“Enclosure No. 6, Cadboro Bay, near Victoria, B.C. (1897), formed of six large bowlders and some small stones … This structure is a nearly square enclosure … resting upon an outcrop near the crest of the hill rising westward from Cadboro Bay. The straightest sides of the six large bowlders are turned inward, and so the walls of the cyst are fairly straight. The enclosure was clean, save for less than two inches of moss growing on the bed-rock, while rubble and bowlders were banked up on the outside of the cyst.”
