Shillong Plateau is an outlier of the plateau of peninsular India and covers most of Meghalaya. The general altitude of the Plateau is about 1,500 m and is a rolling tableland.
The plateau's western, northern, and southern escarpments are called the Garo, Khasi, and Jaintia hills, respectively. The extraordinary straightness is one of the notable features of this plateau. It is made up largely of precambrian rocks acutely folded and steeply dipping, with an overturned fringe of mesozoic and tertiary sediments.
