Graham Walsh was a park ranger who became fascinated by some very ancient rock art in the Kimberley Ranges in Australia. He spent years recording this art in over 1.2 million photographs. He identifies at least 3 types of art painted by a mysterious race at least 20,000 years ago. He believes they are evidence of a pre-aboriginal culture.
Walsh found 3 different schools of art with eleven different styles. Many wore skirts and head-dresses never seen in current aboriginal cultures or recent paintings. One painting suggests an ocean-going boat with high prows and rudders.
Here is a recording made by the Australian Nine Network’s “Sunday” program, introduced by Jim Waley and reported by Paul Ransley. [The date of the recording is uncertain, probably sometime before 2003.]
