Ice features on Mars. Water ice lobate features are shown wrapping around a small hill. The unusual texture on the ice at the base of this hill, known as 'brain terrain',?may be related to the flow of the ice. Studying ice deposits on Mars may give insights to the climate of Mars and how it has changed over time. Image obtained by the High Resolution Imaging Experiment (HiRISE) instrument on the Mars Reconnaissance Orbiter (MRO).
