Monterey/Carmel has some good ones; The Sewers, the Laundromat, McDonald's, all named for things on shore near the dive site. Bonaire had a few, like 1000 steps(!) and Oil Slick Reef. Curacao had Wet Suit City (because of fire coral necessating a wet suit). Point Lobos has quite a few strange ones like Montana, Texas, San Diego and Thumbs Up, along with Organ Pipes and Twin Peaks. But the one with the best story has to be Marcos' Pinnacle, named for Marcos Flagg, who was bitten by a GW shark while scuba diving there.
