The Satpura Range is a range of hills in central India. The range rises in eastern Gujarat running east through the border of Maharashtra and Madhya Pradesh and ends in Chhattisgarh. The range parallels the Vindhya Range to the north, and these two east-west ranges divide Indian Subcontinent into the Indo-Gangetic plain of northern India and the Deccan Plateau of the south. The Narmada River originates from north-eastern end of Satpura in Amarkantak, and runs in the depression between the Satpura and Vindhya ranges, draining the northern slope of the Satpura range, running west towards the Arabian Sea. The Tapti River originates in the eastern-central part of Satpura, crossing the range in the center and running west at the range's southern slopes before meeting the Arabian Sea at Surat, draining the central and southern slopes of the range. Multai, the place of Tapi river origin is located about 465 kilometer far, south-westerly to Amarkantak, separated across by the hill range. The Godavari River and its tributaries drain the Deccan plateau, which lies south of the range, and the Mahanadi River drains the easternmost portion of the range. The Godavari and Mahanadi rivers flow into the Bay of Bengal. At its eastern end, the Satpura range meets the hills of the Chotanagpur Plateau. The Satpura Range is a horst mountain and is flanked by Narmada Graben in the north and much smaller but parallel Tapi Graben in the south. Geography The eastern portion of the range receives more rainfall than the western portion, and the eastern range, together with the Eastern Ghats, constitute the eastern highlands moist deciduous forests ecoregion. The seasonally dry western portion of the range, together with the Narmada valley and the western Vindhya Range, are within the Narmada valley dry deciduous forests ecoregion. This mountain range servers as a natural border between Maharashtra and Madhya Pradesh state. The Narmada and the Tapti are major rivers that drain into the Arabian Sea. The Narmada originates in eastern Madhya Pradesh ( India) and flows west across the state, through a narrow valley between the Vindhya Range and spurs of the Satpura Range. It flows into the Gulf of Khambhat. The Tapi (also known as Tapti) follows a shorter, parallel course, between south of the Narmada, flowing through the states of Maharashtra and Gujarat to drain into the Gulf of Khambhat. Ecology Most of the Satpura range was heavily forested;
