This observation was taken in Miyamoto Crater in southwest Meridiani, an area near the equator of Mars. This location is near the contact between the hematite-bearing plains unit to the northeast and the clay-bearing unit to the southwest.

Aeolian (wind deposited) processes are active here, which are visible in dunes and ripples, most likely made of basaltic sand. The bedrock contains clay minerals that form in the presence of water. These have been detected in higher concentrations in other areas of Mars such as Mawrth Vallis and Nili Fossae, but detections of lesser abundance have been noticed in Meridiani as well.
