The First Season of Archaeology at Indiana...Part 2

Excavation in the East Field [Image 5] |
The East Field [Image 5]: Three
excavation units in this area
resulted in the recovery of hundreds
of 19th century artifacts -
providing comparative material
for the analysis of two more
house lots in the town. A wide
range of ceramic decorative types
along with container glass, smoking
pipes, architectural items, and
personal objects (glass marbles
and a moulded glass dog’s head,
for example) were some of the
more interesting finds recovered.

The Grist Mill: A primary objective
of the work this summer was
to investigate one of the industrial
buildings that was central to
the town’s economy. The location
of David Thompson’s grist mill,
completed in 1835, was determined by scaling off
the 1844 plan of the town upon which this structure
was depicted. As a testament to the skill of the 19th
century cartographer, the accuracy of the plan was
confirmed when the modern positioning
corresponded precisely
with a cut in the hillside [Image 6]
(where the slope had been terraced
for the second storey), remnants
of a masonry wall, and a
scatter of loose limestone rubble
on the ground surface.
Subsequent excavation in this area
revealed the presence of two interior
walls and the recovery of
mostly architectural debris and
several large pieces of hardware
and machinery components.
These artifacts require further
analysis but it is clear at this point
that additional excavation in the
mill will provide information on
the technology employed and,
perhaps more importantly, changes
in mill technology through time.

Rockfall in the millrace from the wheelpit and west foundation [Image 7] |
Another excavation trench, positioned
to crosscut the millrace,
revealed a layer of rockfall, presumably from the millrace walls and the west foundation
of the building [Image 7]. This rockfall was
buried below a metre of modern flood deposits which
had probably accumulated since 1975 when a significant
flooding episode occurred along the Grand
River. Some idea of the scale of flooding in the past
was witnessed during the field school as, over a single
weekend, the one metre deep trench (1 x 8 metres
long) was completely filled with water as the river
level rose almost 1.6 metres, completely inundating
the trench and filling the adjacent canal and millrace!
[IMAGE 8] Further excavation in two year’s time will
be conducted in an attempt to define the original
wheelpit and possibly the pit for the ‘Leffel’ or
‘Vulcan’ turbine thought to have been put into the
mill in 1883 by David Thompson.
