It survived -- being one of the few -- the 1906 Great Earthquake when many of its mates were cut down for survival needs, and is older than Golden Gate Park, which is 150 years old ... the park was built between the old oak stands to the north and south...
And hidden in plain sight. I discovered this place ONLY LAST YEAR, and literally thousands of people drive by a quarter-mile away EVERY DAY and never even know it is there!
(On the other hand, it's probably good that it is somewhat hidden -- that tree survived BECAUSE ...)
Yes, maybe it's a good idea to keep such places under cover. They've had problems on trails here when too many people show up for the clicks.
