| Geologic factors | ND | ND | Actual area; ST | ND |
* applied 300 ft square around center point f
cemetery.
** applied 100 ft square around enter point of cemetery.
*** coal It 14 in. not included in original resource estimate.
**** applied only to underground mining within 200 ft of the
surface.
***** applied only to coed beds lying totally in the subsurface
and
only accessible by shaft
NB = no effect, factor may be present but not considered to be
restrictive due to local practices
ND = no data or insufficient data
ST = statistics were applicable where data were insufficient to
map the factor.
None = none in quadrangle.
It = less than gt = greater than
