You are probably correct.  I would not expect any bedrock at all in this<br/>
location--not within the range of tree roots anyway, much less within the range<br/>
of monuments.<br/>

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