Fifty years ago, if you had arrived at the natural tunnel in Bennett Spring State Park, you would have seen a lake. Around 1964, a dam created from gravel and silt and reinforced with rebar and concrete blocked the upstream entrance of the natural tunnel. There is no record of how long the resulting lake lasted, but historical accounts state the dam failed after heavy rains, leaving only the portion of the structure seen today at the end of the trail. Walk the Natural Tunnel Trail today and imagine what it would have been like 50 years ago.
