This image covers a thick sequence of stratified rocks that are visible in (Context Camera) CTX images.
These rocks look similar to those in other clay-bearing terrains on Mars and may represent a once extensive deposit that covered the region. HiRISE resolution can be used to the thin beds and to create a digital terrain model.
HiRISE color can aid to determine the composition of these layers, along with its stereo pair to measure bed thicknesses.
This caption is based on the original science rationale.
