Open File Report LXV – Geology of Chippewa County, Michigan - VerWiebe – Page 1 of 33 GEOLOGY OF CHIPPEWA COUNTY MICHIGAN

The earliest comprehensive work on the geological formations in this county was done by Carl Rominger. He published his findings in volume 1 of the Geological Survey of Michigan in 1873. It appears from a careful reading of this report that Rominger visited practically every one of the isolated outcrops on the mainland portion of the county, and a good many of those located on the islands which belong to the county. He studied the shore line of Drummond Island, but does not record any observations made in the interior portion of the island. This seems unfortunate as the stratigraphic section from the top of the Engadine, through the Niagara and the Cataract, down to and well into the Richmond, is singularly well displayed almost layer for layer. With this section well in mind he would have been able to trace the various units of the section with more ease and accuracy. Thus he would have been able to avoid confusing the Engadine with the middle Manistique on p. 37 and 38 of the volume cited.
