This month I'm participating in the
A to Z Challenge. My theme this year is Unsolved Mysteries. Today's letter is:
In 1971, a farmer was digging in his field near Bundaberg, Queensland when he discovered 35 water-filled craters.
The owners of the property have turned the craters into a tourist attraction, which has led some to believe they were manmade in nature.
But some geologists
believe the craters are sinkholes that were caused by "the collapse of overlying strata into underground voids produced by tunnel erosion."
Scientists
say the craters are made of sandstone and are at least 25 million years old. So while the property owners are certainly guilty of monetizing this unexplained phenomenon, it appears they've been around a while.
Some prefer to be more imaginative with their ideas. They think maybe the craters were formed by this:
Or perhaps a meteor...
What do you think caused the mystery craters?
