IN THE WIND OF THE ANCESTORS
The fact that the ancestors of the North American prairie Indians built more than just tepees in the vast, windy grasslands has only been the focus of research for a few decades. Accordingly, little is known about the sites, although they are located in one of the most (over-)civilised regions of the world. For the descendants of their builders, it does not matter how old these remains are. The main thing is that they are still there and connect the world with the energy of their ancestors.
