A Floor-Fractured Crater in Elysium Planitia

We suspect this fracturing might be related to invasive lava, as it resembles weird tilted-facet terrain elsewhere on Mars. With another observation to help create an anaglyph, we can take a look at the outside terrain and see how the elevations compare.
Cutout image is less than 5 km (3 mi) across and the spacecraft altitude was 278 km (173 mi) above the surface. For full images including scale bars, visit the source link.
