The intended method of excavation in CA 73 Ext will be to break up soil using the pointed end of a pick axe. For strata that contain an abundance of material, soil will be removed in the trench using trowels and sorted while in the trench directly into buckets. If the amount of material is too great to pick axe, then trowels will be used to break up the soil. Depending on what is uncovered in CA 73, however, the methods of excavation may change.
A dirt dump for discarding all soil excavated from CA 73 ext. will be established 10 meters south of CA 73. Terra cotta roofing tiles and plaster will be counted by bowls. The bowls used for counting these artifacts have a diameter of 36cm and a maximum depth of 10cm.
Once tile and plaster have been counted they will be discarded in a tile dump, which is established three meters north of CA 73. Pottery and bone will becollected separately in latte boxes. Pottery and bone will be counted individually and brought down from the hill in latte boxes. Latte boxes have the approximate depth of 23cm, length of 9cm, and width of 6 cm.
For any special finds recovered from the trench, coordinates and
elevations will be taken. In order to determine the coordinates, a
plumb bob will be held over the location of the special find, and
then the distance from two of the perpendicular baulk walls will
be determined by extending a tape measure at a right angle from
the string of the plumb bob to the string marking the boundaries
of the trench. In order to determine the elevation of special finds,
once again a plumb bob will be held over the find spot of the special
find. Simultaneously, a string with a line level will be attached to a fixed
datum points and will be pulled taut and level, so that it intersects with
the string of the plumb bob. A tape measure will be held so that it runs
parallel to the string of the plumb bob, and the elevation relative to the
datum point may then be determined. Because CA 73 is being
s imultaneously excavated in open excavation with its neighboring
trenches the excavation methods will additionally be coordinated with
