While going through some images of Acidalia, I came upon the following:

http://www.msss.com/moc_gallery/m19_m23/full_jpg_non_map/M19/M1900532.jpg

in which, somewhat over half way down the image, there is a multi-ringed circular formation much like the Meridiani "Bullseye." There is a conical pit next to the formation which may or may not be related in any way.

There is nothing about these features that says to me that either of them is of impact origin.

The apparently layered mound (it is definitely a mound to my eye, anyway!) in this image:

is intriguing. The mound sits in a moat, and its sunny (upper) side is far smoother than its shadowed side. I wouldn't be surprised if this mound is largely ice, and we are seeing it sublimate away before our very eyes! It could have been pushed up from below, something like a pingo. The apparent layering could be representative of the layered surface in this region.

Interesting!

Cheers, B R Felix
