Tunnel Tree

I gotta share this picture. This tree was holed out from top to bottom...I don't know how, maybe from fire or from lightning or something, I'm sure if I had the tour guide it probably told me, but I never got that...but IT WAS STILL ALIVE!

I went inside it and took this picture where I could see all the way to the circular hole out of the top of the tree, but the second picture is the tree from the outside.

Yes, it's got branches with plenty of green needles. Crazy that a redwood could live that way. Apparently, the super thick bark protects them from burning in a fire, and when they don't burn too much, the healthy tree continues growing around the damaged parts. But this seems a little excessive don't you think?
