is an aerial view of the upper pilcomayo valley & parallel river <br/>
road in paraguay<br/>
so argentina is in the foreground<br/>
& with any luck arbopy & a bit of bolivia are within frame at left<br/>
but the emphasis here is on luck & wishful thinking <br/>
& i make no claim of a true sighting but only of an exhaustive try <br/>
made over a period of several years<br/>
& a resultant best guess & hope<br/>
<br/>
a search of the relevant ibs numbers did identify both the arbo & <br/>
arpy convergents as true thalweg borders<br/>
& it even cited the intersection of this thalweg with a particular <br/>
integral degminsec of longitude as the actual tripoint position<br/>
but such a definition seems doubtful because the geodesic arby <br/>
convergent is not meridional & is marked by pillars including a <br/>
terminal marker on the left bank<br/>
<br/>
so if the claim is literally & precisely true <br/>
it would have required another rare triple coincidence <br/>
much like the one just actually observed at brcove<br/>
<br/>
so i doubt it<br/>
<br/>
but anyway the tripoint must be close to that exact degminsec<br/>
<br/>
<br/>
my search included a visit with the interesting people who live in <br/>
the area<br/>
the wichi indians<br/>
particularly on the argentinian side at santa victoria este<br/>

<br/>
& from various clues i can also guess wildly at additional lucky <br/>
hits in a couple of the pix of the river shown here<br/>

but for now please consider them all very probably class e<br/>
or i would just be pretending to you</div>
