THEMIS Image of the Day, May 17, 2018. This VIS image shows an unnamed crater located in Utopia Planitia. This relatively young crater has a steep inner rim, with floor deposits that originate from the crater rim itself.
As craters age, the floor starts to fill with wind blown materials. Regional lava flows can also enter and fill the crater, raising and smoothing the floor. The lack of such modifications indicates the relatively youthful nature of this crater.
