A Russian archaeologist says he has discovered remains of a Bronze Age civilization in Russia's North Caucasus.  The North Caucasus is one of the world's most ethnically diverse regions, located between the Caspian and Black seas.  The discovery was in the mountains between the Kuban River and the site where the city of Kislovodsk stands today. 

Andrey Belinskiy says the settlements had carefully designed houses and oval courtyards and the mountain people later merged with the so-called Kuban culture, known for exquisite bronze artifacts.
