Lake Michigan

Hog Island Reef Perspective View

Return to the Hog Island Perspective Views

Perspective view of colored shaded-relief multibeam bathymetry of Lake Michigan; see caption below.

Oblique view looking north at Hog Island Reef (A). North-south trending bedforms (D) are associated with patches of modern lake sediment composed of sand alligned east-west. The fine and linearly continous morphology of glacial or bedrock outcrop underlie both the bedform and sand patches. The vertical exaggeration is 4x and the distance across the bottom of the image is about 3.5 km.
