The site has a 15 hectare mound (peaking at 18 meters above the plain and first settled in the early 4th millennium BC) and a 5 meter high lower town on three sides which was occupied beginning in the middle 3rd millennium BC and brought the site up to its maximum of 98 hectares. There are three named sub-mounds in the site, Tell al-Sara, Tell al-Duwaym, and Tell al-Tamr, with Tell Mas’ada lying just outside the site boundary. The southern extension of the mound is also known as Khirbet al-Fakhar. Archaeology dates this area to the middle 5th millennium BC though radiocarbon dates point to the late 5th millennium BC. About 40 hectares of the site are covered by the modern village of al-Hurriya including paved roads and mudbrick homes. The site was first examined and described by Van Liere and Lauffray in the 1950s noting a two stepped plateau with a ditch 100 meters from the foot of the mound. A scaled plan, based on aerial photographs, was published in 1963 which estimated the mound area at 116 hectares and the area within the circular depression as 216 hectares. Due to this large size Van Liere proposed it as the location of
Washshukanni. Excavation by a joint Syrian-American expedition (by the
Oriental Institute of the
University of Chicago and the Syrian Directorate General of Antiquities) was conducted beginning in 1999 and ending in 2010. Initial work in 1999 included an intensive surface survey based on 10 meter by 10 meter squares. The excavation was initially led by McGuire Gibson and later by Clemens D. Reichel. The site was abandoned at the end of the 3rd millennium BC. During the 2001 excavations a 400 square meter trench opened in the residential area of the lower town found that it was prosperous and had been sacked and abandoned at that time. Thousands of clay sealings have been found on the site, indicating the existence of a complex bureaucratic system. These sealings were once used to protect doors or containers from tampering and were impressed with stamp seals. Artifacts from Hamoukar can be seen at the Oriental Institute. Eye Idols made of alabaster or bone have been found in Tell Hamoukar. Similar Eye Idols from the same period have also been found in
Tell Brak, the biggest settlement from Syria's Late Chalcolithic period. ==Obsidian==
