The Huron Island offer a look at the oldest rocks in the UP, granites and gneisses more than 3 billion years in age. These rock masses are remnants of a mountain range which was slowly worn down and into sand grains and carried down toward the west where they made up the vast sand layers of the Jacobsville sandstone. The same rocks make up the hills we call the Huron Mountains and a few knobs that project from the Jacobsville layers north of L’Anse. These are hard rocks and the glaciers carved spectacular grooves along their surface.
