The tree is still quite lively, and while memory fails me now, I believe it was some sort of hardwood...
The burl appears to be quite random, and chaotic. It makes me wonder what sort of wooden treasure is hidden inside of it.
I can only hope that the parks department, when this tree finally falls ill, or is knocked over by a storm, has the decency to honor this spectacular specimen by allowing this burl to be harvested and used for something beautiful.
I know it might seem silly, but I somewhat doubt I am the only one that gets giddy when presented with something this outstanding. Oddly enough, I bet most people would look at this tree and think how ugly it is... Too bad they don't see the inside!
