A crater immediately to the east of Biblis Patera. Some questions include: (a) what is the “deposit” on the west side of the crater, seeming to cover the wall/floor interface? (b) what is the floor material; did lava come up into this crater? The “deposit” might be taken by some to bear resemblance to materials sometimes interpreted as ice-related… but this is an equatorial crater.
