A Record of Post-Glacial Climate in Northern Ohio

By Paul B. Sears


This paper reports the probable course of post-glacial forest succession in northern Ohio, as indicated by a study of fossil pollen deposited in the Bucyrus Bog. The object of the study has been to trace in greater detail than has yet been possible the course of climatic change since the end of the Wisconsin glaciation. The principle employed is one which has been used in numerous European studies since 1915. It consists of a tabulation of the percentages of pollen grains of each species found in successive levels of bog deposits, and deduction of the prevailing forest composition at each level from this data. From the forest composition conclusions as to climate are drawn
