Juventae Chasma is a large canyon on Mars that opens to the north and becomes the Maja Valles outflow channel .
The canyon is located north of the Vallis Marineris in the Coprates-Gradfeld and cuts a little more than 5 km into the area of the Lunae Planum . The ground is partially covered with sand dunes . Inside the canyon there is a 2.5 km high mountain with a length of 59 km and a width of 23 km; by Mars Express has found that it is composed of various sulfates. The MRO discovered other sulfates and oxidized iron. There are four other light hills in the canyon (also called light-toned interior layered deposits (LLD's)). Researchers have found that monohydrogenated sulfates lie at the bottom of the canyon, and polyhydric sulfates later deposited on it; kieserite was also found.
