If you zoom in....There are actually 4 "parallel lines" visible in the "sinkole". Maybe they rigged it for a spring Caver / Naturefest party on Mars.

And due to lack of time or oxygen, they had to leave the pit rigged. If you download that image and zoom in, you can see the ropes are clearly above the floor of the cave, maybe by at least 100 feet.
