Kentucky Blues

Mammoth Cave National Park and other cave systems are part of a limestone belt that defines Kentucky’s landscape with its gently sloping bluegrass valleys. This geography made way for Kentucky to become the thoroughbred horse capital of the world and drive an economy built around events such as the Kentucky Derby. Beneath this limestone bedrock, a water supply often ranked No. 1 for water quality in the United States fuels well-known and developing dive sites that are surprisingly blue.

Échos dans le froid

vAncient beyond description and giant beyond comparison, Lake Superior’s cold and secretive depths hide a multitude of ships that prematurely ended their careers. The largest and farthest north of all the Great Lakes, Lake Superior is in a class by itself when it comes to preserving shipwrecks.

Diving Florida’s Springs

Florida is home to the world’s largest concentration of freshwater springs — the Florida Geological Survey has identified more than 1,000 statewide. There are about 33 first-magnitude springs discharging at least 100 cubic feet (2.8 cubic meters) of water per second.

Howe Sound

With nearly 16,000 miles of rugged coastline and more than 40,000 islands and islets, British Columbia’s Howe Sound features fantastic marine life and spectacular coldwater scuba adventures. Stretching 27 miles from its narrow head under lofty mountain peaks at Squamish to its wide-mouth opening into the Strait of Georgia just northwest of Vancouver, Howe Sound is North America’s southernmost fjord. This sea-to-sky corridor crafted by glaciers and perfected by time seems tailor-made for subsea exploration — reef and wreck, rec and tech.

Plonger dans une capsule temporelle

Thunder Bay National Marine Sanctuary in Lake Huron off the northeastern coast of Michigan has nearly 100 known shipwrecks, and others are still being discovered. The oldest shipwreck there sank in 1849, but many wrecks are from the mid- and late 1800s to the early 1900s. The location, history and variety of ships — from wooden schooners to freighters — make Thunder Bay special. The wrecks are at various depths, ranging from the snorkel zone to recreational and technical diving levels.
