Bukan-IX burial ground is located 7,5 km south-west of Aksai Village, 7,2 km north-east of Uzynbulak Village in Raimbek District of Almaty Oblast. Archaeological site of the Bronze and the Early Iron Ages was discovered by Alamaty reconnaissance expedition of A.Margulan Institute of Archaeology in 2005. Burial complex occupies the hillside in the foothills of northern slopes of Kuluktau Ridge, on the triangle platform between two steep ravines.
Necropolis of different epochs consists of 50 barrows of the Early Iron Age and about 20 rectangular and square shaped stone fences of the Bronze Age. The Bronze Age fences are accumulated in north-western and central parts of necropolis. The fences are made of large stone slabs installed vertically on the edge, and put in layers smoothed-down river boulders, rising above the surface to 0,2 m. Dimensions of the fences vary from 3 x 4 m to 6 x 8 m. Fences and graves are sedimented by alluvial layer so that they can hardly be seen on the surface; that is why a total number is uncountable. The Bronze Age complex covers an area of about 10 000 sq m. Specific features of burial constructions of the Bronze Age refer them to Kulsai culture spread in western extremity areas of Ile Alatau Mountains, northern slopes of Kungei Alatau, Kuluktau and Uzynkara Ridges. The monuments of such type are attributed to the Late Bronze Age (XII-IX cc. BC). As these complexes with a large number of burials are widely spread in vicinity of every gorge, it is presumed that this territory was the stationary residential area of a large tribal unit.
Barrows of the Early Iron Age are scattered all over the territory of the burial ground and stretched to lines in general direction from north-east to south-west. Embankments are built of earth and stone, fallen, smoothed, flattened, with a stone ring encircling the basis, covered with turf. The largest are plundered. Diameters vary from 3 to 10 m, 0,2 to 0,5 m high. External stone rings up to 15 in diameter are observed around majority of barrows. Constructional features of embankments attribute the burial ground to the Late Sakae period of the second half of the 1st millennium BC.
