This location at Yellowknife Bay in Gale crater seems to be a smorgasbord of interesting and kind of weird-looking geological features. We’ve seen the “bubbles,” bright crusts and “flower” (an embedded translucent mineral?) already, but there are more.
In some places, the ground surface looks like “peeling paint” (frozen mud?). After the once-flowing river(s) here dried out a long time ago, did the once-wet surface become frozen and preserved as we see it now?
On some of the rocks, there are rounded globules which look like they are dripping down. Among those are other pits in which a lighter material can be seen, apparently covered for the most part by the other “drippy” material on the surface of the rocks. Are they related to the other bright patches and crusts or “bubble” features?
There are also a lot of bright veins of material on the rocks, often in some of the shadowed areas near the ground. Are they also related to the other bright patches and crusts seen previously, as well as the light-coloured material in the pits just mentioned?
And of course, more of the odd “bubbles” which seem to infest the rocks around here like warts…
