The other side of the mountain? (some pictures)
The Feb. 7th photos from Spirit show that the rover is backing up the hill. Tracks seen in the forward hazcam, and advancing terrain in the aft one.
This is the most recent shot from the advancing aft hazcam. Note the rock pile at top left:
Now, this is a navigation camera shot. Again, look at the rocks nearby. Same rocks. I think we are finally at the overlook, and this is what's on the other side.
