In 1887 Annie E. K. Bidwell named this huge oak after English botanist Sir Joseph Hooker. When it fell during a windstorm in 1977, it was estimated to be over a thousand years old - it was nearly a hundred feet tall and 29 feet in circumference eight feet from the ground. The largest branch measured 111 feet from trunk to tip - circumference of outside branches was nearly five hundred feet.
