Chota Nagpur Plateau has the remains of an old fort belonging to the Nagavanshis. The Chhota Nagpur Plateau is a continental plateau—an extensive area of land thrust above the general land. The plateau has been formed by continental uplift from forces acting deep inside the earth. The Gondwana substrates attest to the plateau's ancient origin. It is part of the Deccan Plate, which broke free from the southern continent during the Cretaceous to embark on a 50-million-year journey that was violently interrupted by the northern Eurasian continent. The northeastern part of the Deccan Plateau, where this ecoregion sits, was the first area of
Tsalka Plateau precipitation rate is 740 millimetres. The Tsalka Reservoir occupies the centre of the plateau. Most likely covered largely by forests from Neolithic through Middle Bronze Age ca. 1500 BC, the land today represents mainly ancient dolomitic lava and is largely infertile. Before the Soviet Union, crop growing on the plateau was hindered by severe weather conditions, hail and field mice, which is why animal husbandry and beekeeping were more preferred forms of agriculture. The Tsalka plateau is home to the ancient Trialeti culture, with tumuli dating back to the second millennium BC, discovered in the 1930s. Some tumuli have stone-lined
