This image was on July 3, 2019. Not surprisingly, considering that there are raindrops on the lens, it was raining at Glacier National Park. The clouds over the distant mountains are so thick that the mountains can’t be seen. There is a great deal of gold near the lake from aspens and larches, though the temperatures didn’t start getting hot yet and the nights haven’t been crisp enough for the leaves to change color.
This is actually an illusion. The trees are the same color as those in the foreground, but sunlight is shining through the clouds and directly onto that swath of trees, making them appear yellowish-green because of contrast and lighting.
