At least 12 discrete coal working sites are visible on historical and recent air photos and on lidar imagery in the fields between Seaton Burn and Brier Dene Farm. A network of linear features pieced together from the earlier air photos is likely to be the remains of wagonways that served the coal workings.
In his article of 1915 Tomlinson documented and plotted the ‘Old coal-pits and waggonways in the Hartley District’. Many of the features identified on the air photos and lidar imagery correlate with pits or wagonways depicted on this plan.
The linear feature running from a field south of Hartley (NZ3388 7542) southward to Brier Dene Farm (NZ3362 7398) appears to be the main route from which other short wagonways branched out to individual pits. Most of the wagonway remains appear as cropmarks but an earthwork section survives to the east of Briar Dene Farm.
Tomlinson’s investigation of the records shows that these pits were exploited between in the last 3 or 4 decades of the 18th century and the 1st decade of the 19th century, but that most pits were worked for less than 10 years and many for less than 4 years.
