Save the Date! Forrest’s new book, Once Upon a While, launches November 2nd.
Of note: Forrest intended to leave his car in the parking lot of the Denver Museum of Nature and Science.
Read the enlightening forward by Douglas Preston by clicking the link above. He references Codex, the book he wrote based on his knowledge of Fenn and his plan for hiding the treasure chest.
Forrest Fenn’s Treasure Chest
I read that book early in my search (along with several other of Preston’s suspense/horror novels, and then I read his tale of his retracing of Coronado’s journey north from the border of Mexico.
(Re-)Inspired? Why not shoot for the moon?

Where is a picture of cover of his new book??
Click on Dal’s Home Page after clicking the link: Save The Date and scroll to the second image for a peek.
Is this real? Has it been solved? How long will they lure people along?
I think it’s real. I don’t think it’s been found. I think he’ll let people know if and when it’s discovered/claimed.
As to your last question, each individual is different as to level of interest, seeking, and/or obsession. People are still searching for Captain Kidd’s treasure, no?
