WLD_CASEFILE
This value refers to the serialized case file number for each

CO-030-338
WLD_NAME
This value refers to the offical name of the wilderness. For
example: Gunnision Gorge.
WLD_STATE
This value refers to the administrative State for the wilderness.

Item Definitions:
WLD_DEF_FEATURE
This value refers to the natural, manmade, or mapping feature that
represents the Wilderness boundary. This value is recorded on each arc.
For example, if a portion of the Wilderness boundary follows a stream, the
def_feature would be stream, if following a contour line , the
def_feature would be contour, etc. If the def_feature was not used
when digitizing or updating this theme this field should be blank.
WLD_COORD_SOURCE
This value refers to the actual source of the defining feature.
It is the digital map source of the original arc that makes up the
Wilderness boundary. For example , if a portion of the boundary is a contour
line and the line was digitized from a 24K USGS Quadrangle the
coord_source would be USGS 24K QUAD.
