From my surveying book, it says that State Plane systems usually use
lcc projection (instead of tmerc) when east-west extents are larger
than north-south. So, I assume that North Carolina uses LCC projection
with State Plane, right? I also assume that my friends Forest Service
map is a LCC projection, right?A quick check with EarthVision (TM, Dynamic Graphics, Inc.) shows that
North Carolina has one zone and that it is in the Lambert projection.
(Zone 3200, NAD 1927.)
Indeed, checking nad27:
# 3200: north carolina ---: nad27
<3200> proj=lcc a=6378206.4 es=.006768657997291094
lon_0=-79 lat_1=36d10 lat_2=34d20 lat_0=33d45
x_0=609601.2192024384 y_0=0

and for nad83:
# 3200: north carolina ---: nad83
<3200> proj=lcc a=6378137 es=.0066943800229
lon_0=-79 lat_1=36d10 lat_2=34d20 lat_0=33d45
