We set out to solve why a forest in the middle of Uruguay looked like that — and wound up finding something much bigger. Subscribe to our channel! Deep in the geographic center of Uruguay, there’s a peculiar group of trees just a few kilometers down the road from the small town of San Gregorio de Polanco.
