Ring Mold Craters
Ring Mold Craters look 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 may be an easy way for future colonists of Mars to find water ice.

Famous quotes containing the words ring, mold and/or craters:
“Ring out, ring out thy mournful rhymes,
But ring the fuller minstrel in.”
—Alfred Tennyson (1809–1892)
“Unfortunately, life may sometimes seem unfair to middle children, some of whom feel like an afterthought to a brilliant older sibling and unable to captivate the family’s attention like the darling baby. Yet the middle position offers great training for the real world of lowered expectations, negotiation, and compromise. Middle children who often must break the mold set by an older sibling may thereby learn to challenge family values and seek their own identity.”
—Marianne E. Neifert (20th century)
“Listen.
We must all stop dying in the little ways,
in the craters of hate,
in the potholes of indifference....”
—Anne Sexton (1928–1974)
