Here's something I bet you didn't know: 10,000 years ago Tonawanda and the surrounding areas were covered by a massive lake!

The lake was located on the south side of the Niagara Escarpment east of the current location of the Niagara River in between Early Lake Erie and a Glacial Lake Iroquois (which would become Lake Ontario) to the north.

The lake soon evaporated when the water levels of Lake Erie dropped below the level of the streams to the lake. Lake Erie then drained over the escarpment through Niagara Falls.

So next time you're in Tonawanda look around, at one point you were at the bottom of an ancient lake!
