One of the very few occasions when we were caught out without a camera. This was before the days of cameras in mobile phones. We were up on higher ground in Kakadu National Park and could see the waterholes scattered through savannah lands after a controlled burn. The indigenous people of the area do this as part of their land management. Onyx for the burnt areas and sterling silver for the pools reflecting the late afternoon sun.

As I didn't have a camera with me, there is no photo with this piece.
