Right past the sharp, but warped rim of this ancient impact crater are deposits of winter frost, which show up as blue in enhanced color .
There are two possible science goals that we can study here: what does the terrain look like during the Martian summer, because HiRISE resolution can track changes over time. And second, could the gullies in this crater be a reasonable place to look for recurring slope lineae (or RSL) to occur? The slopes of certain craters have been home these phenomena in other regions as well.
Note: the images here are not map-projected, so approximate north is down.
