The Order of Rock

So time and time again my focus will stray from in front of me and I spot these rocks that were stacked. I am on the brink of discovering why. I think the picture with one stack has exactly that because it is the first stack you will come across once you start the trail.
Of course the two stacks are the next you will see. This is a prime example of one of those spots that I feel kinda vulnerable to the scene. I think I like the higher ground.
I haven't seen a stack of three yet and have gone well beyond where common sense would have put them. So what does it all mean? Only the stacker of rocks can tell.
