Yellow leaves~Mellow Yellow for 092809

I struggled to find signs of fall yesterday for my Sunday Stills Challenge and instead, I had to dig through my archives. I mean, here in Southern California, fall really hasn't begun yet and here in the desert, it was 109 degrees yesterday and will be 106 today! But, up in our local mountains, I did see some aspen and birch trees and cottonwoods that had a few leaves turning yellow. Then, at the end of the day, I came upon this tree. I have no idea what kind of tree it is, but the sun was hitting its yellow leaves and they sparkled in the afternoon light. Mellow Yellow for Monday, September 28, 2009.
