<div id="ygrps-yiv-929313192">oops yet again<br/>
as i got both the wrong book & author<br/>
for that map of the median line on lake michigan in message 2025<br/>
& sincerely apologize for the confusion<br/>
<br/>
instead it was probably from a 1940 book by s w boggs entitled<br/>
international boundaries<br/>
  a study of boundary functions & problems<br/>
<br/>
still seminal  i think<br/>
but irrelevant<br/>
<br/>

<blockquote><span title="qreply"> &gt;oops<br/>
&gt;i meant to say here the  michigan wisconsin  or  miwi  boundary<br/>
&gt;  rather than the  illinois michigan  or  ilmi  boundary<br/>
&gt;<br/>
&gt;m<br/>
&gt;<br/>
&gt;<br/>
&gt;ilmi has actually never been precisely delimited<br/>
&gt;& remains the least definite of all the interstate boundaries in the usa<br/>
&gt;a fact which obscures the ilmiwi & especially the ilinmi tripoint position<br/>
&gt;& makes the latter the most problematic of all the american tristate points<br/>
&gt;<br/>
&gt;<br/>
&gt;<br/>
&gt;&gt;<br/>
&gt;&gt;martin  this is a most major & indeed causal work  i believe<br/>
&gt;&gt;<br/>
&gt;&gt;for example<br/>
&gt;&gt;the following attachment copied from it shows the now familiar looking  but<br/>
&gt;&gt;in 1945 probably still seminal  depiction of a median line<br/>
&gt;&gt;<br/>
&gt;&gt;in this case it is the median line of lake michigan<br/>
&gt;&gt;probably selected by boggs because the illinois michigan interstate<br/>
&gt;&gt;boundary was actually under review for exact delimitation at that time<br/>
&gt;&gt;tho it had been defined loosely as the middle of lake michigan since 1837<br/>
&gt;&gt;<br/>
&gt;&gt;the fact that the subsequent final resolution of the ilmi boundary in 1948<br/>
&gt;&gt;didnt completely follow the boggs line but a somewhat simplified &<br/>
&gt;&gt;approximated equidistance line doesnt diminish the importance of what he<br/>
&gt;&gt;was putting forth here<br/>
&gt;&gt;<br/>
&gt;&gt;& today there may be as many special circumstances as ever to distract<br/>
&gt;&gt;boundary makers from following the truest possible lines of equidistance<br/>
&gt;&gt;   as recently seen for example at the courentyne mouth<br/>
&gt;&gt;     on the guyana suriname boundary<br/>
&gt;&gt;but the method demonstrated here by boggs perhaps for the first time is<br/>
&gt;&gt;today a basic principle & guiding beacon of the system of international<br/>
&gt;&gt;maritime law<br/>
&gt;&gt;otherwise undreamt of at the time he was offering it<br/>
&gt;&gt;   unless i am mistaken<br/>
&gt;&gt;<br/>
