Mount Diablo is a mountain on the Diablo range in the San Francisco Bay Area of Northern California. This mountain has been the reported site of many ghost hauntings, paranormal phenomena, and cryptozoology.

C: This is more like, local history than folklore, but Mount Diablo was like the big mountain range in the area. And everyone was like, “Oh! Why’s it called that?” Um–

L: Cause Diablo!

C: Cause Diablo! It was like . . . The Native Americans called it something because of like, the plant life on it–or something– and “Ah, demons” says the Spanish. This mountain has demons and thus said “Mount Devil”.

Thoughts:
It’s a chicken and the egg scenario of what came first — the paranormal sightings on the mountain, or the name of the mountain itself. Undoubtedly, one influenced the other into existence. It would be almost criminal to not have spooky stories about a place called Mount Diablo.
