Delta or fan deposits on Mars indicate past water activity. HiRISE can resolve sedimentary characteristics such as layering, stratigraphic relationship to the surrounding geologic setting or distributary channels that cannot be resolved by other camera experiments. Textural details can reveal the type and evolutionary history of a sedimentary body.
