Although cold and dry at present, Mars undergoes major climate changes in which snow and ice are deposited in certain regions. It has been known for some time that Mars undergoes many large changes in its tilt or obliquity because its two small moons lack the gravity to stabilize it, as the Moon

that looks like the ring molds used in baking. They are believed to be caused by an impact into ice. The ice is covered by a layer of debris. They are found in parts of Mars that have buried ice. Laboratory experiments confirm that impacts into ice result in a "ring mold shape." They are also

An modification of the formation of ring mold craters being formed by impact into an ice layer was presented at a Planetary Science conference in Texas in 2018. This new hypothesis involves mantle layers.

Ring-mold craters form when an impact goes through to an ice layer. The rebound forms the ring-mold shape, and then dust and debris settle on the top to insulate the ice.

CTX context image for next image taken with HiRISE. Box indicates image footprint of following image.
Possible ring mold crater, as seen by HiRISE under the HiWish program. Crater shape is due to impact into ice.
HiWish program
Ring-mold craters form when an impact goes through to an ice layer. The rebound forms the ring-mold shape, and then dust and debris settle on the top to insulate the ice.
Ring mold craters on floor of a crater, as seen by HiRISE under HiWish program Location is Ismenius Lacus quadrangle.
