HiRISE 3D: Celebdil, Caradhras and Fanuidhol

Sorry, these are not the three mountains of Moria, but rather three impressive peaks in the southern part of the much larger Antoniadi Crater on Mars.

Greetings, @uahirise.bsky.social !

There was once, in the other place, a Hirise Latin feed, with your posts in Classical Latin. Any plans to resurrect the Latinist?

HiRISE 3D: The Remnant Fan

In this observation, a jagged surface protrudes outward from a prominent scarp and associated spur and gully features. This is a candidate remnant fan that likely eroded during a mega flood event.

Impact-Induced Dust Avalanches - From UAHiRISE (NASA) (uahirise.bsky.social) - https://flic.kr/p/2e9TrSD
HiRISE has been imaging new dark features discovered by MRO’s Context Camera, which are mostly new impact sites. In this scene we see what appears to be a new impact cluster and, extending downhill from the craters, new dark slope streaks. These slope streaks are formed by dry dust avalanches. We’ve also seen large new dust avalanches associated with new impacts at previous locations. NASA/JPL/University of Arizona www.uahirise.org/ESP_058514_2140

These ridges are parallel to the crater rim and it’s possible that ice flowed down the higher crater walls towards the crater center from all directions at once.
