HiRISE: Surface patterns of glacier-like landforms
The rotational axis of Mars is currently tilted by about 25 degrees, very similar to that of the Earth (at 23.4 degrees). However, while Earth’s axial tilt (also known as “obliquity”) tends to change very slightly over time (almost 3 … Continue reading

Debris-covered glaciers on Earth and Mars
Planetary Geomorphology Image of the Month, June 30, 2016: David P. Mayer (University of Chicago). Debris-covered glaciers are glaciers whose ablation zones are at least partially covered by supraglacial debris. On Earth, debris-covered glaciers are found in all major mountain … Continue reading

HiRISE: Dramatic shadows over a fossil glacier
This image was acquired near the Martian winter solstice, when the sun was low over the horizon at this location. The resulting illumination produces dramatic accentuation of subtle topography. The image is centered on a fossil glacial flow, no longer … Continue reading

Mars has mid-latitude belts of glaciers
Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as the surface of the … Continue reading
