ABSTRACT
Wind-abraded rocks, ripples, drifts, and other deposits of windblown sediments are seen at the Columbia Memorial Station where Spirit rover landed. Orientations these features suggest formative winds from north-northwest, consistent with predictions atmospheric models afternoon in Gusev Crater. Cuttings Rock Abrasion Tool asymmetrically distributed toward south-southeast, suggesting active north-northwest time (midday) abrasion operations. Characteristics some such as a two-toned appearance, that they were possibly buried exhumed on order 5 to 60 centimeters by wind deflation, depending location.
