Explanation of Gravity Hill of Mainpat by using digital Elevation Modeling

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.
