Big messy rock piles - Horse Hill Left

I was going to write something about quarrying and ceremonialism as a container for discussing my confusion, when they occur together. At this spot, there is not that much justification for the idea of quarrying, only that much of the bedrock has been fractured and used in the rock piles. But if this is debris from quarrying, the rocks would not be so uniform in size. The video contains other hints that this is not just debris. Here is another example:Here are some other things from a few feet away (again, sorry for the blurry pictures - it was raining):[Note how the soil is lower in the gap between the piles and the suggestion of a path winding its way through there.]
