NBC NATIONAL NEWS — An Oklahoma man has uncovered a mystery of sorts at the bottom of dried up Lake Hefner.
Dan Cross was walking the lake bottom of his old fishing hole this weekend when he came across a concrete cylinder sticking up out of the mud.
On the top of the concrete, three names were engraved; John Mitchell, Dick Thomas and Paul Wood and the date July 25, 1958.
"It's just like a note in a bottle to me. It'd be like if the lake ever dropped, if the levels ever dropped to this point again, they'll find our names," Cross said.
Lake Hefner started filling with water in 1947, but didn't have enough water to float boats until the year 1958.
Carl Borgfeld, with The Friends of Lake Hefner, said the three names etched into the concrete did not come up in any of the history of the lake.
He guessed the names may belong to construction workers who built the concrete water break nearby, or that it was possibly someone's boat anchor.
"It's possible that it's set here for all this time and is just now being discovered," Borgfeld said.
Cross is eager to uncover the story behind the stone and is curious to see if the men who left that message at the bottom of the lake are still around.
"That's 53 years ago so they would be however old they were to do it and then add that to it, so they're pretty old," Cross said.
