What is the "most dangerous" mountain in the world?

Everest? - nope.

K2? - nope

Annapurna? nope

It is Mt Blanc.

- talking about gross yearly total deaths , not percentage chance of dying on an individual mountain. (ie., statistics depends on what your definition of is is).

Why Mt Blanc? Because it is a playground for thousands of hikers, climbers, skiers, boarders, etc. Near population centers and money and easy to go there in sheer huge numbers.
