Right in front of you, in the middle, you can see that big portion of rock that is lower than the rest. Notice it has trees growing on top and it fits perfectly into the notched portion to the right of it...THIS is why Nickey's eyes were closed. Scientifically, this is caused when the softer rock underneath erodes faster than the rock above. Eventually, the stress becomes too great and a large chunk breaks off and drops straight down. We, well I, saw this a lot; Nickey didn't.
