The question I would like asked, "Was it a rocking stone?". Could be the reason to attract dumb apes to an interesting natural features, which they feel compelled to destroy?
Some years ago Mrs BWW and I found one not too far off a popular way. Tempted to use this as a topic and post the clip of video of herself having great fun rocking it with a foot either side, whilst it added interesting percussion to nature's ambience. Then I thought of the sort of person, who would think it fun to tip it over, so I let it lie.
