"--- where did F.Dobie get his map of Tayopa? While 100% accurate, where
?"
Possibly from his friend Henry O. Flipper?
From mobeetie.com; (nothing about the map, just good early info about the man.)
"Flipper became the first black graduate from West Point on June 14, 1877, after enduring four years of loneliness and isolation among the predominantly white cadets who, from time to time, harassed and mistreated him. When Flipper was handed his diploma, he received a standing ovation from his classmates and the spectators for his four years of dedication and courage. Major General John Schofield, West Point's Superintendent, gave a tribute to Flipper's bravery against isolation and exclusion by his classmates. He stated, "No white cadet had ever been burdened with the hope of an entire race on his shoulders. Anyone knows how quietly and bravely this young man--the first of his despised race to graduate from West Point--has borne the difficulties of his position; how for four years he has had to stand apart from his classmates as one with them but not of them... ." Henry O. Flipper became the first black officer in the United States Military Service."

"Beginning in 1901 Flipper spent eleven years in northern Mexico as an engineer and legal assistant to mining companies. He joined the Balvanera Mining Company in 1901 and remained as keeper of the company's property when it folded in 1903. William C. Greene bought the company in 1905, renamed it the Gold-Silver Company, and placed Flipper in the legal department, where he handled land claims and sales and kept mining crews out of trouble with the local authorities. Greene, who had learned earlier of Flipper's research on the Lost Tayopa Mine,
sent him(Flipper) to Spain to do more investigation. The story of Flipper and the Lost Tayopa Mine appears in J. Frank Dobie's Apache Gold and Yaqui Silver."

"For the knowledge of our Vicar General, I have written this to inform our Superior. This inventory, written by a Jesuit and sealed on 17 February, 1646, was
found by Henry O. Flipper, the Spanish legal expert, surveyor and historian of mines and mining, in 19121. It tallies almost exactly with another of the same date which had been in the possession of the priest of Guadalupe de Santa Ana, a tiny village in Sonora, Mexico, and which came to light in 1927. Both are headed: A true and positive description of the mining camp Real of Our Lady of Guadalupe of Tayopa, made in January 1646, by the Right Reverend Father Guardian Fray, Francisco Villegas Garsina y Orosco, Royal Vicar-General of the Royal and Distinguished Jesuit Order of Saint Ignacio of Tayopa, and Jesuit of the Great Faculty of the Province of Sonora and Biscalla, whom my God keep long years."
