Demystifying Those Australian Craters
In SF#53, we reported some mysterious craters in Queensland, Australia. Were they excavated by ancient humans? Do they display ancient inscriptions? Australian readers were quick to supply additonal information. It turns out that several years ago, geologists did inspect the so-called "Mystery Craters." This appellation was actually applied by the owners of the land, who have made the craters into a tourist attraction. (This fact alone is enough to raise suspicion!) The geologist's report completely dispells any aura of mystery. Here follows their summary:
"A geological investigation of the 'Mystery Craters" adjacent to Lines Road, South Kolan, indicates that these structures are sinkholes in a laterite profile. The sinkholes have been caused by the collapse of overlying strata into underground voids produced by tunnel erosion."
(Robertson, A.D.; "Origin of the 'Mystery Craters' of South Kolan, Bundaberg Area," Queensland Government Mining Journal, p. 448, September 1979. Cr. R. Molnar.)
Comment. No mention was made in the geologist's report of any inscriptions.
