A south-facing escarpment in the Northwest Hellas region that was targeted for the phyllosilicates shows instances of bluish rock in this enhanced color image.

CRISM spectra of the bluish material shows that it consists of a combination of chlorite and water ice. The image was captured at the beginning of southern spring, at a time period when south-facing escarpments still retain ices deposited during the winter.
