Also visible in a Context Camera image, our high resolution picture shows layers exposed where the crater ejecta has been eroded.

Some of the layered material is light-toned. Rocks containing sulfates have a light tone compared to isolated rocks examined by landers and rovers at other locations on Mars. Rocks in Meridiani have strong evidence for past water, including the mineral jarosite.

With this image, we can cross-dating the relative age of the impact with that of the valley system, as well as learning more about the fluvial and morphology characteristics of area.
