Notes on verification

Multiple independent sources confirm circular stone formations stacked atop one another with earlier layers buried before later construction. However, whether the burial was intentional/ritual (as originally proposed by Klaus Schmidt) or resulted from natural processes like collapse is actively debated among archaeologists, so the underlying mechanism remains contested even though the stratigraphic pattern itself is well-established.
