A diver checks out the 510-foot 'Spiegel Grove' a few days after it was scuttled in 2002. It sits in around 100 feet of water.
Several thousand certified divers visit the Florida Keys annually to dive a string of sunken vessels and artificial reefs between Key Largo and Key West, prompting the extension through Jan. 1, 2014, of what's called the Wreck Trek Passport Program that rewards divers for logging a series of wreck dives.
As in the inaugural program that debuted in 2010, divers are to receive an official Florida Keys Wreck Trek logbook upon reserving a dive trip with one of more than 30 participating dive shops. They can use the logbook to track their dives and retain it as a memento.
