Pond circles. Another example of loving the mystery and not even trying to get at the actual answer.
Peggy Gervase near Buffalo NY spotted a series of circles in the ice/snow covering the pond. It looked like crop circles and she had not seen this happen before.
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.
It took me all of 3 minutes to find a better answer than “fish farts”.
When the ice first freezes it usually does so during a cold snap in calm conditions. In many cases the bulk of the water is not really as cold as it should be to sustain a frozen surface. In this case there will often be holes from a few feet to a few tens of feet in dimension that do not freeze over until several hours to a couple of weeks after the main ice sheet forms. These areas probably stay open because of convection currents set up in the water by the large difference between the surface temp of the water under the ice and the water exposed to the very cold air above the holes. They often stay open for days or weeks because early season cold snaps are often followed by a period above freezing weather.
Exactly what happens at the end of winter up north. News report fail. They could have had their fun but at least given the answer. People really believe kooky stuff.
