Metal in the wall of the cemetery may have
masked subsurface magnetic anomalies close
to the walls, but the results of this survey
shows several locations for further
investigation.
Within the cemetery walls, numerous small
bipolar anomalies could represent unmarked
burials. The GPR profile at locations A, B,
and C illustrates the hyperbolic nature of
the GPR reflections in the central portion
of the cemetery.
Fill material on the road to the west of the
cemetery, as shown in the GPR profile at
location D, may cover and distort anomalies
from prior burials.
Hyperbolic reflections in the GPR profiles
performed north of the cemetery may
represent burials at a depth of
approximately 0.8m, as illustrated at
location E.
