Terrain in Promethei Terra
This HiRISE DTM and its orthoimages show a steep slope that appears blue in enhanced color. The slope cuts through a deposit that drapes the surface and forms one side of a pit, and provides a high-resolution cross-section. The material exposed by the scarp is nearly clean ice.

This image, and several similar slopes in Northern and Southern mid-latitudes, confirm radar detections of ice sheets elsewhere on Mars, and provide high-resolution cross-sections. The icy slopes are steep, and reveal that at this location the ice is more than 100 meters thick. The ice is layered and fractured, and likely formed as a snowpack in the geologically recent past.

These ice exposures are described in more detail in a paper in Science.
