Climate and Geology
The Ohio River is a climatic transition area as its water runs along the periphery of the humid subtropical climate and humid continental climate thereby being inhabited by fauna and flora of both climates.
The Ohio River is young from a geologic standpoint. The river formed on a piecemeal basis beginning between 2.5 and 3 million years ago. The earliest Ice Ages occurred at this time and dammed portions of north flowing rivers. The Teays River was the largest of these rivers, and the modern Ohio River flows within segments of the ancient Teays. The ancient rivers were rearranged or consumed by glaciers and lakes.
The vineyard soils of the Ohio River Valley are diverse, being on the boundary between glaciated and non-glaciated.

Famous quotes containing the word climate:
“Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
—Anton Pavlovich Chekhov (1860–1904)
