I know that there have been a lot of posts from this fall in CO, but I was lucky to be in the area 2 weeks ago at the peak of the fall colors and it was just incredible. So here are a few from that trip (some with Sony a7 and some with Fuji X).
Very nice Fall captures. I notice, especially in photo #2 that water reflections always seem to have a deeper color saturation as if that half of the photo was taken with a polarizing filter. Can someone explain the physics of this phenomenon?

The reflection of unpolarized light from a still water surface will be partially polarized (especially if the angle of the reflection is close to 53 degrees), so if you use a polarizing filter over the whole image, the sky will be less polarized than its reflection from the water.

If my purpose is to capture the reflection from water, then I stay away from polarizers as they will tend to eliminate them (if you rotate to the right angle). So I am pretty sure that I didn't use a polarizer on that photo.
For reflecting water surfaces, the polarizer is useful if you want to eliminate or diminish that reflection. For example, if you have rocks underneath or even want to create a darker look in the water.
So it really depends what your intention is. Hope this helps.
Also, I am pretty sure I applied a vignette in PP, so that will darken the image on the edges.
