Open Context

Methodology

Methodology:

In CA 83, the standard method of excavation will be as follows. Dirt will be picked with the small end of a pickax, broken into clumps, and the clumps will then be hand sorted with trowels. In contextualized strata or loci (excluding topsoil), the sorted dirt will be counted by the bucketful, with soil from two out of every three buckets emptied into a wheelbarrow and then taken to a dump site approximately 20 meters to the southeast of the trench, overlying trench CB 52, but with soil from one out of every three buckets dry sieved using a sieve with a 1 centimeter gauge. Additionally, a wet sieve, with a gauge of 1-2 millimeters, may be added at a later point in the season; if this occurs, two out of every four buckets will be emptied into the wheelbarrow, one out of every four buckets dry sieved using a sieve with a 1 centimeter gauge, and one out of every four buckets wet sieved using a sieve with a 1-2 millimeter gauge.

Should any features, architectural or otherwise, require special care in excavating, such as a tile packing or a floor surface, trowels and handpicks may be used to excavate.

Any terracotta roofing tile found will be counted in bowls with an approximate diameter of 30 centimeters and a maximum depth of 15 centimeters. Once counted and recorded, these finds shall be discarded in a dump located to the north of trench CA 70 (2012), approximately 10 meters away. Any pottery or bone found will be counted on site and brought down to the magazzino in latte boxes for cleaning and further study. Any tile found while sieving will be documented separately but discarded at the end of the work day, while any pottery or bone recovered from the sieve will be brought to the magazinno and documented separately.

If any special finds are discovered, their coordinates and elevations in relation to the absolute elevation of the site shall be taken and recorded. A plumb bob will be held over the find and the distance from the trench boundaries will be measured at a right angle in order to determine the north-south and east-west coordinates. A plumb bob will also be held over the find in order to obtain its elevation when a string, affixed to a datum with the known elevation of 27.97 meters in relation to the origin, with a line level attached, will be extended over the find, intersecting with the plumb bob line. The elevation will then be measured with a tape measure. Special finds are then sketched in the trench book on site and sent to the magazzino at the end of the day for cleaning, analysis, and possibly cataloging. Any special finds found in the sieve will be designated supplemental finds and the

closest approximate range of coordinates and elevations will be provided.

Excavation will be conducted stratigraphically, so close attention will be paid to the soil being dug throughout the duration of the excavation in CA 83. Any changes in soil type will be noted in the trench book and a new locus will be defined, measured, photographed, aerial photographed, and recorded. Additionally, the baulk walls will be trimmed periodically in order to gain a better understanding of the stratigraphy. Any architectural features will also be given their own locus. Most trenches excavated in 2013 will be adjacent to one another, to better reveal any features that extend beyond the boundaries of a single trench.

Excavation methods may change throughout the course of the season, as the types and amounts of material found as well as the geology and topography of the trench ultimately determine the best excavation method.

Editorial Note

Open Context editors work with data contributors to annotate datasets to shared vocabularies, ontologies, and other standards using 'Linked Open Data' (LOD) methods.

The annotations presented above approximate some of the meaning in this contributed data record to concepts defined in shared standards. These annotations are provided to help make datasets easier to understand and use with other datasets.
