Echus Chasma is a chasma in the Lunae Planum high plateau north of the Valles Marineris canyon system of Mars. Clay has been found within it, meaning that water once sat there for a time.
Echus Chasma is approximately 100 km long and 10 km wide, with valleys ranging in depth from around 1 km to 4 km. It is the source region of the Kasei Valles outflow channel, which extends northward from it. It is situated just west of Hebes Chasma, to which it does not connect.
