That right side looks a little melty:



That's from an IR shot I think. Can wind erosion cause a surface like that?

Kind of a fun one: the relative scales of Navcam, Mastcam M-100, and ChemCam.

... and another variation of Jake - I tried to match the ground color from this MAHLI image




I'm not sure if this makes any sense

Edit: Took a slightly stretched MAHLI image as reference now - bit brighter and less chocolate now

Mmmm... Chocolate...

Can wind erosion cause a surface like that?

I really don't think so. The ventifacts we saw before (like when Spirit was on the rim of Bonneville crater) were all extremely smooth.

[dvandorn]

So... the melty-looking layers have rounded protuberances, but not spheroid. Well, as I said, we'd know more once we got some better-resolution images of Jake. And now we do.

Boy -- those layers are interesting. They can't have formed in the orientation that Jake is currently sitting, and yet the ragged edges of the layers almost appear to have flowed down the side of the rock. Has to be some trick of aeolian erosion. But this is obviously not a dense piece of lava, like the standard ventifacts we see elsewhere in the area and on Mars in general. As has been pointed out, they erode to smooth surfaces. And this thing has sat there long enough to erode down to a pyramid shape, so it has to have something to do with the actual physical strength of the rock faces and the differential strength of the different layers.

Beautiful 3D view across the crater floor looking towards the mountains...

At last, some nice colour stereo images to play with.

I was going to use that as a source for color of the premises as well

But some how purple just doesn't seem like the right color, going to double check the time of day

Sol 45 Navcam pan. Late afternoon, just like I like . Very temporary, still miss some frames.

How Ansel Adams might have photographed the mountains of Gale Crater...

Ok, folks. The bottom 2 images of Jake just came in. Nice rock.

You know what? I'd bet you any money that for much of its existence on the surface, the right side (from our current position) of Jake was buried. The left side has been exposed for far, far longer. Notice how the far right edge bulges out, has not been "planed" down to a smooth edge as the left side has. And there is an entirely different (and more representative of the type) erosion rind on the left side than the jagged, "melting" appearance we see on the right side.
