The Dartmoor Parishes of Gidleigh and Throwleigh share a boundary from Wildtor Well, through Gartaven Ford and Whitemoor Marsh then off the high moor and onto Forder Brook. The boundary then follows Forder Brook past Ash, Forder and Chapple before descending under Blackaton Bridge and Highbury Bridge en-route to the North Teign River just downstream from Gidleigh Park. There are many inscribed boundary markers / stones along this route especially on the high moor.
This post covers a short section of the boundary along Forder Brook on which there are three inscribed boundary markers / stones. Intriguingly, one of the three inscriptions appears to be located incorrectly on a stone just inside the neighbouring parish.
