Almost all of the leaves have fallen off one of my maple trees in my yard! It seems so early for one of my trees to be so bare. Has anyone else noticed odd trends in your region this autumn?

It seems that some of the trees are already starting to turn color likely given the stress they've been under due to the really hot and dry summer we had this year. At the GLOBE Program Office, we identified our phenology site last week and took our first Green-down measurement on a box elder tree. We're going back out today to take our next Green-down measurement. Is anyone else starting to see signs of autumn?
