Materials from buried peat beds in Lake Superior near the Apostle Islands in Wisconsin have been critically studied for plant fossils. The deposits are considered as contemporaneous with the one-outlet stage of Glacial Lake Nipissing. Twenty-five species of plants are recorded. These belong to the flora of the Canadian Zone and occur in the region today. A spectrum of the microfossils was also determined.
