Jeff N. Thanks for the crayola outlines. Your interpretation fits with what I believe I see as well. One question about the possible shadow. For those who have been there, is the shadow consistent with where the sun would have been positioned when Bevington was at the island? Most especially, if there is anyway to know what time of day, approximately, that the photo may have been taken. Since the beach can be seen in the background I would think that establishing the general direction of the sun, and from that where a shadow should fall, shouldn't be too difficult. If the shadow is wrong then the object may be just a flaw. My opinion, I see a gear. But, I've been wrong before. At least I thought I was, turns out I was wrong. LTM -John
