Glacier's role in milk production

One of the artifacts in the village of Aurora starts high up on the plateau, which makes up Ledyard, Venice Center and Genoa. Today, we call it a gully, but it was a small river 15,000 years ago when the last glacier melted and retreated north to its origins. The slopes on which we live today, were once sheer cliffs leading up to the plateau. As the ice melted on top of the glacier, the runoff into the Cayuga Lake basin cut down through the cliffs and slopes like a hot knife through butter.
