- Glacial Till
Glacial till is unsorted sediment deposited directly by glacial ice. Glacial till is a soft rock identified by large angular rock fragments on the surface and within the soil. Because of their huge mass, ice sheets flow outward as if they were huge piles of peanut butter. As the ice moves, it pushes along soil, bedrock chunks, and other sediments and surface materials. Indeed, glaciers are extremely effective at eroding and transporting these materials and everything from clay- to boulder-sized particles are moved as one large mass. As a result, ground-up bedrock, plant fragments, and even animal remains can be found in glacial till. Glacial till can make excellent farmland. In fact, the great agricultural potential of the soils of the till-rich plains of western Ohio drew settlers to the area with hopes of becoming highly successful farmers. The glacial till located in the Bluffs area of Collins Run Creek was deposited approximately 24,000 years ago.
