Underwater Wonders of the National Parks A Diving and Snorkeling Guide Compiled by the National Park Service

Perhaps the single best-kept secret about our National Parks (NP) is the underwater realm that they include: millions of acres of submerged lands, only a small fraction of which has been explored by divers. From geysers on the bottom of Yellowstone Lake, to the coral reefs of the Dry Tortugas, to steamers sunk in the frigid waters of Isle Royale in Lake Superior, to the kelp forests of the Channel Islands, the NP have much to offer the diver. Almost all of the 61 NPS areas with significant water holdings are of some interest to divers. This guide introduces divers & others interested in water sports to this dimension of the NP, such as snorkeling rare coral reefs; shipwreck diving; & underwater archaeological sites.
