Introduction
The aft cargo hold has been the main focus of site investigations since the late
1980's. Following several years of litigation and permitting procedures, SJAEI
began an intrusive investigation in 1988. After an attempt to find a cargo hatch
failed, a hole was cut through the deck to gain access to the interior spaces
(Figure 19). Excavation continued in the same area in 1989. Material recovered
from the hold during the two year project provided the circumstantial evidence
to prove the Maple Leaf's identity. Following a two year hiatus on field work,
the entrance hole was re-excavated in 1991 to monitor interior conditions. It
was opened again in 1992 to take water samples for analysis (Cantelas
1992:13-36, 1993:14-17).
Previous work in the cargo hold created a sloping trench extending down from the
port side to the centerline of the vessel. It measured approximately eight feet
long and six feet deep. This trench provided a working space and starting point
for the 1993 investigation. A decision on the excavation's final direction was
made after considering research goals in conjunction with examining the
condition of the material in the trench walls.
The primary goal was the controlled recovery of packing containers and their
contents to interpret the material record of the Civil War as represented by
this site. It also provided the opportunity to study how the vessel was packed
which reflects the stevedoring practices used during the mid 19th-century.
Finally, the open space created inside the hull provided a chance to examine
interior construction. Examining material exposed in the walls revealed a high
artifact concentration in the southeast corner. Extending the excavation in this
direction, towards the bow and centerline of the ship, offered the best
possibility to answer research questions on material culture and ship
construction. The resulting field investigation generally proceeded on an
east/west line under the centerline of the ship.
The small hole SJAEI cut in the aft deck in 1988 was enlarged in 1989 to measure
approximately 8 feet long, athwart ship. Removing a deck beam from the center of
the narrow hole, created an opening 42 inches wide. The opening is the only
known entrance to the cargo hold and provided access in 1993. It is located
139.5 feet aft of the bow and begins at the centerline of the ship and extends
toward the port side (Figure 20).
