The stratigraphy of the middle Devonian Traverse group of parts of Presque Isle and Cheboygan counties is described. The scattered outcrops are correlated in part with the better known section in northeastern Michigan, which includes southeastern Presque Isle and eastern Alpena County, and in part with northwestern Michigan which includes Emmett and Charlevoix counties. Reliance is placed principally on correlation of faunal zones for those relatively thick alternating limestone and shale subdivisions, such as the Genshaw and Gravel Point formations of the Traverse group. Sharp lithologic breaks between other subdivisions which, between their upper and lower boundaries, are characterized by uniformity in composition and texture, also are useful in correlation. The discrep ncy in total thickness between the Traverse of the described area and the Traverse sections of the east and west is emphasized, and diastrophism suggested as the cause. Three new stratigraphic names, Koehler limestone, Gorbut (a member of the Gravel Point), and Beebe School formation, are defined and described. The writers use their stratigraphic divisions in making a structural contour map of the area, which shows two anticlines, one north of Onaway, and a second, west of Afton.
