The site located off the Sai Kung West Country Park north east of Hong Kong Island consists of many stone flakes and at least two large stone boulder (cores) from which the flakes came from, and spread over an area of about 200m along a pebble beach. The two large stone cores, of which the largest and well-used one measures 0.6m height, 0.6m diameter (at broadest), and 0.35m diameter at the top. They were seen on a falling tide and about 10m below the high tide mark, and approximately 1m below the predicted high tide for the nearby coast.


In 2007, HKUHG visited the area and viewed the large stone core when snorkeling in about 1m of water. In this latest 2016 visit, only the core and flakes above water could be seen, although there could be artefacts further out to sea, but an inspection was hampered by poor visibility and the soft silty seabed.


The site was investigated and documented by the Hong Kong Archaeological Society in 2004. From their research, they believe the site is more than 6,000 years old, given this was when the current sea level was achieved. The site appears to sit on a terrace adjacent to an ancient river running out of Tolo Harbour. They interpreted the site as an ‘ancient lithic manufacturing workshop’.


Many photographs were taken of the main core and some of the flakes. Only a few flakes seem to have secondary working, of which some were photographed.


A 3D model was made of the one main core.
