History: Lost Mesa is a legendary mountain somewhere in New Mexico said in local lore to be the graveyard of the gods or an entrance to Heaven. Little is known about it, even its location; although several scientists, anthropologists, and various New Age gurus have made guesses as to its whereabouts, none have ever been corroborated by evidence.
One thing that is known is that the search for Lost Mesa has taken several lives over the centuries, from obsessed Spanish conquistadores to Gold Rush prospectors to modern-day adventurers. State and local authorities therefore politely discourage any inquiries.
