<blockquote><span title="ireply"> &gt; While looking at a (low-resolution) map of Peru recently, I noticed that<br/>
&gt; it&#39;s northernmost point - at its border with Colombia, and very near the<br/>
&gt; Peru-Colombia-Equador tripoint - is on a river that&#39;s very close to the<br/>
&gt; Equator.  I&#39;m curious as to whether or not this is actually North of the<br/>
&gt; Equator.  Does anyone on this list know for sure?<br/>
<br/>
 </span></blockquote>Interesting bit of border. All the maps I have show the Peru-Colombia border<br/>
following the Putumayo River all the way to the tripoint, which is in the<br/>
Putumayo River near a Peruvian town called Güeppi. I&#39;ve attached a jpeg clip<br/>
from DeLorme&#39;s EarthA, which shows the relevant region around the tripoint.<br/>
That northward bend the Putumayo River takes just east of the tripoint<br/>
brings it pretty close to the Equator (the black horizontal line on the map)<br/>
but it doesn&#39;t reach it. The World DataBase gives the coordinates of the<br/>
northernmost point as Lat -0.032deg Lon -75.184deg.<br/>
The interesting bit started when I looked in Biger, who has a rather<br/>
different run for the border, albeit farther south. I&#39;ve attached a bmp scan<br/>
of his map. He describes this as the border following the Putumayo &quot;... to<br/>
its confluence with one of its tributaries, the Güeppi River. The boundary<br/>
line follows that river upstream westwards for about 25 miles (40km) and<br/>
meets the boundary junction with Ecuador northwest of the small Colombian<br/>
town of Cabo Reyes.&quot; This makes no sense in terms of the map, which shows<br/>
the border striking off overland and meeting the Güeppi at the tripoint.<br/>
This is compounded by the entry for the Colombia-Ecuador border which<br/>
states: &quot;The eastern terminus of the boundary is located on the the Güeppi<br/>
River, west of the small town of Cabo Minacho (Ecuador). It follows the<br/>
river downstream eastwards to its confluence with the Putumayo River ...&quot;<br/>
Taken together, these seem to imply that the two borders run alongside each<br/>
other in the Güeppi River between the tripoint (40km upstream) and the<br/>
confluence with the Putumayo (where most maps apparently plot the tripoint).<br/>
<br/>
So ... in answer to your question, I think that Peru doesn&#39;t extend north of<br/>
the Putumayo River, which doesn&#39;t go north of the equator along the<br/>
Colombia-Peruvian border. But beyond that I haven&#39;t the foggiest notion<br/>
where the border goes!<br/>
Anyone?<br/>
