Interesting, but I wouldn't call that a "cliff", as it looks to be just some centimetres high.
Looks to be or is?
if so I guess there must be some really tiny people on Mars :o
Yes LOL That is the premise of those that found the hole. They go so far as to say its a window and the door is further over
Here is the tiny Martian from a few years back :D
