A San Andreas Fault Pine Tree Survives Massive Earthquakes and a Lightning Strike

The Navitat Wrightwood property is full of unique stories and history.   One story we think is especially cool is the story of a magnificent tree that rests at the base of our property only a few hundred feet away from the San Andreas Fault. (The fault line runs right across the front edge our our property!)

This handsome Jeffrey pine that we’ve dubbed “Old Andy” is a true testament to the strength and stability of trees. According to the local forest service, this particular tree survived the Southern California earthquake of 1812 registering a magnitude of 7.5 and then the  earthquake of 1857 registering a 7.9!  WOW!

“How do they know the tree was in the earthquake so long ago?” you may be thinking. Well, they measure ring widths under a binocular microscope using a dial caliper and examine all significant departures from normal growth trends and interpret them taking all possible environmental factors into account during a given year.  Btw, for those of you that aren’t into math, this means that “Old Andy” is well over 200 years old! And he’s got the scars to prove it!!

After hearing of “Old Andy’s” determined longevity and strength maybe you will feel even more secure to know that the Navitat course is ENTIRELY tree-based.  (click here to learn how Navitat is different from other canopy tours) The trees are the supporting structure for our zipline cables and our platforms.  Not only that, but we do everything we can to minimize our impact on these trees! We use growth blocks to separate the cables from the trees. (no tree stranglers here, just tree huggers) We also have Arborists come to our property and check the health of the trees periodically.  Uh-huh, that’s right. We CARE about these trees! They are our livelihood here at Navitat, so it makes sense that we would want to treat them with the utmost care and respect. Plus, they’re beautiful.
