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?

Who made mysterious rectangular tree holes?

rectangular holes in reddish tree trunkThe Question: I found these holes in a single tree, amidst dense forest. They were freshly made, with no sign of human footprints (there was snow), but no animal tracks either. They look very man-made, but could not have been. They appeared in a 24 hour period. Could you shed any light on them please?
