good luck with this difficult search is all i can say unless you can deal with metadata in which case perhaps<br/>
<br/>

<br/>
but the mexican state maps & other infos at <a rel="nofollow" target="_blank" href="http://www.inegi.gob.mx">http://www.inegi.gob.mx</a><br/>
<br/>
may also help or lead you to better<br/>
<br/>
while there is also reason to hope that verbal descriptions of the state boundaries may be found in laws or constitutional amendments of 16jan1952 & 20&30jan1960<br/>
<br/>
but the best of good luck anyway because you are in practically virgin country there in any case in terms of boundary hunting & absolutely terra incognita insofar as we dont know for tripointing<br/>

<br/>
&gt; 	or so south of the USA line.<br/>
<br/>
&gt; <br/>
<br/>
&gt; 	The 1:50,000 scale maps of Mexico don&#39;t show this border.<br/>
<br/>
&gt; 	Larger scale maps do show a zigzag, straight lined border,<br/>
<br/>
&gt; 	at various locations. (differs on every map ??)<br/>
<br/>
&gt; <br/>
<br/>
&gt; 	For what it is worth, when driving dangerous highway 2 recently,<br/>
<br/>
&gt; 	the border was marked at the continental divide.<br/>
