Juventae Chasma is an enormous box canyon (250 km × 100 km) on Mars which opens to the north and forms the outflow channel Maja Valles.[1]
Juventae Chasma is located north of Valles Marineris and cuts more than 5 km into the plains of Lunae Planum. The floor of Juventae Chasma is partly covered by sand dunes. There is also a 2.5 km high mountain inside Juventae, 59 km long and 23 km wide, that was confirmed by Mars Express to be composed of sulfate deposits.[2] MRO discovered sulfates, hydrated sulfates, and iron oxides in Juventae Chasma.[3]
