    Anyone know what these are? if you look close at the small dark #blotches & #fans they have what looks like a small circular like feature in the middle are they small impact craters?
    I know its probably a noob question but if you don't ask you do not learn.

    I think this place that we call Inca Ciity and these circles are boulders. They are actually quite amazing at this location: they stick out of ice and get warm faster than ice around them. So ice that touches them sublimates first and fans tend to develop starting at those boulders. Nice catch!
