Kamennaya Balka is a natural monument under the protection of the Rostov regional government. Kamennaya Balka comprises multiple campsites of ancient humans dated back to the Stone Age (late Paleolithic period). This is an open-air site near the village of Nedvigovka in Rostov oblast located on the promontory of the right bank of a deep old ravine which enters the Mertvij Donets river valley. The unity of several campsites found in Kamennaya Balka is attributed to Kamennobalkovsky culture.

There are three campsites – platforms for season settlements in Kamennaya Balka: Kamennaya Balka 1 (14,500 BCE, existed during a period characteristic of cold, wet weather and plenty of forests); Kamennaya Balka 2 (16,000 – 15,500 BCE, its foundation was due to a temporary climate improvement in the northern Azov Sea area). Monuments of Kamennaya Balka were discovered by M.D. Gvozdover in 1957. A systematic excavation began under the direction of Gvozdover and the Research Institute of Moscow Lomonosov State University from 1958 until 1971. The excavations were conducted intermittently from 1957 to 2005. There is one more campsite in Kamennaya Balka: Third Cape, also known as Kamennaya Balka 3. It was discovered by Marianna Gvozdover in 1962. From 1990 the investigation of Third Cape was continued by an archeological expedition under the direction of State Historical Museum and N.A. Khaykunova.
