doesn't look man made to me, I did erosion control after some fires in CA, you see mini ones of those all over (only 2-3" tall, but the same. a little pillar with a stone on top. the action of water hitting bare soil loosens the dirt and allows it to be carried away, the stones on top stop the drops from hitting and loosening the soil underneath.
