Unnamed Defrosting Crater (Original NASA/MGS/MSSS b/w Frame)

Caption NASA originale:"This MGS-MOC image shows a Surface in the South Polar Region, covered by CO2 Frost. In this springtime scene, the Frost has begun to sublime so that Sandy Surfaces exhibit an abundance of Dark Spots. The circular depression is probably the remains of an Impact Crater. In summer, the Spotted Surfaces in this image would be darker than their surroundings, because they are patches of Windblown Sand".
