Travel writer Belleville has visited some of the most remote and inaccessible sites in the world. Drawn to the water, he has explored reefs, tunnels, underwater caves, murky tropical rivers and cenote (sinkholes sacred to the Maya) visited by less people than have visited the moon. Sunken Cities is a collection of articles from various magazines. As such, the stories are tantalizingly brief, giving only a few pages to each wonder he has visited. I totally bet Adventure is his middle name.
