Had gone at Johna falls on the first day on 2011. It is situated at an edge of the Ranchi plateau, the Jonha Falls is an example of a hanging valley falls. The Gunga River hangs over its master stream, Raru River and forms the falls. One has to descend 500 steps to admire the surroundings. Water in the falls drops from a height of 43 metres.
The Johna Falls is an example of a nick point caused by rejuvenation. Knick point, also called a nick point or simply nick, represents breaks in slopes in the longitudinal profile of a river caused by rejuvenation. The break in channel gradient allows water to fall vertically giving risie to a waterfall
