Students of the IIMK team led by V. A. Semyonov and M. E. Kilunovskaya opened a burial at Eki-Otuk site. The work was conducted in unusual and even extreme conditions; an underground river flows right through the burial - one of branches of river Eerbek , which flows along all the digs on the surface.
During investigations of this burial, a Chinese buckle was found with an image of Teo-te mask. Presumably the find can be dated to 19th-6th centuries before our era. It needs to be noted that this is the first time in his lengthy working experience that V. A. Semyonov has seen a buckle of this type in Tuva.
