1. Light-toned sulfate/clay layer at Gale crater Latitude/longitude: X North, Y East Rationale: Location of transition between phyllosilicate-rich units and sulfate-rich units Morphology and Mineralogy: Location is in filled channel carved into layered rocks of mound. Both phyllosilicate and sulfate-bearing units. What will the rover specifically do here? Study differences in lithology between the phyllosilicate and sulfate units, characterize channel fill, and work upsection in lower mound stratigraphy.
