Marquette Underwater Preserve

The Marquette Underwater Preserve is a protected underwater area in Lake Superior with two separate diving zones. The first section contains multiple shipwrecks from different eras, while the second features rock formations and additional submerged vessels.

The preserve was established in 1990 to protect wrecks dating mainly from the 1800s. These vessels sank when the region served as a major shipping hub for iron ore trade.

The preserve reflects the maritime heritage of the region through wrecks and artifacts resting on the lake floor. Visitors can observe the remains of vessels that document the working life of the Great Lakes.

Visitors need diving skills and should contact local dive shops that offer equipment and guided tours. The best time to dive is during warmer months when water conditions are more favorable.

A Cold War-era military jet aircraft rests on the lake floor alongside the historical vessels. This unexpected mix of maritime and military wreckage makes the site stand out from typical shipwreck locations.
