MICH OHIO 



Fig. 8.9. Restored section of the Paleozoic rocks across the Allegheny basin and Cincinnati arch. 

 The line of cross section is shown on the inset map, but it continues across Ohio to the southern 

 Michigan line. After Tafferty, 1941, personal communication. The inset map shows the great 



Catskill delta and is taken from Barrell, in Schuchert's Historical Geology, 1924. The heavy lines 

 are isopachs in feet.
