Which mountain is called Killer mountain?

Excuse me, I'm curious about a particular mountain that's been labeled with a rather ominous name. Could you please enlighten me on which mountain is commonly referred to as "Killer Mountain"? I'm intrigued by the reasons behind this nickname and the history associated with it. Is it perhaps due to its treacherous terrain or some other perilous characteristic? I'd be grateful for any insights you could provide.
