"An image from May 4, 1993, shows an interesting effect. Water from that year’s temporary lake was blown out of its bed to the north by a strong south wind. A shallow scarp, only 20–40 centimeters high, curves around the north edge of the playa and often marks the edge of the lake. But the blue color washes over the scarp in this image."
