HiRISE: Abstract art in Ius Chasma
Sometimes Mars’ surface is just beautiful as seen through the eyes of HiRISE. This is one example on the floor of Ius Chasma, part of Valles Marineris. The region has had a complex history of sediment deposition, deformation, erosion, and … Continue reading

Evidence against vast glaciation in Mars’ grandest canyons
Planetary Geomorphology Image of the Month, April 1, 2019: Lucy Kissick (Durham University, now at University of Oxford). The Valles Marineris (Image 1) form the largest system of interconnected canyons on Mars, up to 2000 km long and in parts … Continue reading
HiRISE: Deposits along the floor of Coprates Catena
Deposits along the floor of Coprates Catena. The rest of this depression has very interesting layered deposits so we’re interested to see if there could be some here too. Coprates Catena is roughly in the center of the Valles Marineris … Continue reading
HiRISE: In the gullies and bedrock of Ius Chasma
This image was acquired in Ius Chasma, a major section of the western portion of the giant Valles Marineris trough. We see a portion of a steep slope with gullies extending downhill (towards bottom of image). Many of the gully … Continue reading

HiRISE: Pitted material and mounds
Pitted material and mounds in Chryse Planitia. This rough-looking material has many meter-length pits. What exactly is this stuff? Chryse Planitia shows evidence of water erosion in the past, and is the bottom end for many outflow channels from the southern … Continue reading
