HiRISE: Delta-like lobes in Aeolis Dorsa
Delta-like lobes in Aeolis Dorsa. Branching fluvial deposits appear similar to others at Aeolis Dorsa which have been interpreted as delta-like. With HiRISE images and elevation models we would be able to measure deposit thicknesses more accurately. Observations like these … Continue reading

The largest delta on Mars?
Planetary Geomorphology Image of the Month, September 1, 2018: Jacob Adler (Arizona State University). Ancient river deltas are found in many locations on Mars [see Di Achile & Hynek, 2010 and references therein], and are formed as sediment drops out … Continue reading

HiRISE: Fans of Roddy Crater
Alluvial fans are found on Earth, Mars, and even Saturn’s moon, Titan. Roddy Crater on Mars is home to several large alluvial fans, which formed as water moved sediment from the mountainous crater rim and deposited it onto the flatter … Continue reading

HiRISE: Cataracts in Kasei Valles
Obviously these are not the kind of cataracts that can develop in the lenses of your eyes, but large erosional scallops that form in river channels, like the Niagara Falls draining the Great Lakes of North America. Cataracts are large … Continue reading

HiRISE: Layers in Galle Crater
This image shows a layered deposit in Galle Crater, located in the Southern cratered highlands. The geologic history of Galle Crater is not well constrained, and it contains a variety of features that have been interpreted as fluvial, lacustrine or … Continue reading

Karun Valles & its braided alluvial fan
Planetary Geomorphology Image of the Month, September 29, 2016: Solmaz Adeli (DLR, Institute of Planetary Research, Berlin). The Amazonian period on Mars, meaning roughly the last 3 Ga, is globally believed to have been cold and hyperarid [e.g., Marchant and … Continue reading
