Recently I lent a hand at removing some dead limbs from a white ash tree. The trunk on the tree is in the 48 inch diameter range - and when I counted growth rings in the 20 inch diameter limb which was removed - the limb had been up in the sky defying gravity for 125+ years!
Pretty amazing.
After the wood was on the ground, we cut it up for firewood. The image above shows spectacular "quilting" (also known as " curly" wood grain). Notice the bark also demonstrates quilting. More images soon. You can read about this corrugated type of grain structure - which also occurs in maple - here on wikipedia [1], and be sure to clink on the link to chatoyancy [2] -
The image above was illuminated with an LED flashlight - poor color rendition. I will try again with sunlight later.
White ash has a serious disease (ash yellows) which caused the die back on the tree. [3]
