ABSTRACT:
Gravity hills are present all over the world. They are known as an antigravity hill, where laws of gravity fail, whereas it is just an optical illusion. This article is a systematic study of one of such places located at Mainpat of district Surguja Ambikapur Chhattisgarh. It is a recently discovered place and is one of the most visited tourist spots. Due to a lack of scientific approach, people assume it as a magnetic effect that attracts cars uphill. There is a stream of water moving uphill due to which it is also known as Ultapani, which means water with the reverse flow. By creating a Digital Elevation Model of Ultapani 3D map, elevation profile, a contour map is prepared, which gives the actual slope of the site. It is clear from data analysis and physical verification; there is no mysterious force or magnetic force that attracts water upstream. This is first attempt to explain that water is moving downhill due to gravity.
