I am inspired by big, old trees. Even though I have not been lucky enough to see them in person, my imagination is captivated by the giant redwoods and coastal redwoods. Giant sequoias live at high elevations, enduring cold, heavy snows, lightning strikes—and growing bulky and strong, though not so tall as coast redwoods. This individual, the President, is the second most massive tree known on Earth. This photo is from the Dec. 2012 issue of National Geographic Magazine.
