Jeff,

I looked at your VGF file, and it containes a single 0.01" contour value, which 
can be ambigous
if directional lines (DLINES) is not used.

I used your grphgd.tbl entries and added
DLINES=yes;yes|0.005
The result matches the plot of your desired output.

The filled contours here look slightly better with the hole in NY state if the 
lowset threshold is 
0.005 rather than 0.01 when a high resolution grid is used.
