Beautiful Turnip Rock - North America

Beautiful Turnip Rock - North America

Lake Huron is one of the five Great Lakes of North America. Geologically, it comprises the larger portion of Lake Michigan-Huron. It is bounded on the east by the Canadian province of Ontario and on the west by the state of Michigan in the United States.
Lake Huron is the second largest of the Great Lakes, with a surface area of 59,596 km2 making it the third largest fresh water lake on earth. It contains a volume of 3,540 km3, and a shoreline length of 3,827 m.
Like the other Great Lakes, it was formed by melting ice as the continental glaciers retreated toward the end of the last ice age. Before this, Lake Huron was a low-lying depression through which flowed the now-buried Laurentian and Huronian Rivers; the lake bed was criss-crossed by a large network of tributaries to these ancient waterways, with many of the old channels still evident on bathymetric maps.
