thanx good question
algatn upon nickajack can be visited twice
b o t h 
on terra firma 
on a shoulder of nickajack mountain
where there is a loose & possibly original 1818 rock upon which 
only a crudely chiseled tee junction can still be discerned
a n d
on the surface of the underground part of nickajack lake 
in the huge nickajack cavern that practically fills this hollow 
mountain
& which was indeed prehallowed in 1795 as the site of the 
chickamauga extinction
hence its notoriety & subsequent selection as the tripoint 
location
& is one algatn any truer than the other
i dont think so
but i dont even know if the gps works underground
for the upper dry algatn
see for example jacks book at the corner corner link
& for the nether wet algatn
well why spoil the fun of the chase here either
so i commend you all to a google image search of the 
underworld 
on the single word nickajack
where you will find the maps & the mountain & the lake & the 
normally gated cavern entrance & even a batman trypointer in a 
canoe in the dark inside the cavern
