We're not quite at the rim yet, but, we're now close enough to see over the remaining rise and see a good portion of the crater! See todays raw navcam images.

Looks somewhat weathered, slopes aren't all that steep and no obvious outcrops, a bit shallow for its size relative to lunar craters (or fresh Earth craters) but I'll happily retract that if I'm just getting the perspective wrong. Lots more boulders, and at this distance glance nothing that's obviously not more basalt.

Interesting, there is a very bright white dot on the war side of the crater, on the NNE portion of the rim. Shows up in both L/R images so not just noise. It's right about where the MOC image shows the heat-shield impact trench.

On a personal note, had a deja Mars moment yesterday. I'm in Portland, Oregon now and was going for a walk along the Columbia River, where the rip-rap alone the levee is all sharp, angular basalt boulders a couple of feet across, some of which have thin red-brown oxidation rind. Reminded me of the boulder field Spirit is climbing through, even if created by the Corp of Engineers instead of a meteor.
