Last month, unusually high winds knocked down 15 giant sequoias in Yosemite. If you haven’t had a chance to see them in person, giant sequoias are big—like, warp-your-sense-of-scale and melt-your-brain big. Then, once you’ve taken in their size, they do the same thing with your sense of time, because an individual tree can survive thousands of years. Wars, plagues, fashion trends: Sequoias have lived through and outlasted them all. To last thousands of years, any sequoia has also endured hungry animals, diseases, fires, snowstorms, El Niño events, and years-long droughts, not to mention the opportunistic loggers of the 19th and 20th centuries.
