You can walk for an hour through a forest of 47,000 trees in Utah and never once leave the same organism.
It's called Pando — Latin for I spread. A clonal quaking aspen in Fishlake National Forest, where every white trunk across 106 acres is genetically identical, sprouting from one continuous root system. At an estimated 6,000 tonnes it is the heaviest living thing we know of, around thirty blue whales.
Each visible trunk lives about 130 years. The roots underneath are somewhere between 9,000 and 80,000 years old, and nobody can narrow that further, because clones leave no rings to count.
So what looks like a crowd is one life quietly persisting, sending up new trunks again and again. Everything you can see of it is temporary. The old part was never above ground.
Some things don't just grow. They endure by becoming many.
