In Colorado’s Rocky Mountain National Park, the colors are starting to change above about 9,000 feet. I was unable to find any large expanses of yellow but did find some nice, isolated batches. I kind of like shots like this with the contrasting brilliant yellow of an Aspen tree and the deep blue skies of high altitude.
