[I was having trouble loading the images in my post, so I am trying agin here]
I had never noticed how obvious that nearby crater is in the lander data. I charted it out here.
Here is the full pan I made (still needs work), before cropping it down to chart out features.
Also, here is a color super-res view of the more distant crater, visible to the right of the last pan.
Jumpjack, to answer your question, the problem is that this panorama is a fusion of data from both cameras to make up for the fact that much of this area is invisible to at least one of the cameras due to obstruction by part of the spacecraft. Also, Viking's cameras were quite far apart, making visually useful stereo pairs very difficult, even for areas with proper stereo coverage.
