<div id="ygrps-yiv-1753951066">given the unusually low stature above ground of the 48 inch long stone post <br/>
pictured in the attachment<br/>
any significant upheaval of it by the tree seems unlikely to have occurred <br/>
in the past<br/>
<br/>
& given its 10x10 inch girth<br/>
any cross fracture of it in the course of its displacement by the tree also <br/>
seems implausible<br/>
tho admittedly not inconceivable<br/>
say if the base had been wedged in bedrock or between larger rocks while the <br/>
upper part of the post rested in loam<br/>
etc<br/>
so i am guessing the entire post remains unbroken<br/>
despite the enormous & possibly even conflicting stresses it is under<br/>
<br/>
by contrast<br/>
the familiar upheaval & cracking of paving slabs by trees<br/>
is i think owing to their comparatively broad thin crackerlike shapes<br/>
& to their typically more friable materials as well<br/>
& i think especially to the fact that their displacements are resisted only <br/>
by gravity & thin air<br/>
