Take a look at this photo. It's not super quality but something caught my eye. It was shot in 2003 on Minnetonka right at first ice. The ice is razor thin and the waters only a foot deep. But look close and you'll see tiny little air bubbles trapped in the ice that perfectly outline the rock that lies below it. Weird huh? What do you think would cause that?

I have no idea what would cause that but it is cool. I've never seen anything like that before.

I am guessing it's some cool physics coming into play here. Being simply a Yeti I wouldn't know where to start....

But the picture is further proof that just when you think you have seen it all in nature....someone has something new.

Thanks for pic!

That is a neat picture but I have never seen that before and could only guess why. Maybe sunlight heated the rocks.

[Deitz Dittrich]

If I had to guess, decayed algae on the rocks, and the bubbles are methane? Or some other gas from the decay?

I like DD's theory

[yakfisher]

I would guess the oxygen being produced by the algae, but I have no idea. You should have lit a match to see if it was methane

[Deitz Dittrich]

Dbl- I'll tell you right now, its never a good idea to agree with me. .I am wrong a lot! Its like that say, those that cant teach, teach PE. But I really think I am right on this one!

[Dbl]

Normally you would be correct, I would be hard pressed to agree with you but I do think you are correct on this one! Oh well always a first DD

I am wondering if maybe it was windy in the days before and maybe some small air bubbles were trapped in the algae on the rocks. Then as it calmed down the bubbles were released and got trapped.

Similar theory to the DD, but a bit different. Anyone's guess really.
