James A. O'Kon is a author, lecturer, award-winning structural engineer, and Archaeo-engineer who has explored and researched Maya technology for forty years. He has combined his talents as a forensic engineer with archaeological field survey evidence to uncover the veil over the lost technology of the Maya.

In 1995 he surprised the archaeological community with his discovery of a lost landmark of Maya engineering, the long-span Maya suspension bridge at the Maya city of Yaxchilan, considered to be the longest bridge in the ancient world.
