Shortly before I visited the Racetrack Playa for the first time, the mystery of the moving stones had been solved – ice, apparently. Thanks to the flat tire we had encountered at Teakettle Junction, we were behind schedule when we arrived and the sun had already dropped below the peaks of the Last Chance Range to our west. From our spot at the southern end of the Racetrack Playa the photo below shows the playa and Grandstand in shadow with the Last Chance Range, bathed in the glow of the setting sun, in the distance.
