& the weather looks perfect<br/>
<br/>
but i would like to call it an unqualified class b even before trying<br/>
since i prefer to avoid minuses plusses effs etc<br/>
so as not to suggest or in any way resemble scholastic grading <br/>
& because class b is generally harder to do than class a anyway <br/>
& also because i am confident you will recover your cairn<br/>
& will measure carefully 80 feet east from the monument this <br/>
time & reinaugurate the cairn 55 feet west of its present location <br/>
before adding to it<br/>
so as to bag & commemorate the most plausible & best <br/>
currently available tripoint position<br/>
<br/>
in my experience the 40 foot fudge factor that is supposedly built <br/>
into usgs topos is only admitted by them so as to cover their ass <br/>
in the most extreme lapses & is thus usually way overstated<br/>
<br/>
in practice <br/>
things are normally nowheres near that unreliable<br/>
<br/>
& not to even bother considering the additional & possibly still <br/>
greater fudge factor that is often built into gps readings<br/>
<br/>
so i think in this case simply measuring the paper topo & the <br/>
horizontal plane above the sloping earth as faithfully as possible <br/>
will still represent the best available datum & the best available <br/>
tech all rolled up into one<br/>
<br/>
& if you simply lie down on the job & stretch out to your full length <br/>
along the ndsd parallel with your butt at the 80 foot mark <br/>
before you reset the cairn of course<br/>
you will in all probability be perfectly on point & perfectly class b</div>
