No prize for the first to identify it, just my lasting admiration.
The biggest of these trees are 3000 years old, saplings when David took down Goliath. How big are they? A better question might be, “how small are you?”
Imagine the biggest tree near you. A really big one, like a 200-year-old oak or an especially wide sycamore. Then take a Ken doll or a Barbie doll and put it down next to it. That’s you next to a giant sequoia.
