OKLAHOMA CITY -- After the water level dropped at Lake Hefner, a mysterious rock formation was discovered in the sand.
Fisherman Mike Fair said, "I noticed it last year when the lake was this low. I just came out one day and walked right by it, right through it, and there it was."
A viewer sent News Channel 4 photos of the mysterious rocks on the bottom of the lake.
One person said it looked like a crop circle underneath the water.
All the rocks are strategically placed and appear to be an image.
Steve Stovall with Rees Associates said, "It's a scissor-tailed flycatcher”.
Stovall works on the third floor of the Rees Plaza in the East Wharf on Lake Hefner.
The architects design buildings and apparently like to window watch.
Stovall said, "We look out our window and we see people out there wandering around looking at the rocks and trying to figure it out because it doesn't look as cool down there as it does from this high."
Last Summer when the water level dropped, Stovall and his co-workers drew up the blueprints for the large scissor-tailed flycatcher made out of stone.
It is so large that it can be spotted on Google Earth.
Stovall said it was a fun project to get people talking and attract a little attention.
