What is recorded here

Drumnafinnila Barr is a broad east-west ridge in County Leitrim where a small mound once separated the county from Cavan. The 1907 Ordnance Survey map still shows it as a boundary marker, but the mound itself has nearly vanished from the land. It belongs to a handful of survey markers built across the ridge, most of them lost to time or forgetting. What remains is a line on paper and a name in a list, not a shape you can walk to.

Situated on a broad E-W ridge. It is marked only on the 1907 edition of the OS 6-inch map where it is described in italic lettering as a 'Mound' marking the boundary with County Cavan. This is one of about six cairns or mounds in this area erected by the Ordinance Survey, and very few of them are left. It is the same as (CV005-017----).
