Ancient refuse, modern data
In the Kyzyl Kum desert of Karakalpakstan, along the ancient Akcha Darya delta, lie enormous heaps of discarded shells. These are natural formations, not kitchen middens—prehistoric garbage dumps—left by the Kelteminar culture, a Neolithic society of fishers and foragers who lived here between 5500 and 3500 BCE. First identified in 1939 by archaeologist S. P. Tolstov, the culture is named after a nearby abandoned canal. The people were semi-sedentary, living without agriculture or domesticated animals, relying instead on the resources of the rivers and the lake that is now the Aral Sea.
The middens record daily life. Composed primarily of countless mollusc shells, they also contain fish bones, remains of hunted animals like wild boar, and cultural artifacts. Kelteminar artisans produced pottery with pointed bases, often decorated with incised lines, and crafted tools like flint and quartz arrowheads. They lived in large, oval-shaped communal houses, sometimes measuring 24 by 17 meters, which may have sheltered an entire community of 100-120 people. These structures, along with the sheer volume of the shell deposits, show a long-term occupation of the Amu Darya river delta.
