Voyageurs National Park - Geology

Geology

Voyageur National Park is located on the Canadian Shield, with the rocks averaging between 1 and 3 billion years old. Formed during the early ages of the earth formation, the rocks of the park were compressed, and folded under tremendous pressure. Then molten flows of lava intruded through the layers creating a mosaic of various gneiss and granites. Over time, additional layers of sedimentary rocks developed on top, to be stripped away by the continental glaciers of the Wisconsin Glacial epoch and earlier.
