English: A healthy joint would be more of a ball and socket of a primary and lesser solidly 'welded' as one, w/o a shear line between to separate as seen here from Hurricane Jeanne 2004 Lakeland, Fl. This joint has 2 competing primaries displacing each other.

. A> is only area usually seen outside the joint, this could look very sound for years unless eye knew what was sifting for. B>is ONLY cross wise /hold hold of fibers against joint spreading!!!!! C>is the ONLY vertical hold of fibers as pivot underneath load D>is the bark growing down inside the joint, as 'included bark' really guaranteeing no fibers grow across if get this. Would rather bark curdling out the top as tried to grow into joint for more of a signature that fibers were growing across and displacing the bark from growing into the joint. Bark pushing out top, not feeding deep into as shown; is signature of some crossing fiber support of better codom. Note how the shape of the fallen nor remaining wing are NOT round, and usually bear weight across the thin axis of each separate oval in the competing pair. .

Some despair how the tree could have failed us, but in the end looking at the bottom holding fiber as pivot and the very small, not very well placed connecting fibers (B), how did it hang on so long?? Should be the praise !
