First discovered in 1988, the meagre collection (12 pieces)
nonetheless consisted of a wide array of raw materials (at least 4
distinct types) and implements (a pice esquillŽe, 2 burin
fragments and a burin spall). At this time, no features had been
discovered.
Goals
We returned to conduct intensive testing of the site in order to verify the apparent
presence of an Arctic Small Tool tradition (ASTt) occupation, and obtain
a more meaningful sample, hopefully including datable materials).
During our stay, 11
square metres were excavated so as to encompass the most productive
of the 3 positive 1988 shovel test pits. As a result of our pragmatic
extensions of the grid, we appear to have fully excavated a small
activity area centered on an equally small combustion zone.
Stratigraphy
The stratigraphy was
quite simple and straightforward. The surface layer was dominated
mainly by lichens and mosses with some dwarf birch in Unit E and
adjacent to Unit B. Underlying this loose surface cover was a compact
root mat with a thin layer of humus at its base. It is within this thin
humus that most of the artifacts were found. The following level is
considered the basal terrace surface and consists of a medium sand in
which occasional large stones were found.
The only
deviations from this stratigraphic succession was a frost crack
described below, and sand lensing which occurred in proximity to the
dwarf birch thickets mentioned earlier. These thin, yet distinct
layers
of fine sand appear to have accumulated near what amount to wind breaks
and suggest a period of localized aeolian activity.
Features
The central combustion zone is
characterized by a more-or-less circular area of fire-reddened sand
(diameter: 30 cm) with an associated,
sparse cluster of fire-cracked rocks. No faunal remains were found.
Charcoal was collected from the oxidized
sands. Although the sample consisted of only 1.9 gm of charcoal, a
radiocarbon date of 3470±430 B.P. (S-3377) was obtained.
A
possible post-mould was located less than a metre to the west of the
hearth area. In plan view, it was slightly oblong (10 cm x 15 cm) and
extended into the fine basal sand about 10 cm. The base of the dark
stain in profile was rounded.
The only other feature
uncovered in our testing was what appear to be a frost crack. This
narrow, linear feature had a U-shaped profile (10-15 cm below the
surface of the adjacent basal sands) and extended in direction, passing
through the hearth area. Lithic artifacts seemed to be more
concentrated within this feature, than in the surrounding areas,
especially in the southern half of Unit D.
Artifact Collection
The debitage collection is comprised of 698 pieces.
The variety of raw materials found in our excavations is even broader
than the range noted in 1988. There are a number of different
fine-grained cherts which were used (at least 6 varieties), along with
siliceous argillite, a coarse-grained metamorphic rock, and a
fine-grained, relatively soft stone which was not only chipped, but also
ground. The general size range of the debitage strongly suggests that
chipping activities at this site, or at least within the area we
sampled, were dominated by final tool preparation and tool resharpening.
The inventory of implements includes a complete spalled burin, 1 burin blank, 13
burin spalls made from a number of raw materials,
1 complete bipointed projectile
point, 9 microblades or microblade
fragments, 5 pices esquillŽes,
1 end scraper, 3 biface fragments and 2 retouched flakes.
This site, along with three others in the southwest Anderson Plain (NbTj-8,
NbTj-9 and MlTk-2), provided information which served as the basis for an
analysis of the Arctic Small Tool tradition in the region.
