A 259 foot section of the Upper Devonian Kettle Point Formation in a cable-tool drilled well contains an almost complete section of the formation. Species of platform conodonts are found in a sequence which correlate with zones defined by Ziegler (1958, 1962) and indicate that almost the entire Upper Devonian section is present. Correlation with the standard Upper Devonian ammonoid zones is cited. The sequence is interpreted as representing deposition in a basin in which the water depth gradually increased.
