On the Bay of Bengal drift, toward the south of the Bheemunipatnam edge, is a region involving profoundly gullied red sand hills of around 4 km length and 2 km width You can find it in Google Earth. This territory is alluded in Telugu as "Erra Matti Dibbalu" which means 'Red Sand Hills'. It is limited by streams "Chittigadda" in the North-West and "Peddagadda" in the South-West. Amid that time the ocean level rose to as much as 150 feet and fell away ious circumstances to the ebb and flow level. Between these swaying ocean levels the drift was submerged and uncovered again and again, gigantic volumes of mud, sediment and sand secured the drift from where the ocean water had retreated. Because of the extraordinary changes in climatic conditions the material under the sandy hills "heated" in the sun like a block gets prepared in a furnace prompting the exceptional red sand ridges. Accordingly activity of the breeze and streaming water caused the profoundly gullied trademark scene.
