German climber Nicholas Mailander and Elizabeth visited Pune for Yoga studies.
During his stay, an attempt to climb the Dukes Nose lead to the observation that the bolts were not proper and made from material available at that time. They had significantly low strength and short life with no guarantee of perfect placement.
The bolts were prone to accident and could give in at any time.
To find appropriate bolts, Nicholas carried a rock structure sample to Germany and tested for its characteristics.
As a result, he suggested a new bolt named ‘Mahatma Gandhi Bolt’(MGB)
