Possible Clays and Chlorides near Columbus Crater
Data from other instruments, such as THEMIS and CRISM, imply that chlorides are present here; the CRISM data reveal that iron/magnesium clays are also present.
Sunken and Pitted Ejecta
The objective of this observation was to examine the edge of impact ejecta from a crater to the north-west of this area (north is up, west is to the left).
