NASA scientists believe they have a solution to how the gently sloping areas that occur at the bases of taller geographical features formed. These aprons consist of blankets of rocky debris protecting massive glaciers of water ice.
John W. Holt of the University of Texas at Austin, who is lead author of the report said, “altogether, these glaciers almost certainly represent the largest reservoir of water ice on Mars that is not in the polar caps. Just one of the features we examined is three times larger than the city of Los Angeles and up to one-half-mile thick. And there are many more. In addition to their scientific value, they could be a source of water to support future exploration of Mars.”
