Appraisal Methods
and Excavated Surface
The
methodological approach we chose was function of strategic and logistic
settings. It consisted in the following choices of procedures and
appraisal techniques (Tab. 2):

procedures applied to document monument B3.
The
following figure gives an overview of the excavated surface in relation to
the main structural remains (Fig. 11). An illustration of
the surface we excavated in 1999 can be found in our preliminary report (Blumer
and Vial 1999: 241). Due to the limited time, we decided not to set up a
complex system of quadrangular sections, but to develop the excavation
surface by adding irregular sections, which enabled us to follow specific
archaeological questions progressively. Another difficulty in arranging
the sections was due to the temperament of our fieldworkers, who were not
always eager to follow straight lines! Since they were all novices in this
kind of work, we preferred to give them a certain amount of freedom
instead of directing them too strongly. At least end, no archaeological
data was lost and the goals were reached, and this shows the viability of
our strategic choices in organizing the excavation.
Fig. 11 gives also the precise
location of the stratigraphic cuts we made and documented. Two cuts (Cut 3
and Cut 4) are located at some distance from the main excavation area and
are thus not placed on this map.

In
each newly opened section, the following methodological procedure was
applied: (1) removal of debris and sediment accumulated during recent
terracing work (shovels), (2) excavation of soil layers covering
structural remains or anthropic deposits (trowels), (3) excavation of
anthropic deposits around structural remains (trowels), (4) surface
documentation of structural remains (scale drawings and/or digital and
positive color photographs, altitude measurements).
In
the some sections, the surface obtained showed clear accumulations of
collapsed structural elements. In such case, and at specifically chosen
locations, we removed the collapsed elements after proper surface
documentation, in order to access and document the base of the anthropic
structures. The removed stones were piled at specific spots: near square
N98 for the western outer wall and near square U3 for the cut through the
eastern outer wall.
The
excavation of the platform chamber filling necessitated the numbering of
the surface stones belonging to the collapsed chamber roof. An individual
number reported on the 1:10 scale surface drawings marked all concerned
stones. At campaigns end, the numbered stones were stored under a plastic
sheet in the area of square A5.
The
archaeological material was collected with individual three-dimensional
coordinates, so we can replace each artifact in its initial sedimentary
and structural context.

Blumer, Luc Braillard, and Colette Gremaud did all drawings of structural
remains of monument B3. Blumer and Braillard shot all photographs.
