Whipstick rock stacks

[JohnEagjehawk]

New here, but been reading this site for a few weeks.
So I was just after other people's opinions on these rock stacks in the Whipstick, bushland just north of Bendigo, Victoria.
You'll see the smaller ones, and the larger one has been made on an ant's nest. I took a few pics of this one.
I have seen a few other stacks around and will take some more pics on the weekend and spend a bit of time walking around the area if people are interested.
Also are there any members from the Bendigo region?

Unfortunately for those of us that dabble in this pursuit every tom , dick and Harriet has decided that its now fun to build bloody artistic rock stacks everywhere they go in the bush .
Apparently Carnarvon Gorge has a spot with heaps of them now , a little like the graffiti on the Nambucca break wall.
So a bit hard to consider it as real evidence , unless it is perhaps 1 way out in an unusually hard to reach place or where the average punter doesn't normally tread ??
