Lake Superior Alger Underwater Preserve
The Alger Underwater Preserve has several unique diving attractions including underwater caves,
complete shipwrecks, and underwater interpretive trails. The caves are really parts of sandstone
cliffs where waves have eroded the sandstone. The caves are usually only 20 feet deep, though they offer
great shallow water diving.
These caves are found along the Lake Superior coast. They make a great addition to anyone's underwater photograph collection. Divers of all skill levels will enjoy the shipwrecks and they will find that they are in excellent condition. Visibility is almost always excellent, 25 feet minimum, but often it is twice that.
