Site 52, Unit 3

Site 52

Group 3

Unit 3 was chosen for excavation based on the pres- ences of a number of large, apparently, unaltered boulders. The unit was located 20 m to the west (at 285 degrees) of Unit 2. Unit 3 was 1.5 m x 3 m and orientated 60 degrees North. The unit abutted a large boulder at the east end and ran between two large boulders to the north and south. The colour of the matrix on the surface of Unit 1 is 10R 4/3 weak red. After the removal of the first 10 cm spit a group of five rocks was apparent in the southeast corner of the unit which appeared to form a rough circle. Some of these rocks were apparent on the surface prior to excavation. This feature was labelled as 1:1 Feature 1. The feature comprised sandstone and limestone fragments, the sandstone chips more angu- lar than the limestone. Ten of each type of stone were noted totalling 3.9 kg of sandstone and 0.7 kg of limestone. Each piece of stone averaged 2cm x 2cm x 1cm. The matrix in 1:1 was noted to be deep red-colour- ed clay. A number of artefacts were recovered from the first spit including a hammerstone (cat. 709), two sandstone flakes (cat.s 710 and 712), a piece of rounded limestone (cat. 713) and a whetstone fragment (cat. 711) A further 10 cm was removed from the unit and in the NW corner natural bedrock was encountered. In this spit, 1:2, several artefacts were found including a possible chert flake with evidence of heat exposure (cat. 715), a whetstone fragment (cat. 716), a sandstone flake (cat. 717), a small whetstone or fragment thereof (cat. 718), a sandstone flake (cat. 719) and another fragment of sandstone whetstone (cat. 720). Within the feature labelled as 1:1 Feature 1 a quartz fragment was uncovered (cat. 714). This feature comprised a pile of small sandstone chips which were angular in shape and apparently comprising two layers of stones ranging from 50 cm to 5 cm in size.

The large boulders on the sides of the unit appeared to have some softer soil around and under them which may represent a pit into which they were placed but the excavator, Chang, could not state this conclusively. Unit 3 terminated at natural soil/bedrock at between 50 cm in some areas and 20 cm below sur- face in other areas of the trench.
