<div id="ygrps-yiv-984375913">yes a beer for me too<br/>
but because 645a is more than a second south of 644<br/>
i find it hard to visualize so much northering as you see<br/>
& certainly not in the middle of the lake<br/>

&gt; &gt; such an averaging will produce a tripoint position of<br/>
&gt; &gt; nad27 45d00m38s3775 x 73d20m40s036<br/>
&gt; &gt; which tho probably unreliable beyond tenths of a second<br/>
&gt; &gt; still seems far more credible than the usgs positioning<br/>
&gt; &gt; which incidentally has the additional defect <br/>
&gt; &gt; of placing the tripoint north of both monuments<br/>
&gt; &gt; yikes<br/>
&gt; &gt; for how could that be true<br/>
&gt; &gt; <br/>
&gt; &gt; while neither position is terribly punctilious<br/>
&gt; &gt; they both still afford target areas of about 10 foot circles<br/>
&gt; &gt; whose centers are more than 100 feet apart </span></blockquote></div>
