The sea level contour in the Imperial Valley misses the tripoint between the<br/>
California counties of Imperial, Riverside, and San Diego by about 100 meters.<br/>
The elevation of the tripoint is +16 feet.<br/>
<br/>
The MXUS boundary drops below sea level as it crosses the Imperial Valley, but<br/>
no American county or Mexican municipio boundaries intersect it there.  Neither<br/>
are there any municipio tripoints in the Laguna Salada depression just to the<br/>
south, which is Mexico&#39;s lowest point at -10 meters.<br/>
<br/>
There are no county boundaries at all below sea level in the Death Valley<br/>
depression.<br/>

&gt; I thought also about Baarle - the boundary cross.  I<br/>
&gt; was hoping maybe this might be below sea level.  But,<br/>
&gt; <a rel="nofollow" target="_blank" href="http://fjtraining.wldillon.com/altguide.htm">http://fjtraining.wldillon.com/altguide.htm</a> has<br/>
&gt; Baarle-Hertog at + 26 m.  Don&#39;t know what the<br/>
&gt; elevation is at the binational quadripoint, but 26<br/>
&gt; seems like too much to overcome.  But it is certainly<br/>
&gt; lower than Sorgschrofen!  And Cooch Behar boundary<br/>
&gt; cross?  Cooch Behar airport elevation reported at +<br/>
&gt; 136 feet (41 m)<br/>

&gt; (but where is the quadripoint in realtion to this?). </span></blockquote></div>
