CRISM: Hydrated minerals of Cydonia Colles
In this scene we observe the knobs within the northern lowlands (Acidalia Planitia) that are Fe/Mg phyllosilicate-bearing (pink-blue) and small, patchy exposures of hydrated silica (green) surrounding the knobs. Previously, phyllosilicates have only been found within impact craters in the … Continue reading

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 in a crater in Acidalia Planitia
Gullies in a crater in Acidalia Planitia. The objective of this observation is to examine gullies on the north wall of a crater. The slope looks quite steep and the gullies are fairly straight. Beautiful Mars series. [More at links]

HiRISE: Fans and valleys
An impact crater approximately 23 kilometers across is home to fan-shaped deposits that extend from the rim and sit on the interior crater floor. Thick beds with varying tone are exposed along the edge of the fan. Shallow valleys that … Continue reading

THEMIS: Blast scour at Bonestell Crater
THEMIS Image of the Day, April 17, 2018. Bonestell Crater is a relatively young crater located in Acidalia Planitia. The grooved surface of the ejecta blanket is evident in this VIS image. The grooves were likely eroded by the outward … Continue reading

HiRISE: Troughs with axial ridges in Acidalia Planitia
Troughs with axial ridges in Acidalia Planitia. There are large, hundreds of meters in length, troughs in Acidalia Planitia, with high axial ridges down the center. While they appear fairly bland in Mars Orbital Camera images, we can see better … Continue reading
