Beautiful phenomena

We went out this morning heading towards Little River and Birdlings Flat. As we got out of town there was quite at thick fog hanging in the hills.. It is our Nature Photography club 20th Anniversary weekend. It was great to get out with like minded " nuts". ..on our way back from lunch at Little River, we stopped to shoot some birds on the misty lake. I had wrong lens for "shooting" birds I was delighted to find this " fog bow".... Such an amazing phenomena.
