Al - I think that is the most likely explaination of the how (and it had occurred to me and I thought I mentioned it in the original post but failed to). Still curious as to the when and will have to talk to the locals and see if I can find out. Fires are not something that happen on the beach these days so I am curious about how old they are.
Bob - Oh, wait. Hold on! :-)
There are some excellent photos posted this month so far.
