re: landslides.
Landslides, and overhanging ledges. This could get a bit wooly. I know for a fact that if I were walking here in a spacesuit, I would not get less than ten feet from that edge without a belay rope. Maybe twenty. If we lose the rover anywhere, it's going to be here.
On the other hand, the rovers are pretty stable. Opportunity could get lucky. Wouldn't it be something to see a photo from the edge, and the next sol's photos from somewhere near the bottom?
