An Unkindness of Ravens :

The power and ancient symbology of the raven carries this story through its historic presence for centuries at the Tower of London to current landscapes including the sandstone monolith of Mount Arapiles in Western Victoria. The ravens seemingly gloating presence adds to the atmosphere at this ancient Aboriginal rock site where many have taken up the climbing challenge and some have fallen. The story moves from this climbing area to one at Hanging Rock - principal scene of the famous novel Picnic at Hanging Rock and the hugely successful movie "Picnic At Hanging Rock" made 50 years ago. An Unkindness of Ravens also looks at the thousands of years of Aboriginal heritage at this former volcanic site and the overall ancient atmospherr of both sites,
