Two sections of a broad turf bank have been recently (2017) discovered on the Earnal sliabh.
An intermittent linear feature, that can seen to be continuous on LiDAR imaging
Heather-covered turf
Ditches on both sides
Visible on LIDAR low resolution 10 m
Extends 1 km
1. NM02612 46321 55 m long; 6 m wide; 0.8 m high
2. NM01926 46405 150 m long; 7 m wide; 0.5 m high
The turf from this area was heavily extracted at the end of the 18th century as the island experienced fuel poverty. This may account for the fragmentary remains of this structure.
