On this day ………… 7th February 1829
During an expedition exploring inland Australia, Captain Charles Sturt recorded an unusual phenomenon. It occurred on this day in 1829 near the location of present day town of Bourke in New South Wales. They had stopped in flat, wooded country on a clear, calm day when the party heard a cannon like noise coming from five to six miles away. No one was sure which direction the sound had come from. One of the party climbed a tree to get a better view but saw nothing. To the end of Sturts’ days, it remained a mystery.
