my ongoing try for a first arizona tricounty point visit class a
has settled on & continues to focus on maricopa county because of her relatively high population density & development level & the relative accessibility of her corners
 
but after a virtual perambulation & closer look at all her tripoints on topozone i have to report that any apparent or presumptive advantages she may have had have actually not born any monumental fruit at all yet & dont look like they necessarily will
 
 
of lamaya you already know the most likely particulars
 
& traveling from there clockwise or eastbound along maya to the gila tripoint at gimaya 
thru the continuous or discontinuous sequence of 30 numbered corner markers 
of which quite a few are missing from the topo as number 2 was but may still be recovered too
i find gimaya is depicted as the unmarked trijunction of a ridge line convergent on giya & the continuous maya & gima geodetic convergents that fall between maya marker 30 & gima marker 31 
evidently of the same continuous original series begun at lamaya
 
of course gimaya might be marked by a corner marker number 30a that isnt shown on the topo
but if so that remains to be demonstrated
 
 
next continuing along gima comes pinal 
so thats gimapi 
or maybe i should say eccentrically gimapin to distinguish her from pima who is coming next 
yikes
but again 
this one too is depicted as unmarked
 
 
pima comes next continuing along mapi 
so thats mapipi 
yikes 
or mapimpin 
yikes again 
& tho i dont know which name is worse
fortunately she is not far from kaka 
which gives a little cover
 
& this one too is shown as unmarked 
tho her location does offer hope of a public land survey corner pin
 
in fact the only maricopa tricounty hope i have found for class a
 
 
continuing west along mapim to yuma county
mapiyu or mapimyu is reached
& the atwood 113d20m long line is regained 
but no marker is shown
 
 
worse yet 
the freakin corner isnt flush but appears to jog significantly
oops
but i will get back to that after i close the perambulation
by simply continuing north now along mayu to lamayu
where again no marker is shown
& finally looping the loop by following lama from there to lamaya
 
 
now
the 113d20m atwood line from which i began & along which i have also closed the perambulation
& which is supposed to have been run continuously in 1918 from the santa maria river to the mexican border does not in fact appear have been marked that way 
if the sequence of 51 markers running north from near mapimyu thru lamayu to near lamaya are its production
a detail which i cant yet verify
since these could of course be a later series too
 
but there are no markers at all shown by usgs anywhere along pimyu
the southernmost leg of the 113d20m atwood line
 
not at the mapimyu point & jog 
& not even at the mexican border
 
 
& how the heck did that jog creep in there anyway 
if all this is supposed to be so rigorously atwoodian
 
did he himself introduce it
 
indeed is there any evidence that he himself set anything more than an initial rock at 34 lat 
& that anything else we find on his line is his actual doing
 
i havent found any yet
 
 
so anyway
i dont know where to continue on to from here
but if anyone notices a hotter tricounty marker prospect anywhere in arizona than has been identified at mapimpin aka kaka 
my last maricopa chance if any
would they please let me know
 
or bag it themselves
 
 
thanx & beeps
