A group of Altay archaeologists was doing obligatory field research before the construction of a road from Gorno-Altaysk to Urlu-Aspak when they suddenly found a fragment of an ancient settlement (here). The settlement was relatively large, but due to the time constraints only a small part of it that is to be buried under the road was explored. Multiple pieces of ceramic crocks in good condition and stone tools were found. But the most interesting things were strange channels dug in the earthen floor of the houses. Archaeologists still can't find a reliable explanation for them. One version is that the ditches were a part of the heating system: they channeled the warm air from the fireplace and warmed the floor.
No ideas on the dating of the settlement as far. The works will continue in the next season.
