<div id="ygrps-yiv-1215300421">I imagine it&#39;s just statistical.  Out of 1039 monuments, one of them<br/>
was bound to be on the boundary.  I think the precise positions listed<br/>
were determined with DGPS, probably long after the markers were set.<br/>

&gt; Any opinion as to why Monument 490 is as accurate as it is with<br/>
respect to latitude?  I assume that monumentation of the 49th is as<br/>
varied as it is due to the limitations of older astronomical surveys,<br/>
etc.  Since &quot;once it&#39;s marked, it&#39;s marked&quot; is the general rule, is<br/>
fair to conclude that #490 was surveyed much more recently than most<br/>
of the other monuments?<br/>

&gt;   The &quot;49th parallel&quot; portion of theUS/Canada boundary<br/>
&gt;   is marked by 1039 monuments and crosses the 49th parallel 15 times,<br/>
&gt;   at locations between the following pairs of monuments<br/>
&gt; <br/>
&gt; <br/>
&gt;   Only one monument actually staddles the 49th parallel:<br/>
&gt; <br/>
&gt;   Monument 490   - N49°00&#39;00.00&quot;   W106°59&#39;06.45&quot; </span></blockquote></div>
