The hilly landscape visible in this observation may appear at first rather bleak, due to the pervasive soils of uniform brightness blanketing most of the area. However, upon closer examination, our enhanced color image depicts in detail the rocky layers in one of these hills. These rocks contain clues pointing to a watery past.

The CRISM instrument on MRO has acquired data over this same region showing that the rocky outcrops contain clays. Clays of similar composition form in terrestrial environments favorable for life, where volcanic rocks are in close contact with water.

Acidalia Planitia is located in the Northern Hemisphere of Mars, between the Tharsis volcanic range and Arabia Terra.
