Today we continued in the northern quadrant locus 2. The capstone is at a depth of 97cm from the central point and 1.6m x 1.2m. Cleaning around it we revealed medium sized stones that seem to curve around the north of it, maybe 2 rows. Some of the stones, however seem haphazard and there is a gap between the capstone and the small stones in the center/apex. There is a row of 3 running along the NW unit wall, 1 large (another capstone?) that is under the small center stones at an angle and goes into the eastern quadrant, and medium ones further north that meet with the ones surrounding the capstone and extend to the eastern quadrant. The large capstone seems to be chalk and the stones around it are tuff, chalk, and basalt.
