 In August 2016, around 10 miles of tire tracks were left in the playa by someone driving around it illegally.A photographer visiting in September also noted the initials 'D' and 'K' newly carved into one of the rocks.Although reports at the time suggested investigators had identified a suspect, the vandal had not been identified in March 2018, when a team of volunteers cleaned the tire tracks from the Racetrack using gardening tools and 750 gallons of water.
