WHERE DID THE SALT COME FROM UNDER LAKE ERIE?

The salt under Lake Erie primarily comes from ancient evaporite deposits formed during the Paleozoic era, around 400 million years ago, when the region was covered by a shallow sea. As the sea gradually evaporated, it left behind layers of salt and other minerals. Over time, geological processes buried these deposits beneath sediment and rock, creating the salt formations that are now found beneath the lake.
