Anyone who has walked on the North York Moors has come across flagged paths, or trods. Once commonplace, trods have been fast disappearing since 1900 when photographers such as Frank Sutcliffe and Tom Watson captured their ubiquity in villages, along dales and on the moors.
 
Trods of the North York Moors contributes to the preservation of the existing flagged paths by charting their exact locations and by explaining to readers - be they walkers, archaeologists, historians or geographers - the unique nature of their historical significance.
