The site was divided into 5 areas:
Area A. This area is defined by an old stream channel to the north & east, by the paved road on the west, and by the edge of recent bulldozing on the south. This southern boundary will be indistinguishable with time but probably influenced the locating and mapping of flake scatters during August. The area measures 60 meters (N-S) by 100 meters (E-W). This is the area recorded by Kikuchi as a concentration of flakes and cores in February 1988 when the area was recently bulldozed and cleared of surface vegetation.
Area B. Located to the east of Area A, and defined by the old stream channel to the west, the base of the ridge to the north, and a dirt road to the south and west. Kikuchi identified this as an area of flake scatter in February 1988. The area measures 140 meters (N-S) by 60 meters (E-W).
Area C. This area to the south of Area A is recently bulldozed and without any ground cover in August 1988. The area is defined by Uhau Iole Stream on the west, a dirt road on the south, and the old streambed with a low ridge to the east. The area measures 120 meters (N-S) by 80 meters (E-W).
Area D. Located to the south of Area C, this area is also recently bulldozed and defined by Uhau Iole Stream on the west and south and by a low ridge on the east with Eucalyptus trees. The area measures 80 meters (N-S) by 200 meters (E-W)
Area E. Located to the east of Area d, this area has been recently bulldozed and is defined by Uhau Iole Stream on the east and south, the base of the ridge of the north, and the low tree ridge to the west separating Areas D and E. The area measures 140 meters (N-S) by 120 meters (E-E) and has two alluvial terraces where Uhau Iole Stream turns to the north.
Upon completion of the survey and mapping, two test pits were excavated to determine if there was any depth to the adze materials or if it is just a surface scatter. These test pits were excavated by trowel and materials were screened with a 1/4 inch mesh. The flake and artifact materials were collected during the excavation of these test pits. The materials collected and the areas sampled have been inventoried. A total sample of over 2300 basalt pieces was collected from the surface scatters and test pits. The sample represents a range of material types and artifact forms.
Test Pit 1 was located in the northwestern quadrant of Area C in an area with a flake concentration (C-1) and which had been recently bulldozed so it was clear of vegetation. The unit was one meter by one meter and oriented MN. The unit is sloping and the upper 3-5 cm is loose and powdery. Both of these factors appear to be the result of recent bulldozing activity.
The stratigraphic profile for Test Pit 1 was as follows:
Test Pit 2 was was located near the center of Area A to examine the concentration of flakes and cores noted by Dr. Kikuchi in February, 1988. The ground cover vegetation is now established in this area and DOFAW had inquired about mowing the area. Therefore, the testing was to determine if there was any depth of the flake scatters in Area A and to determine the sensitivity of the area to such activities as mowing. This test pit was also a one meter by one meter excavation unit oriented MN and located in the northeastern quadrant of Area A ...
The stratigraphic profile for Test Pit 2 was limited to one layer with a charcoal-lined pit feature as follows:
0-18 cm 10YR3/4 (dark yellowish brown); clayey silt; crumb to blocky structure; sticky and plastic; several waterworn boulders noted at surface to 10 cm below surface; charcoal flecks and few basalt flakes. Feature 1 A charcoal-lined pit feature partially exposed in the north wall of the unit. The charcoal averages 3 cm in thickness and the fill is mottled charcoal and reddish clay. The feature is generally circular in plan-view, at least 40 cm in diameter. The feature extended from 4 to 11 cm below surface. Probable firepit feature.
Preliminary Findings: The predominance of basalt flakes and adze blanks/preforms supports the labeling of the site as an adze workshop. The general lack of finished adze forms suggest that this function was conducted elsewhere, perhaps along the Wailua coastline where the majority of the habitation is recorded in early historic times. Although the source for the adze materials has not been identified, several of the cores suggest that river cobbles may be one source and it appears likely that the source originates further upstream from site 4000.
There is a general lack of any other cultural materials associated with the basalt flakes and adze blanks/preforms. The only feature identified was the probable firepit in Test pit 2 which suggests that there may have been temporary occupation of the area while the adze materials were being worked. However, there was no surface indication of occupation areas or midden that would suggest semi-permanent habitation in the site area. The testing indicated a shallow depth to the adze materials.
The fairly high number (60) of blanks/preforms recovered from the 20 acres suggests that not all the preforms were being used or taken elsewhere to be finished. The survey of the Moana Kea adze Quarry also indicated a high number of rejected adze preforms and one suggestion has been that these preforms were the work of apprentices and not of adequate quality for finished adze production. Several of the blanks/preforms at Wailua were recorded as broken which probably occurred during manufacture.
