An elliptical basin found using LiDAR images near the Oxley Nature Center in Tulsa, Oklahoma by Eric Brown has led to a surprising archaeological discovery. The lines carved on the west side of the Tulsa Basin are aligned with the sunrise during the solstices and the equinoxes. The Tulsa Basin is probably the best ancient solar observatory in the United States.
