I think it's natural. At 330,000 years old, there has been plenty of time for trees to jam their roots down in the cracks. :') Still interesting though.

UPDATE: AUGUST 01, 2001
Our crew is currently in South Australia near the Flinder's Range. They are awaiting good weather so that they can visit the location of similar rock formations. Reports and photos will be posted soon.

June 2001: The sample of rock material sent to Viewzone from the Oklahoma site was successfully analyzed by the University of Massachusetts' GeoSciece lab. The interior is made of aggregate quartz while the "shell" is rich in iron. Natural or created? New data to be revealed soon.
