moved the U.S. border southward into what had been Mexican territory. Several residents resisted American citizenship and formed the new colony of Mesilla below the border. Yet another pact, CALLED the Treaty of Mesilla, moved the border south again, bringing the town into the United States. Photo by Carol Highsmith, 2021.
