Apologies if it has been brought up before, but this intrigued me: I noticed in some of the horizon Pancam views that just came down from Sols 812 and 856, that there is a "double-bump" feature on the horizon that appears at the same place, at about 99 degrees azimuth. I went back as far as Erebus and the feature appears to be there whenever decent Pancam images are taken of that spot on the horizon. In the distance from just-after-Erebus to Sol 856, the position of this thing on the eastern horizon only seems to have changed by about 2 degrees, more or less.

By my crude math, two degrees over the distance from Erebus makes this thing a honkin' long way away, and that in turn makes it honkin' big. I leave it to the mathematically and cartographically inclined to determine how large a "honkin'" is.

So, to get to the point: Anybody know what this feature is?

Here are some views:

Sol 812
Sol 856
Sol 790

I'll have to switch to my other computer, the one with all the images going back to Sol 1, to see if this thing is still there, say, just after we left Endurance... Unless somebody already knows the answer, that is. Just something to help pass the time until we start driving again

I've been waiting for that large crater rim to appear above the horizon. I hope that this is actually it.

I've noticed, on the PIGWAD Crater Database, that the large crater has a Barlow Crater ID of 413. I do not know if the Barlow catalogue has any information concerning the altitude of the rim. It does not appear to be within the PIGWAD database (that I can see). Does anyone have access to that information?
