This was referred to as "Sputnik" crater in the Oct. 6th MER rover and MRO news conference.
Take a look at all the highest resolution Cape Verde HIRISE images on this page to get a better idea of this feature:

There is a roundish feature there, but looking at all highest resolution images, this roundish "depression" is very subdued, if it is even a depression.
But in the 3-D image from the rover there looks to be a deep hole and this hole looks more linear than round. I think what the 3-D image is showing is the gap between the two dark ridges that lie in the roundish feature in the HIRISE images.
This linear gap would not be caused by an impact.

- No, it's not volcanic.
