A continuous chain of Mesolithic rockart adorns the walls of the North Karanpura rift valley, interspersed in the beautiful garment of the perfumed brilliant white Bridal Bouquet creeper which flowers throughout the winter months. As noted, these sites were brought to light over successive years, beginning with the Isco rock art in l99l. Today they are a well established gallery of prehistoric rock art of India, with the additional dimension of a palaeolithic base on one side, evidence of continuous civilization and a continuing mural painting tradition by the Adivasi villagers on the other side. The Sat-pahar consists of a series of seven triadic ranges in a complex forming its own basins and stream valleys, upon the tops of whose ranges, in the flanks of whose valleys, are found the fantastic rockart of a glacial period painted in red haematite and yellow lignite, for both of which the range is famed. Both the Thethangi (15x15, 15 x 10, 15 x 15 ), and Sariya ( 5' x 8')rockart face directly the abomination of the Piperwar, Ashoka-I and Ashoka-II opencast coal mines. The border of the mine blocks was initially promised to be kept a couple of kilometers to the south , but it has been brought right up to this beautiful range of hills, with an attendant railway for coal haulage being built along the base of the hills.

The rock art covers a large grey sandstone expanse over fifty feet long and thirty feet high which is painted with zoomorphs, anthropomorphs, geometrical designs in boxes, very realistically painted spotted deer ( Axis axis), mandalas, cattle, and ritually arranged frogs. Both the Thethangi and Sariya rock art caves are very threatened by the coal expansion project to the base of the hill. The new railway line presently under construction under the hill is causing huge dynamite blasts to crack the cave walls already, and the rock art is in danger of collapsing. The site has yielded a wide array of stone tools, flakes, microliths, borers, strippers and handaxes.
