The Man with the Bone - S1-E18
Character mistake: The finger bone found in the dead man's hand was said to come from somewhere near Assateague Island, to which Hodgins replies, "That's where the money pit is." The "Money Pit" is actually located on Oak Island in Nova Scotia, not on Assateague Island, in Maryland/Virginia. He also says that they dug it out to about 150 feet, which is also incorrect. The 1971 Triton excavation was able to dig a shaft to a depth of 235 feet. What is said to be on Assateague island is the legendary lost Spanish galleon La Galga, not the Money Pit. (00:02:55)
Answer: Answering my own question here but, having contacted various people involved in the production of Bones including Kathy Reichs, Hart Hanson, Eric Milligan, and Deirdre Lovegood who portrayed Taffet onscreen I finally have the answer. No-one know how she did it due to her constantly working alone. And she never revealed this information before her death.
