Eden, NY (WGRZ) -- A mystery of sorts has unfolded in Peggy Gervase's back yard.
As she looked out from the deck of her home on Friday, Peggy spotted what appeared to be a series of concentric circles that had opened in the snow covering a nearby pond. It almost resembled the unusual phenomena known as crop circles. But again, this occurred on the surface of a pond.
Gervase posted pictures on Facebook and with a link on the WGRZ Facebook page, there were nearly 40,000 views with more than 200 comments. They contained explanations of what may have caused it. They included everything from underground springs to melting ice, meteors, methane gas, gas expelled by fish and ducks, and -- of course -- aliens.
Gervase told WGRZ she did not see any strange lights in the skies that night and for now, the pond circles remain a mystery.
