Summary:

In the subsurface of MI, the Munising Formation of the Lake Superior Group includes (descending) the Franconia Sandstone Member, the Dresbach Sandstone Member, the Eau Claire Member, and the Mount Simon Sandstone Member. Unit underlies the Trempealeau Formation of the Lake Superior Group and overlies the Jacobsville Sandstone. Age is Late Cambrian.

Summary:

Munising extended to IN as Group within Potsdam Supergroup. In northwest IN, consists of the Franconia Formation (top), the Ironton Sandstone, the Galesville Sandstone, and the Eau Claire Formation. Unit includes only the Eau Claire in southwest IN, and only the Davis Formation (top) and the Eau Claire throughout most of the state. Underlies Potosi Dolomite and overlies Mount Simon Sandstone.

Summary:

In the southern peninsula of MI, Eau Claire, Galesville, and Franconia Formations are collectively referred to the Munising Group because of their genetic relations. In the northern peninsula, Munising is retained at formation rank. This nomenclature follows Catacosinos (1973, 1974).
