This unnamed crater on Mars is filled with material of a ‘wrinkled’ appearance. This texture usually implies that material once flowed here, and likely comprised a mixing of rocks, ice or frost, and other soil deposits. The wrinkles seem to have formed in parallel layers which is consistent with material settling onto the crater floor, perhaps in different episodes. Volatiles such as water ice could still be mixed with the rocky sediments to create the observed texture.
The image was captured by the CaSSIS camera onboard the ESA/Roscosmos ExoMars Trace Gas Orbiter on 3 July 2019. The image is centred at 35ºN/169.5ºE. North is up.
