HiRISE: Searching for clinoforms in a possible delta

ESP_039820_1750A delta is a pile of sediment dumped by a river where it enters a standing body of water. Evidence for deltas that formed billions of years ago on Mars has been mounting in recent years. One line of evidence not yet investigated is to search for what are called clinoforms.
