Superior Shoal (original) (raw)
The Superior Shoal is a geologic shoal of approximately 20 square miles (52 km2) located 50 miles (80 km) north of Copper Harbor, Michigan in the middle of Lake Superior, the highest point of which lies only 21 feet (6.4 m) below the lake's surface. The shoal is a hump of Keweenawan basaltic lava flows with ophitic interiors and amygdaloidal tops in an otherwise deep part of the lake, and though fishermen had known of its existence for generations it was only officially charted in 1929 by the United States Lake Survey.

It is one of the known off-shore spawning and foraging habitats for the juvenile lean lake trout. (en) |
