Tomorrow is the 111 year anniversary of the Great 1906 Earthquake. Everyone knows about all the damage in San Francisco, however, up here on the North Coast we had some major damage also. The ridge line I live on is 5 miles from the San Andreas fault. We are on the side that is not moving North.
Logging of the huge redwoods had been going on for about 40 years and what was taken first was all the low hanging fruit. All of the "perfect" trees were cut and the logger's left a bunch of big trees that weren't worth taking at the time. Of course after the quake pretty much all the big trees were taken for the rebuilding of the city. However, there are a dozen or so big trees around here that I have found while hiking and riding that are quite interesting. They all were broken about 100 feet or so up and have branched out over the years. These trees are 8-10 feet at the butt and there is one I've found that is 14 feet. We call it the BFT. I just figured that they were broken when they were falling trees in the area. Well, truth be known, they were broken/snapped from the force of the quake.
As the fault comes back inland around 10 miles north of here there is a redwood stump on the fault that was sheared in half from the fault movement. There is 20 feet distance between the stump halves. We have a trail that we ride that crisscross' the fault and the landscape totally changes on the fault line. It's kind of spooky.
So, a little local history lesson today.
