Fishing & Cruising Charts for Lough Corrib

& lakes in the West of Ireland

Cornamona Structure
We were surprised to film this. It may be geology, but it seems a long shot. This has every indication of being a man made structure of some type ( a pallisade ?) that has collapsed around a submerged hillock.
Cornamona structure 6

Zebra mussels prefer wood as a substrate, and can be seen here clinging rather selectively to "something" 14ft down.
Cornamona structure 4

This apparent structure is found on a remote and isolated area of shallower water, in what is otherwise quite deep water.

More surprises from Corrib.
Cornamona structure 3
The whole structure is roughly 35ft long, and needs a proper archaeological survey doing. This may well be the evidence that I have been looking for that the lake was inhabited during the period when the lake was substantially lower. It could conceivably also be the remains of a lake structure on poles.  
Cornamona structure
From this angle it appears to be a either a structure with roof frames, or a large  inverted and crudely constructed vessel.
