This blockbuster article from Emily seems to justify a new discussion topic:
http://www.planetary.org/blogs/emily-lakda...le-of-gale.html

So many thoughts, so many questions, I don't know where to start. What about Gusev? Were those basalts actually sandstones too?

And pahrump hills would be part of the Murray formation? Because then if yellow knife sediments are lower than the crater sediments, then the lake bed deposit hypothesis may still be relevant. Has there been any attempt to analyse gale crater floor layers by radar if that's even possible?
