Origin of the Lue Treasure:

  The actual origin of the Lue treasure is currently unknown as it has yet to be factually found, therefore I find it better start with covering the story of the Lue treasure and the myth of the origin of this map.

Theory 1 (Nazi Gold):
There have been many rumors and even some found Nazi gold in Europe, but the Lue treasure is the only known myth of Nazi treasure theorized to have been buried in the United States. After WWI it was said that Hitler had sent an unnamed Nazi agent spy over to the United States with approximately 100 tons of Spanish gold, with which they were to flood the market with gold inflation in hopes of collapsing the gold based US treasury. It was said the American Gold Act was passed around this time, preventing the plot. The Nazi gold was buried on the property of an unnamed spy, and has yet to be found. After the death of the spy, Hitler supposedly sent over more Nazi agent spies in attempt to recover the buried gold, but after digging up the area surrounding the home of the unnamed spy, were unable to find the buried Nazi gold using the recovered map. The map was later recovered by the CIA and allegedly published by the FBI in the 60s or 70s in search of the treasure, giving this theory some weight. It has also been published in the 1971 treasure hunting book "Treasure of the Valley of Secrets" by a notable treasure hunter Karl von Muller, by Deek Gladson. The book is currently on sale with one used copy remaining on Amazon. The accompanying review by F. Hollister says:

What treasures here do Mammon's sons behold! - Quarles

Treasure of the Valley of Secrets is one of the most useful books for treasure hunters - and treasure finders - ever written. Sadly, copies are almost unobtainable today.

The cover promises "An incredible, documented story of a Cave of gold that may be worth billions. Intrigue, danger, wealth, history......since 1905. High adventure in the Sangre de Christos!" And the book delivers.

TofVofS is a detailed account of KvonM's search for and research into this amazing story. Was there an armed military camp located at the headwaters of the Purgatoire ("Picketwire") River in southern Colorado? Did a crazed genius manufacture three "airships" (dirigibles) as part of a plot to take over the United States? Was this potentially the most violent offshoot of the early 20th Century Western labor movement?

And is there a Cave of Gold located in the Valley of Secrets, covered by a landslide and marketed by trees that fell uphill?

This book won't answer those questions - although it does provide considerable food for thought.

Nobody has written more useful information for treasure finders than "Karl von Mueller" (Charles Dean and Gladyce M. Miller were the husband and wife writing team "Deek Gladson"). He wrote Sudden Wealth, the Treasure Hunter's Manuals, The Encyclopedia of Buried Treasure Hunting, the Master Hunter Manual, edited the National PROSPECTOR's Gazette and Treasure Hunter's News, the Exanimo Express newspaper, and much more. Those books are rather pricey today - as are first editions of THM #6 & #7. When you start finding and making money then you will want to purchase all of these - but one step at a time.

And with reference to "Sangre de Christos" who can argue that such a treasure hunt would not be an adventure? This appears to bring light to a second map I found on a treasure hunting forum via Google Image search, which appears to depict some form of a holy grail:
