On Wednesday, my friend Ann and I went up Lamoille Canyon in the Ruby Mountains for one last glimpse of fall. (We are supposed to have snow this weekend, and the morning temp today was 21.)
This year, we both agreed, there are way more red leaves than we usually see. Our quaking aspens are usually golden to orange, with red being the exception.
For a great explanation of why leaves turn red, see
"Fall weather conditions favoring formation of brilliant red autumn color are warm sunny days followed by cool nights. Much sugar is made in the leaves during the daytime, but cool nights prevent movement of sugar from the leaves. From the sugars trapped in the leaves the red pigment called anthocyanin is formed."
"The most vivid colors appear after a warm dry summer and early autumn rains which prevent early leaf fall. Drought conditions also favor red pigment formation."
We already have a dusting of snow on the mountain tops.
I took over 200 photos, so there will be more fall foliage images in the next few days.
