  2. Teays River - Wikipedia

    en.wikipedia.org/wiki/Teays_River

    The River's headwaters were near Blowing Rock, North Carolina; it then flowed through Virginia, West Virginia, Ohio, Indiana, and Illinois. (Hansen, 1995). [ 4 ] The largest tributary to the Teays River was the Old Kentucky River (Teller 1991), which extended from southern Kentucky through Frankfort and subsequently flowed northeast, meeting ...

  3. Lake Monongahela - Wikipedia

    en.wikipedia.org/wiki/Lake_Monongahela

    [1] Marine (1997) found five terrace levels along the rivers, but he had to conclude that the lake deposits found on them resulted from only two episodes of glacial damming. Deposits on the fifth and fourth terrace levels represent damming during a pre-Illinoian glaciation, whereas the third- and second-terrace-level deposits represent damming ...

  4. Till plain - Wikipedia

    en.wikipedia.org/wiki/Till_plain

    Till plains are an extensive flat plain of glacial till that forms when a sheet of ice becomes detached from the main body of a glacier and melts in place, depositing the sediments it carried. Ground moraines are formed with melts out of the glacier in irregular heaps, forming rolling hills.

  5. Lake Tight - Wikipedia

    en.wikipedia.org/wiki/Lake_Tight

    The river's path traveled through modern-day West Virginia, Kentucky, Ohio, Indiana, and Illinois, finally emptying into the Gulf of Mexico, which at the time extended to southern Illinois. The glaciers of the Ice Age soon began to block the Teays, effectively damming the river and forming Lake Tight, near what is now Chillicothe, Ohio.

  6. Glacial till plains (Ohio) - Wikipedia

    en.wikipedia.org/wiki/Glacial_till_plains_(Ohio)

    Since glacial till is highly fertile soil, agriculture on the glacial till plains is very productive. 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).

  7. Valparaiso Moraine - Wikipedia

    The inner border is less than 15 miles (24 km) and at its closest approach is only about 6 miles (9.7 km) from Lake Michigan. The system is from 5 miles (8.0 km) or 6 miles (9.7 km) up to nearly [6] 20 miles (32 km). It is narrowest in LaPorte County, Indiana and widest in Lake County, Indiana. [7]

  8. Geology of Ohio - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Ohio

    Ohio's State Invertebrate Fossil, is a trilobite found in the formation. The Southern Hemisphere where Ohio was located at the end of the Ordovician experienced a widespread glaciation, around 438 million years ago. Sea level dropped due to the glaciation, accompanied by a subsidence of the land.

  9. Fluvioglacial landform - Wikipedia

    en.wikipedia.org/wiki/Fluvioglacial_landform

    Fluvio-glacial processes can occur on the surface and within the glacier. The deposits that happen within the glacier are revealed after the entire glacier melts or partially retreats. Fluvio-glacial landforms and erosional surfaces include: outwash plains, kames, kame terraces, kettle holes, eskers, varves, and proglacial lakes. [4]
