Three tones of soil temporarily excavated
from Hyde Park
Between 21 March – 9 June, 201
Northern side of Hyde Park, adjacent to
College Street
The soil that has been removed from the site at Hyde Park
has been temporarily relocated and placed within the installation on
Waremah (Cockatoo Island) where it will remain until Monday, 9 June 2014,
after which time it will be returned to the park. This process of removal shows
the profile of the soil in the exact location, revealing the layers of history
within the park’s soil structure. The hole is accessible for viewing 24 hours a
day.
Thankyou to Professor Stephen Cattle, Dr
Damien Woods, Dr Lisa Murry, Guy Stearn, Patrick Houlcroft and Michael Abbott
for assistance with this process.
Sign at the site of the hole in Hyde Park:
The soil that has been removed from this
site has been temporarily relocated and placed within an
exhibition in building 6 on Cockatoo Island. It will remain there until
June 9th 2014, after which time it will be returned to this
void.
The process of removal shows the profile of the soil
in this exact location. At the top of the
profile is the loamy top-dressing from recent landscaping
activity related to the park as it exists “now”. This park
did not always exist. There was a time when it was non-existent as either
a concept or a physical space. In its place stood a stand of dry
sclerophyll forest, the clearing of which began upon invasion in 1788. The
park now persists as one expression of a larger process
of annexation that continues into the present moment.
Below the top layer of soil, at the depth of
about 40cm, rests a thick layer of fill composed of clay peds with rubble and
shards of bluestone, broken brick, charcoal, bones, fragments of crockery,
pieces of coke and broken glass. This material arrived from unknown sources into
the park over decades of excavation and building in other parts of Sydney
during an earlier phase of urbanisation. The pockets of clay within this
mixture are most likely derived from the massive excavation that occurred
within this park during the Great Depression, which involved the digging of the
City Circle underground rail tunnel in 1922.
Below that, beginning at the depth of approximately
1 meter, sits a luscious layer of clay, shrouded in total
darkness until this most recent excavation. This clay was
derived from a part of a small lens of Ashfield Shale rock, one of
the Winamatta group of shales that formed in
the Middle Triassic period of the Mesozoic era –
around 220-240 million years ago. In that layer is embedded the remnants
of tiny root fragments of the vegetation that flourished and
perished during that period.
I would like to acknowledge and pay
respect to the traditional owners of the land on which this project occurs –
the Gadigal people of the Eora Nation. It is upon their ancestral lands that
this park is constructed.
Thankyou to Professor Stephen Cattle
and Dr Damien Field of the University of Sydney
for their assistance with making core samples of the soil prior to
this dig, as well as to the generous sharing of their
knowledge and ideas. Thanks also to city historian Dr Lisa Murray for
advice and assistance in accessing the City of Sydney archives.
