Dark windblown sand surrounds lighter-colored sedimentary rock formations, exhibiting distinct layers suggestive of a long geological history. The image covers an area of approximately 3 kilometers and shows mesas eroded into layered hills with enough space between to drive a truck. The intriguing formations are a subject of ongoing scientific investigation.
