World's oldest tree turns 4,847

World's oldest tree turns 4,847 this year and is in a top-secret location: Even if people have laid eyes on the world's oldest tree, there's a good chance they didn't realize it. That's because the United States Forest Service keeps all information about the 4,847-year-old Great Basin bristlecone pine — including its exact location — completely under wraps to protect it from any potential vandals, loggers, and researchers who may be interested in chopping it down.
