me too
as there are several difficulties here beyond my ability to resolve

first
tho i did get a good look at your excellent report last night
the confluence page seems to have seized up this morning
so i cant get back to it now to double check the data
tho i trust it will soon be restored

but in any case
when it was working
i was able to copy these nad83 coords for the 1909 disk
as presented on the 1998 tablet
nlat 48d59s57s110
wlong 117d01m56s715

& tho the bcidwa monument does appear to be situated near the
middle of the clearcut & therefore nearly smack dab on caus
these coords dont compare well to the nad83 coords for the
neighboring markers published by the ibc

namely
marker 196 to the east
nlat 48d59m57s6
wlong 116d59m28s0
& marker 195 to the west
nlat 48d59m57s2
wlong 117d01m43s6

if all 3 sets of coords are correctly stated
the bcidwa marker would lie some distance west of 195
yikes
as well as about 30 feet south of the clearcut
yikes again

so something is clearly & seriously out of whack there

but maybe i should wait til you get the report on line again
so i can at least compare your gps readings to these coords
just to get an idea which ones might be off

in any event
forgetting the coords for the moment
& based on your pix & descriptions alone
it certainly looks like at least class c
