At Desert X, a series of outdoor exhibitions in the Coachella Valley, this year’s artwork addresses timely and poignant issues—from the depleting Salton Sea, indigenous peoples’ rights and the political battle at the US-Mexico border. These striking pieces turn sparse land into places for reflection, debate and hope—across more than 50 miles. From Sterling Ruby’s SPECTER to Pia Camil’s Lover’s Rainbow, Artsy staff has picked some of the highlights. Head there to learn more. The works are on public view now through April.
