Tetons
The drive from Yellowstone to the Grand Tetons was almost more exciting than visiting the Tetons themselves. Of course, this is an exaggeration but you don't generally have high photographic anticipation on your way to one of the most photogenic mountain peaks in the world. The turning of the aspen leaves and vivid cloud formations helped.
While a circular polarizing filter can really enhance the color of the aspen leaves, the polarizer can cause excess darkening of the blue sky at the top of the frame. The trick is to balance the amount of polarization of the aspen leaves with the blue sky.
