A comparison between the two HiRise images of Victoria Crater.
I've taken the original view and have oriented and distorted it to a similar perspective as the latest version.

The absence of any impact features at any scale here is just amazing.

Wow...well spotted, Stu.

The quantity of space imagery being released these days that I don't have time to look through is both marvelous and depressing sad.gif

Remarkable; thanks, Stu!!!

Correct me if I'm wrong, but is that an island in the middle of the channel? Hmmm exp hmmmm....

Gale still gets my uneducated MSL vote. It's just more spectacular than the others.

I could explain the lack of impact features to myself, since this is a small area presumably on a crater wall. But an island seems really interesting.

Is this actually Gale, or is it Hale? I saw a gullies in Hale image posted, didn't see Gale yet.

I agree. I'm particularly concerned about Ebrswalde which I fear looks enticing on a macro scale but like Gusev it could become a disappointment (the serendipitous Columbia Hills notwithstanding), possibly hard sandstone maybe even overlaid with some kind of cap-rock obstruction. I like Gale but I also think the likely breathtaking scenery at Holden would be something to keep Stu's inkwell stirred.

I'm certainly no geologist, but I agree with your interpretation of that. Definitely would be nice to get a second image of it later.

If it's a "baby" gully, it's been a baby for quite a while. The sand ripples evident in the image seem to have conformed to the dip into the linear depression. If this feature were a new gully that is just beginning to form, you wouldn't expect that there would have been time for such conformal ripples to have formed along the topography.
