http://home.wi.rr.com/sanbornstrees/sumer limb drop/
The limb in the pictures is from a white ash. Property belongs to the mother of one of the people I subcontract to.
Limb was approximately 14m up, 11cm dia and 4.6m long.
Top 2cm shearded off near clean the rest peeled off.
No defects in the sheared area were noticable on the ground portion or the aerial stub (which got
lost in the jungle below, no pics of it.) With the exception of a small patch of whiter wood, that
resisted probing with a steel tool, somewhat visable in the sheared face JPG.
Limb drop occured aproximately 2 am on a calm night in the high 80s, daytime temps have been in
the mid-high 90's. Pictures were taken approximately 15 hours after limb drop.
IMO the visual data seem to support the theory of ray cell collaps being a major factor in SLD.
