In the first information about the existence of the ruins of ancient cities on the southern shore of Lake Balkhash belong to the end of the XIX century. In the 1960s, under the leadership of
Kimal Akishev, K. M. Baypakov, and L. B. Yerzakovich, archaeological research was conducted on the settlement. The Karamergen settlement dates back to the IX-XIII century and is identified with the city of Gorguz. A medieval caravan route passed through the cities of the southern Balkhash region, in the lower reaches of Ili, along the Ortasu channel (or. Ili), where the remains of the cities of Karamergen,
Aktam, and Agashayak were found. The route then went to the shore of
Balkhash, and along the Uzun-Aral Peninsula, which almost connects the southern and Northern shores of the lake, leaving a
strait a little more than 8 km wide. ==Description==
