The tree in the photo above is pretty tall - so tall, in fact, that it used to be the tallest known tree in the world. Until people found other trees that are even taller. NPR's Robert Krulwich has a very neat post about the discovery of the world's tallest tree: http://www.npr.org/blogs/krulwich/2011/04/08/135206497/the-worlds-tallest-tree-is-hiding-somewhere-in-california
