2002 TRENCH PC 24
Ashley Bennett, Field Supervisor
Reports from the end of the field season
of Trench PC 24, Ashley Bennett.
As PC 24 was opened only
five excavation days ago, we are just now beginning to get a
feel for what this trench may have to offer us, and things are
getting exciting. With the closing of PF 11, and our great move
to the top of Poggio Colla at the site of the monumental building,
we have all spent this first week adjusting to the differences
between the two sites. First off I would like to welcome Meg
Common to our excavation team, and to mention the loss of Joe
Cosentino to PF 9 in the FOD where he will finish the rest of
the season. In addition to this, not only are the physical aspects
of excavating each place very different; dealing with heat, plow
zone, and rock hard dirt in the FOD, as opposed to the shade,
tree stumps and multiple strata that we are now facing, but the
two contexts are dramatically different. We have gone from excavating
what we thought to be the exterior space of a ceramic production
site and possible habitation, to excavating what may be the exterior
space of a known monumental building with three distinct building

As the foundation walls
of the building on Poggio Colla are further excavated with each
season, the purpose of PC 24 is to explore the south side of
this building. In previous years, PC 1 revealed a Phase III south
wall running parallel to the primary south foundation wall, also
Phase III. This raised many questions as to the function of this
second wall that have yet to be answered. In addition, last season
Justin Winkler, in PC 22, found that his south wall of the monumental
building made a strange curve to the north and seemingly connected
to a sort of wall spur running in a southerly direction from
it in his extreme south-west corner. These two facts were the
primary reasons for the placement and excavation of PC 24. Located
directly south of PC 17, our 5m x 5m trench hopefully will help
us to discern the function of this second south wall, and the
space within it. The most probable theories are that it was either
a terracing wall associated with the third phase of the monumental
building, or that possibly we have another structure entirely,
of which the second wall found in PC 1 is actually the north

So, with all of these
questions to answer, we have already begun to peel back our second
stratum in PC 24. With time working against us, we are currently
excavating only Loci 1 and 4. Our first stratum being humus,
it is within this second stratum that we should begin to see
the tops of any walls if they exist in this location. It is also
where we are starting to see evidence of burnt ceramics, eroded
roof tiles, and even some small pieces of amorphous metal slag.

These first few days,
however, have been spent battling the numerous roots that weave
their way through the top levels of this stratum, as well as
dealing with the delicate issue of extracting two gigantic tree
stumps, one of which was sitting precariously in our west scarp.
I must give full credit to my assistant, Kirk Nickel, for working
nearly eight hours straight to accomplish this feat. Bravo! Yet
again patience is proving to be a great virtue, and judging by
the increasing number of artifacts and suggestive stones at the
bottom of this pass, it will surely pay off.

As Thursday comes to
a close, we are all still drying out from the torrential downpour
that greeted us on site Monday morning. Both students and the
trenches alike were soaked through and through, and it has taken
all week for everything to dry out. Due to this unfortunate weather,
excavation moved very slowly and ceased early several days this
week. PC 24, however, was very lucky, in that the rain did not
greatly affect the actual trench, meaning stratigraphy and scarps
were left unharmed. Other trenches were not as lucky.

Once we did get moving
again on Wednesday, we finished our pass through Level 1 of our
Stratum 2, and got started on the next pass through Level 2 of
Stratum 2. While the first pass yielded only minimal burnt ceramic
sherds, along with some tile inclusions and a few sparse black
glaze pieces, we did uncover the top of some large stones. Those
became our main focus, and as we continue this second pass we
have found that these blocks do indeed sit on top of others.
While nothing is definite as of yet, this certainly indicates
great potential for a wall structure. Additionally, while keeping
our eyes out for a stratum change, I noticed that the soil in
our northeast corner seemed to have a much more red appearance
and was yielding a great deal of large coarseware and tile fragments.
If we do find a wall, this could be evidence of wall packing,
but at this point our elevation is still too high to tell. The
completion of this pass, and the beginning of the next will help
to answer some of these questions.

I can hardly believe
it, but sadly it is true that our excavation season is coming
to a close. This is especially disheartening to those of us in
PC 24 because our trench was begun much later than the others,
after we excavated PF 11. However, despite the shorter excavation
period, I still feel like we have accomplished a lot and answered
many questions. At the current moment we are working on our first
pass through Stratum 3, in one of our Loci, Locus 1. Stratum
3 is our first real archeological level and corresponds with
the Phase 3 building construction. I have chosen to limit excavation
to this area because I feel that this will get us to a good stopping
point by the end of the season. What we have found already in
Stratum 3 has insured that this trench will be reopened next
year. We have ascertained that there is a wall structure running
north-south along our west scarp, and we are currently excavating
what appears to be a type of floor or terrace packing within
Stratum 3. This is made even more exciting, as there are portions
of large coarseware vessels within this packing. If we are lucky,
we may have at least a full profile to reconstruct. With three
more excavation days left, I plan on finishing out one more pass
within Stratum 3. While there is still much work to be done here,
it gives us something to look forward to for next year.

As the season is officially
at an end and the backfill is in the trench, it is time for us
to sit back and reflect on what we have learned from PC 24, and
what new questions it has created. At the closing of excavation
for the year we had successfully finished our first pass through
Stratum 3, our first contextual level. It was within this pass
that we were able to define what appears to be a N-S foundation
wall, a portion of which is visible along our west scarp. I believe
the rest of the wall sits to the west of PC 24. There are several
interesting features of this construction that are worth mentioning.
The first is the large rectangular stone in the extreme north
corner, which may be the same stone we see in PC 22, extending
from the Phase III E-W wall, to the south. Further excavation
is required to prove this, but that would make the two walls
contemporary. The rubble packing construction technique already
appears to be Phase III.

The second point of interest
is the gap in the stones near the midpoint of our two loci. There
is a distance of approximately 50.0cm where there is no visible
foundation stone. It is possible that it merely exists at a lower
elevation; however, there is no evidence of this. Additionally,
I believe several of the stones immediately to the south of this
gap are floating and have simply decayed into a sandstone block
making them appear to be in situ. If they are indeed floating,
and were removed, this would widen the gap to a distance of 70.0cm.
This is a substantial distance and could be accounted for if
a stone was robbed-out for re-use in a later construction. However,
we know of no later phase than the one we believe this wall to
be part of, Phase III. Another explanation may be that this was
a threshold into an interior space to the west. A slight change
in stratigraphy was noted in this area, as there were several
chunks of grey clay-like soil, as well as a general darkening
of the soil near this gap. This is often evidence of a highly
Trench PC 24 from the north at the end of the 2002 season.
The last interesting
feature of the wall is the fact that it does not continue all
the way to our south scarp. Again we may be dealing with a missing
stone, a stone at a lower elevation, an unfinished construction,
or potentially a corner. If there is a structure to the exterior
of the main building, this foundation wall, as I believe it to
be, could be the first evidence of it. Excavation to the west
of PC 24 seems to be the next logical step and will help answer
this question. More of the wall-like structure could be exposed,
and stratigraphy could be analyzed on one side versus the other,
looking for evidence of interior space as opposed to exterior

Aside from the wall-like
structure, we have found an interesting stratum associated with
it. Stratum 3, which lies at approximately the same elevation,
is full of many broken vessels, both fineware and coarseware,
as well as many roof tile fragments, large and small. These areas
of inclusion are oddly concentrated in certain areas of the trench
while the rest of the trench has substantially fewer artifacts.
I believe this to be a packing level, commonly associated with
Phase III at Poggio Colla, which was created to fill and stabilize
the area around walls, as well as to level the overlying floor.
The same thing was found in PC 17 immediately to the north. Unfortunately,
we have no evidence of a floor level here, as it would have eroded
away quickly once the building fell into disuse. There is actually
no evidence at this relatively shallow elevation to suggest that
this is interior space.

At this point in time
I am very excited about the wall structure we have found, and
I am anxious to continue excavation of this trench next season.
Hopefully, we will find more clues as to the relationship of
this area to the monumental building, as well as the function
of our wall structure. There is a lot to think about in the following
months, enough to keep us all busy, I am sure.
