One solo backpacking/flyfishing trip, off-trail, I came into a grove of extremely old Juniper Ceders on a slope, heading to a lake to fish. 8-10' bases and around 20' tall, looking half dead. I found the coordinates on my map (well before gps toys) and stopped by the hi-country ranger station on the way home. She looked at me, frowned, and said, "Oh, you found them". Ok, yea, so... Evidently it is one of those kinda of secret groves of very old trees on the west slope of the Sierras. 3000-4000 yrs old according to the ranger. They had done core samples. Pretty darn cool.
