Day
1
Today was the first
day of excavation at the Naval Stores, Kangaroo Point. It was a
cold morning in Brisbane and we were all rugged up for the 8:00am
start. The crew consisted of: Jon Prangnell, Tam Smith, Kevin Rains,
Alex Wisniowiecka, Griffith Young, Michelle Langley, Joanne Stewart,
Anastasia Carter, Margaretha Vlahos and Julian Travaglia.
The first task of the
day was to document the site before any digging could commence.
Our excavation area measures 2.0 x 2.5m, and is situated next to
the remaining foundations of Naval Stores 1. The area selected for
excavation was overlain with a bitumen surface. Before this was
removed, we had to set up our site datum, which is a fixed reference
point from which all the measurements on the dig are taken. We also
recorded the features of the site by drawing the area on our recording
forms, and taking photographs. Keeping records of an excavation
is very important, because as you dig you actually destroy the site
as you go.
The method of excavation
that we decided to employ is a "horizontal excavation",
removing each excavation unit across the site, opening up the whole
area at once. Our first excavation unit at the Naval Stores was
the bitumen surface. After we had mapped out the dimensions of this
first unit, the Brisbane City Council workers had to remove it.
Using heavy machinery, the bitumen was cut into small squares and
carefully taken off the surface, exposing our second excavation
unit.
Our second excavation
unit was a very compacted surface, probably put down before the
bitumen was laid. It was a hard concrete-like matrix, pale yellow
in color, and composed mostly of small-to-medium sized rocks. This
surface was very hard to dig through, and the trowels were soon
discarded in favour of small hand picks, which made the work somewhat
easier. There were only a small number of artefacts recovered from
the site today, and included some small pieces of glass (window
pane and bottle), a bullet casing, and a small piece of metal.
Throughout the day there
was a lot of interest from the public as they walked, cycled, and
roller-bladed past the excavation on the Kangaroo Point Boardwalk.
Many of them talked to us about what we were doing and were able
to watch as we worked. We felt that it was a very productive day,
as we excavated down about 25cm, and the crew worked very well together.
