Hi Byron
As far as I can tell, you could create a negative sized buffer from the
extent of the primary geologic dataset (use square and mitre results,
not rounded, for buffering), then clip the primary dataset using the
negative buffer to remove the unwanted zero contours.
Cheers.

i have a large geologic dataset that i want to grid and contour.
There is an irregular zero edge that bounds these data on one side and
a straight bounding area edge on the other sides. If i create an
irregular polygon that encloses these data, is there a way to grid and
contour such that these data are truncated against the polygon and do
not extend beyond? --
