Razor Cave is located in Southern Ontario in a riverbed near Lake Erie. The cave appears to take water in during the spring thaw. It's a tight squeeze and goes in around 15 feet. The surface of the interior of the cave is extremely sharpe, hence the name "Razor Cave". The bottom of the cave is compacted branches and is not far from the lake, and not much above the water table. Does it meet up with a flooded underwater passage connected directly to the lake???
