What is the gold sheen on the water?

On some still ponds in an area  which was used for military training during WW2 and then became a clay pigeon shoot, a gold sheen appears during the summer months. It disappears when disturbed only to re-appear if left alone. I have not seen it anywhere else.  It could be that material was buried here at the end of the war which could provide a special environment due to leakage, of, for example, phosphorous, which I know was used to make anti-tank bombs. I suspect a micro organism of some sort but what?

What are these bubbles all over the lake?

bubbles on a lakeThe Question: In early June, I took a kayak trip on Winton Lake, starting out before sunrise and getting to the area where these photos were taken just as the sun was coming up. There were green bubbles all over the lake. After the sun came up, they began to break up and were gone within about an hour after sunrise. I’ve never seen anything like this on any lake I’ve ever paddled and I’m very curious what could cause it! Can you supply any answers?

Why does the snow melt in circles around trees?

trees with melted snowThe Question: Why do my trees have a clear area of snow around them when it warms up a bit. Are they warm? Do they give off or absorb heat? The clear area is anywhere from one to three feet around the base of the tree.

Who is this green frog and beetle?

The Question: I noticed this little frog stuck to the outside of my exterior door about 11 p.m. The porch light was on and was attracting various “bugs” which I assume the frog was taking a keen interest in. I saw the frog jump from the door to this position next to the bug, which I assume looked like dinner? Anyway, what kind of frog and bug is this?
