In one warm sunny spot below the south face of a massive outcrop of Sherman granite, the trees were still in their green summer garb.
Some aspen were sporting a few orange leaves ... maybe they made enough sugars during our warm fall days to produce some anthocyanins. Or maybe it really was the Leaf Fairies, the ones who go out on frosty nights and paint over dying leaves with these lovely colors.
Fall colors are not limited to trees. Around a bend in the trail I found alum root basking in the sunshine, its autumn leaves backlit by the low autumn light.
