Calaveras Big Tree State Park is about 4000 feet above sea level (lots of ear-popping on the drive) and home to some amazing, enormous trees. They can be up to 3000 years old and 300 feet tall. The largest one in this grove survives only as a stump (it was felled in 1832)--but what a stump: over 30 feet in diameter! Some of the names carved into it from early visitors are dated in the mid-1800s. Really incredible.
