yes indeed the curvature of the earth wreaks havoc with the grids
& we have similar corrections all over the usa
only they are smaller & fewer here because of our lower latitudes
but i am staggered to have learned in the meantime the true
cause of the staggersteps
thanx to the same association of manitoba land surveyors
who were professing total ignorance as recently as last year
from their
http://www.amls.ca
site comes the following new data
the original manitoba of 1873 was so small it was called the
postage stamp province
& a campaign to expand its bounds continued thru the 1870s
a first minor adjustment
which took into account the township lines in the realignment of
the western boundary
was granted in 1877
the change occurred after the land survey was completed
when it was discovered that the original border actually
dissected farm holdings in the margins of the province
the new boundary was moved a few miles west to the nearest
township lines
& this accounts for the jagged appearance of the western border
of the province
well at least this is the beginning of an explanation
but it really only accounts for the first few stairsteps north of caus
within the original mb postage stamp
which occupied just the lower left 16th of mb today
later mb additions & mbsk survey continuations created more
stairsteps well into the 20th century
presumably by the same process
all the way north even beyond flin flon
til they finally stopped when the 102nd meridian was reached
at about or exactly the 56th parallel
i guess by then the border delineation & demarcation had
outdistanced the township creation in northward progression
