Lime Ridge Oak - Walnut Creek, California

Walnut Creek is surrounded by several open-space ranges and they're brilliantly emerald green thanks to a few rain storms in the past month (another one on the way, but not enough, unfortunately, to mitigate California's current drought). This one oak has managed to avoid annihilation as a sapling by roaming herds of cattle. It stands alone. I admire its twisty branch formations.
