New York · 9.1–18.3 m
A maintained shore-accessible dive site in the St. Lawrence River at the foot of Market Street in downtown Alexandria Bay (US side of the Thousand Islands). The Islander was a 125-foot sidewheel steamer built in Rochester in 1871 and lost to fire on 16 September 1909. The wreck lies just offshore in 30-45 feet of water, with some timbers down to about 60 feet, and is a favorite easy/training dive with signage and water access.
Florida · 1.5–36.6 m
Volusia Blue Spring is a first-magnitude spring on the St. Johns River in Blue Spring State Park, famous as one of Florida's largest winter manatee refuges. Open water divers can descend the steep limestone chimney to about 50-60 ft, where a warning sign marks the cave entrance; cave-certified divers can continue to roughly 120 ft against very strong flow. The spring run and boil are closed to all water activities from mid-November to mid-March while hundreds of manatees shelter in the 72°F water.

The sidewheel steamer Pewabic sank within minutes on August 9, 1865 after turning into the path of her sister ship Meteor off Thunder Bay, killing between 75 and 100 people — one of the Great Lakes' worst disasters. Salvagers recovered most of her copper cargo by 1917, wrecking the cabins but leaving the 200-ft hull upright and largely intact with its deck at 155 ft and the bottom at about 165 ft. Today she is a classic entry-level technical dive in the Thunder Bay National Marine Sanctuary, sobering both for her history and for the divers lost on her over the years.

It is the largest and most visited artificial reef in South Carolina waters, popular with both anglers and divers. Marine life includes flounder, sheepshead, black sea bass and seasonal pelagics.
