HiRISE image: RSLs and colorful fans along Coprates Chasma ridge

This site along a Coprates Chasma ridge shows what are called recurring slope lineae (or RSL) on generally north-facing slopes in northern summer/southern winter (latitude 12.9 degrees S, longitude 295.5 degrees E). With an animation constructed from multiple co-located images, we can detect surface change and constrain the RSL phenomena. An enhanced color image illustrates the “greenish” fans… [More at link]
