It is amazing to think that millions of years ago, around 420 million to be more precise, the London Bridge, Googong area was part of the ocean floor. As the ocean receded the arch, which would become known as the London Bridge Arch, slowly formed by water leaching through the fossiliferous limestone, enlarging cracks, until a passage big enough to let the Burra Creek through was created. The arch reached its present form about 20,000 years ago.
