Light-toned layered deposits are found throughout central Valles Marineris. Most of the deposits tend to be towards the center of the depressions, away from the walls that define our solar system's largest canyon. In this image of northwestern Candor Chasma, the light-toned layered deposits are adjacent to the walls. If the deposits are on top of the walls, then we know they were laid down after the chasma had already formed. However, if they are outcropping from within the walls, then they are older deposits that pre-date the chasma's formation. Determining when the light-toned layered deposits formed is important for understanding the geologic history of Valles Marineris, especially because these deposits are hydrated and most likely formed in the presence of liquid water. https://photojournal.jpl.nasa.gov/catalog/PIA24911
