Skywatch Friday: Strange Things in the Pond
I volunteer at our local nature centers at least once every week. Last week I was at Fountain Creek and the view of the pond was different to what I've seen before.
What in the world is causing those round spots? I knew we didn't have bubblers out there to keep the water from freezing.
Just as I'm wondering about it our facilities manager walks in. He says this is caused by pockets of methane in the pond. Who knew?
