LARGE BARROWS IN THE TERRITORY OF THE MAMONTOVSKY DISTRICT OF THE ALTAI TERRITORY
The Mamontovsky district of Altai Krai is located in the central part of the south of the Ob-Irtysh interfluve. It is located on the border of the Kulundinskaya plain and the Priobsky plateau. Here passes the border between the steppe and forest-steppe zones. In this area in a small area there are several groups of burial mounds including very large mounds. These are such necropolises as Yermachikha-I, Chernaya Kurya-XI, Per-vomaiskoye I and Kurgan II. The largest mounds of these cemeteries reach a diameter of 90-100 m. The largest gravestone construction is the mound at the Pervomaiskoe-I. burial ground. It was surrounded by a moat and rampart about 180 m in diameter. These objects have been known since the 19<sup>th</sup> century. They were described by S.I. Gulyaev and VM. Florinsky. In the Upper Ob region east of the location of these burial grounds, large burial mounds have not beenm identified. The same structures were excavated at the Bugry burial ground in the Rubtsovsky district. The mounds with ramparts and moats from the Mamontovsky district belong to the end of the Scythian-Saka time.
