1-x-1 meter grid unit 1504N 1769E.
Southwest quarter of the site.
Located in the south-central portion of Nonstructure 105, roughly 7.5 m south of pit structure (Structure 106).

Random. Third 1-x1-m unit selected for excavation in Nonstructure 105.

Natural strata.

Undisturbed native sediment. Excavation continued approximately 5 cm into undisturbed native sediment to confirm the sterility of the deposit. Excavation was terminated at roughly 84.50 m.

Random. First 1-x1-m unit selected for excavation in Nonstructure 105.

Natural strata.

Undisturbed native sediment. Excavation was terminated at approximately 84.57 m. A 15 cm x 15 cm window was dug into the northeast corner of the unit to confirm sterility; the bottom of this window was at an elevation of 84.47 m.

15

1-x-1 meter grid unit 1510N 1773E.
Near the center of the site.
Located in the northeast portion of what was originally thought to be Nonstructure 105 but what proved upon excavation to be a different study unit (Nonstructure 112). Located roughly 2 m southeast of the pit structure (Structure 106).

Random. Fifth 1-x1-m unit selected for excavation in Nonstructure 105. Upon excavation, this unit was assigned a different study unit (Nonstructure 112).

Natural strata.

Undisturbed native sediment. Excavation was terminated at approximately 84.68 m. A 15 cm x 15 cm window was dug into the northwest corner of the unit to confirm sterility; the bottom of this window was at an elevation of 84.59 m.
