Clay mineral locations at the rim of Endeavour crater mapped by CRISM
Scientists using CRISM on Mars Reconnaissance Orbiter have mapped locations where CRISM spectral data contain hints of the presence of different kinds of smectite, which is a clay mineral. The hints of clay are what brought Opportunity to Endeavour. The yellow line shows Curiosity's path up to about sol 3654 (May 5, 2014).

Here are the two Arvidson et al. maps on which this map is based:
