The trench will be excavated stratigraphically using big pickaxes, hand pickaxes, trowels and brushes. The small end of the pickaxes (big and small) will be used to loosen soil which will then be hand sorted using trowels into buckets, any finds being removed as they appear. These buckets will then be dumped on the dirt pile approximately 15m north of T-70. If material finds dictate that the use of the large pick is too destructive, then hand picks and trowels will be utilized.
Terracotta roofing tile fragments and plaster will be counted by bowls (the bowl used has a diameter of 28cm and a maximum depth of 8cm), which will be counted in terms of how full this bowl is. It will then be distributed to the terracotta pile utilized in 2013 CA trenches, approximately
20m west of T-70. Any bulk ceramic or bone finds will be counted individually on site and collected in bulk finds within latte boxes which will be brought to the magazzino at the end of every day to be dry brushed and categorized at a later date. Finds recovered during the cleaning and trimming of baulk walls will be collected and organized separately from contextualized materials.
Special finds will be recorded with regards to their coordinate on the master grid on site, as well as their elevation. A plumb bob will be used to mark the location of each find and a known datum point (marked by string used with a line level) dedicated to the trench's use will be used to find elevation, the trench's grid coordinates used to calculate the find's coordinates.
The datum for T-70 is 27.57 Absolute Elevation (AE). These finds will be drawn onsite and then sent to the magazzino for cleaning, further analysis and possible cataloguing.
Each trench has been laid out on the master grid across site. Due to an error in the calculation in 2014 (by 43cm) there is a 30cm overlap between T-70 and T-69 in the south. This area will not be excavated unless T-70 reaches the same elevation, in which case the entire trench will be declared a new locus and lowered concurrently.
Any changes in soil type, composition, material or rock clusters will be observed and noted in the trench book. Then, if warranted, a new locus will be declared with materials recovered associated specifically with that location within all documentation processes.
It is important to note that ultimately the composition and stratigraphy of the trench will dictate the method of excavation and thus the method may change.
Records will be kept by Matilda Stevens.
