P90428Redwoods are SO TALL!
How tall are they?
They are so tall that you can see for yourself if you look in this direction . . . from anywhere in North America or Central America.
They are so tall that if you need firewood, I can aim one in your direction as I cut it down.
They are so tall that while they drop foliar debris on the Ford and Chevrolet parked below, they also drop foliar debris on Mercury and Saturn in their respective orbits.
They are so tall that while other trees collect kites and Frisbees, they collect airplanes.
They are so tall that only a few of their seed survive. Most burn up in the atmosphere on their way down.
They are SO BIG too!
How big are they?
They are so big that some have tunnels cut through them so cards don’t run out of gasoline while driving around.
Okay enough of that for now.
Most of the biggest redwoods here were harvested, leaving only stumps to remind us of how big they were. The few trees that were big enough for harvest a century ago, but were not harvested when those around them were, probably exhibited some sort of defect that made their lumber undesirable.
The tree in this picture happens to be one of the few that is big enough now to suggest that it was likely big enough for harvest when those around it were harvested. The trunk is more that six feet wide. Yet, except for the severe lean, no obvious defects were observed. (The vertical edge of the doorway to the left was included in the picture for comparison with the lean of the tree.)
The tree started to lean only recently. If it had taken several years to develop this lean, the top several feet of the trunk would be curved upward, as it would have continued to grow vertically away from gravity while the trunk below it moved. If it moved suddenly but only once several years ago, there would be a kink near the top of the otherwise leaning trunk, from which, subsequent growth would be vertical.
This tree instead leans with a straight trunk from bottom to top, which means that it grew vertically, and then moved into this diagonal position too recently for new vertical growth to develop. Lateral branches are also diagonal, as they maintained their position perpendicular to the trunk. Although redwoods rarely destabilize, this one really seems as if it is about to fall.
Is this destabilization relative to some sort of deficiency that prevented the tree from getting harvested a century ago? I really should investigate.
