Most people are familiar with the Freemasons, but there is another fraternal order that holds similar esoteric knowledge and was also prominent in the United States at one time, The Independent Order of Odd Fellows. At the higher levels, they have knowledge of maps, and specifically degrees, angles and grid lines. Odd Fellow's founder Thomas Wildey had his portrait, it would appear, emebedded with a secret about the North Pole region near Alaska.
