HiRISE: Multi-layered story
A story in layers. Our objective is to examine some very nicely exposed layers in a mesa wall in Aureum Chaos. As the name “chaos” suggests, this terrain is characterized by randomly oriented, large-scale mesas and knobs that are heavily … Continue reading

HiRISE: Gullies on Gorgonum Chaos mesas
Gullies on Gorgonum Chaos mesas. This observation shows part of Gorgonum Chaos, a large cluster of chaotic terrain found in the Southern Hemisphere. Many regions of chaotic terrain are found at the head of large outflow channels that were scoured … Continue reading

HiRISE: We found geology in a chaotic place
We found geology in a chaotic place. The terrain here lives up to its description as “chaotic:” we see small hills, mesas, buttes and valleys. This area is called Oxia Palus, and its debris likely came from Ravi Vallis, which … Continue reading

THEMIS: Aram Chaos’ crumbling mesas
THEMIS Image of the Day, June 27, 2018. In this VIS image of part of Aram Chaos, the surface region is being dissected by linear valleys. As the dissection continues individual mesas will develop, creating the terrain termed chaotic. The … Continue reading

THEMIS: Collapsing ground in Margaritifer Chaos
THEMIS Image of the Day, June 26, 2018. Today’s VIS image shows a small section on Margaritifer Chaos. The term chaos is applied to regions where the surface is being eroded to form mesas. As the surface processes continue individual … Continue reading

HiRISE: Athabasca Valles lava
Athabasca Valles lava. It’s quite the jumbled mess down here. The northern toe of this mesa appears to contact and possibly overlie a rift in the lava crust, giving the impression that the mesa is younger. Beautiful Mars series. [More at … Continue reading
