HiRISE: Crater gullies and fractures in Acidalia Planitia
This image shows the gullied western slopes of an unnamed crater (about 10 kilometers wide) in Acidalia Planitia. These slopes have gone through a complicated history of gully erosion of the bedrock layers in the upper section, followed by the … Continue reading

HiRISE: Gullies of Matara Crater
Gullies on Martian sand dunes, like these in Matara Crater, have been very active, with many flows in the last ten years. The flows typically occur when seasonal frost is present. Here, we see frost in and around two gullies, … Continue reading
