Thanks, I too am curious how old this tree is. I wanted to take my local natural resources teacher out there, but didn't get around to it--he was talking about teaching a field class where you get to go visit all the oldest and largest trees in California, might have to add this on to the list! I need to go back out there to see it, been a few years. I will definitely measure it when I do, just need to borrow some equipment. I will let you know when I have some numbers, and more photos.
