This series of drawings illustrates why researchers believe many craters are full of ice-rich material. The depth of craters can be predicted based upon the observed diameter. Many craters are almost full, rather than bowl-shaped; hence it is believed that material has accumulated within the bowls
170: 198: 62:. The terrain resembles a human brain. It is believed to be caused by cracks in the surface accumulating dust and other debris, together with ice sublimating from some of the surfaces. The cracks are the result of stress from gravity and seasonal heating and cooling. 114: 186: 68: 422:

23:(CCF) is a landform where the floor of a crater is mostly covered with many parallel ridges. It is common in the mid-latitudes of Mars, and is widely believed to be caused by glacial movement. Areas on Mars called 253: 47:, is believed to be ice-rich. Sometimes boulders are found on concentric crater fill; it is believed they fell off the crater wall, then were transported away from the wall with the movement of the glacier. 459:

Close-up showing cracks containing pits on the floor of a crater containing concentric crater fill, as seen by HiRISE under HiWish program. Location is the Casius quadrangle.
Close-up showing cracks containing pits on the floor of a crater, as seen by HiRISE under HiWish program. Cracks may start as a line of pits that enlarge, then join. Location is the Casius quadrangle.
This series of drawings illustrates why researchers believe many craters are full of ice-rich material. The depth of craters can be predicted based upon the observed diameter. Many craters are almost full, rather than bowl-shaped; hence it is believed that material has accumulated within the bowls in the time since they were formed by impact. Much of the extra material is believed to be ice that fell from the sky as snow or ice-coated dust.
