VANDALIA — The featured speaker at the October 22 dinner meeting of the Vandalia Lions Club was Dr. David Schmidt from the Department of Earth & Environmental Science at Wright State University. Dr. Schmidt discussed how local geology has influenced history of the Dayton area.
He cited a book published a century ago by August Foersto titled Introduction to Geology of Dayton and Vicinity. During the Ice Age, glaciers, up to one mile thick, covered the Northwestern two-thirds of Ohio. Then, after the glaciers and resulting seas receded, there was a period of weathering and erosion. This resulted in several different layers of bedrock formations. These formations were important to future developments.
Several Stone Quarries in the local area, especially near Fairborn and northeast of Centerville, produced stone building blocks used in canal locks, walls, and buildings as ready-mix concrete was not available yet. Much of the water flowing through channels left by the glaciers met at Dayton. This was important for transportation, but the Indians warned the people that the area frequently flooded, and it did. Creative minds figured out ways to channel some of the water past mill-wheels to power many industrial machines and Dayton became noted as an industrial hub. And, last but not least, the sand and gravel deposits left by the glaciers, seas, weathering , and erosion, resulted in the aquifer under the Dayton area, which is very important to attracting new industries to the area.
