Link: Emily's blog post about a possible volcanic feature near Zephyria Tholus.
The idea is layered deposits might be a sign of this as a volcanic feature. Taking the magnified image from that blog post (@ 1/2 hirise resolution) I would say I do see some kind of layering. Tell me if I'm crazy. I've marked what jumps out at me; compare with the original image here. Of course there is a long way between spotting something that looks like layering and making any scientific statement, a distinction made very well in the blog post. But that shouldn't stop us from poking around with it. So am I making things up, or do others see the features I'm marking as layers? |

After reading that blog post, I'm thinking it's time to change Emily's title from"Bloggette par Excellence" to "Eminent Blogospherian".

What a fascinating landscape in the middle of a sea of dust !
Here are a few 3D renderings from a DTM, I created from the central part of the image ( DTM is 200 million polygons at original 50 cm resolution, no texture draping, no vertical exaggeration ). Although probably not very relevant scientifically, the 3D visualizations give an general idea of what the terrain might look like from the ground.. |

Whouaa! We even don't need a fly-by movie on this. Thanks Nirgal.

Thanks, Nirgal, those are really really cool.
I got a brief reply from Alfred, wondering aloud if some of the dust might be volcanic ash. And then this image showed up on Photojournal today, of a Siberian volcano with recent ash flows. http://photojournal.jpl.nasa.gov/catalog/PIA13010 Interesting to compare! Glad you guys are getting something out of this photo! -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
