HiRISE: Gullies in Galle
This image was taken of the hills that resulted from uplifted rocks due to an impact that formed the 230-kilometer diameter Galle Crater. These hills form a segment of a circle known as a “peak ring” and this particular formation … Continue reading

THEMIS: Gullies in craters
THEMIS Image of the Day, February 12, 2019. Today’s VIS image shows part of an unnamed crater in Noachis Terra. Several craters in the southern hemisphere contain floor fill that has subsequently been eroded to form depressions in the fill … Continue reading

HiRISE: Multi-elevation gullies
Gullies probably formed along the bouldery layers in the upper slopes of this unnamed crater within the last few million years. Gullies eroded these crater slopes and transported sediment downslope forming debris aprons multiple times. These older apron surfaces were … Continue reading

THEMIS: Gullies and floor features in Aonia Terra crater
THEMIS Image of the Day, January 17, 2019. Many large gullies dissect the rim of this unnamed crater in Aonia Terra. The inner walls and floor both show evidence of pasted-on terrain — a layer of potentially ice-rich dust. See … Continue reading
