On this trip to the pools I played with my polarizer a bit to get different looks at the same scene.
I’ve always found the polarizer an important bit of gear for most of my photography. It has an effect that can’t be duplicated with post processing software and with a little practice and experience, you can produce big changes.
Overhead and under water
And with a little twist we get this –

Isn’t that great? Not only can we see down into the giant cup of tea that is a vernal pool, but those rocks just pop out. I really like both images and I hope this pool stays wet. It hasn’t rained in a while (unusual here in northern Wisconsin) so who knows, but I think the area in the back of the image does stay full to some extent. There is a lot of peat moss back there in addition to the grass, so I think it does.
Here’s a view I quite like of the other pool I’m keeping an eye on.

The downed trees are so great. I imagine turtles basking in the sun, but I doubt it. Vernal pools don’t host those guys year round. Painted turtles need permanent bodies of water, like the Wisconsin and other lakes, ponds and flowages.
When I was there the ferns had just come up and by now must be unfurling. I’ll have to get back over!
Vernal pools are fascinating – love your photos. I recently learned that they are full of life, too! In our area (Virginia mountains), they contain so-called fairy shrimp. A naturalist, Brian LaFountain, made a gorgeous documentary about them.
Thanks for the nice comment. Yeah, vernal pools are teeming, aren’t they? Not sure if we have crustaceans in ours, but we certainly do in permanent bodies of water. I watch crayfish from my dock all the time!
