As a child growing up in Central Asia, I saw people piling up stones, sticks, and other debris along the ancient lines people used to control herds and wild animals. The ones built for hunting often had a narrow, funnel-like end, while those meant for managing herds could take on almost any shape. One of the photos in that article looks exactly like the walls I remember from my childhood.

Yeah, but it's an overkill 2m wide and doesn't have a funnel, nor does it use the topography well for kite. And the fortification is a 100m+ square.

Like I said, the materials are similar. The design isn't.
