Llano del Rio is one of the most distinctive ghost towns in the United States. Like many Utopian communities, it lasted only a short time — a few hopeful, productive years — before being abandoned. Unlike most, however, it was built to last — its granite foundations sourced from nearby mountain ranges — and, still in the middle of nowhere even 90 years after it was inhabited, it’s been allowed to linger on, a monument to the disappeared past on the edge of a vast desert.
