The Killer Mountains are Arizona's Superstitions, the site of continuing casualties and catastrophes primarily connected with The Lost Dutchman Mine, discovered by a German immigrant Jacob Waltz (1810-1891) who was really a flying Dutchman since many of the legends attending him and his mine have not been pinned down. All through the years thereafter Coronado's children followed the ignes fatui--most recently Glenn Magill, a private investigator, alerted to the mine by a lawyer who later died. Primarily guided by an earlier book (Sims Ely's The Lost Dutchman Mine--1953) and finally securing maps via the son of a man who most nearly discovered it after Waltz and died there, Magill identified the mine: The post-discovery phase included further threats and attempted violence, and it ends dismally, down an empty shaft. . . But it's quite a story of great speculations, great expectations.
