Ohio produces three billion dollars worth of natural gas and $844 million of oil annually. Coal deposits were first recognized in the 1740s by early settlers and were mapped as early as 1752. Decreased demand due to increased natural gas production has reduced coal mining in the 2010s, although one underground mine and three surface mines ...

The region has gently rolling moraine hills left over from the retreating glaciers, as well as small sandy ridges, which were formed as coastal dunes during periods in which Lake Erie was higher than it is today (14,000-12,000 years ago).
Lake Monongahela was a proglacial lake in western Pennsylvania, West Virginia, and Ohio.It formed during the Pre-Illinoian ice epoch when the retreat of the ice sheet northwards blocked the drainage of these valleys to the north.

In its advance to the Union City Moraine, the glacier crossed terrain free of ice except for a few scattered blocks northwest of Alexandria, but from Alexandria to eastern Delaware County it probably overrode thin debris-charged stagnant ice. Gravel-filled channels in the dead ice mass were not destroyed by the overriding glacier, but a veneer ...
