GEOSITE

THE DEIRCS

Glacial corries and U-shaped valleys overlooking Lough Mask

Deirc, Irish for hollow, is used to describe the shallow lakes in the glacial corries of the Owenbrin Valley and around Maumtrasna. Corries are where glaciers are born: snow accumulates, turns to ice, flows downhill and erodes the mountain in a circular fashion. The view from The Deircs over Lough Mask highlights the contrast with the limestone lowlands.

Our Code of Conduct

Whilst exploring our geosites, remember to follow these simple principles to help keep our beautiful landscape spotless and to preserve it for generations (those living here and those visiting here) to come.

  • Ask landowner permission before walking on their land as most of the region, including the uplands are in private ownership.
  • Leave No Trace by following the 7 principles highlighted to the right
  • Do not hammer or remove rocks without permission
  • Follow our Fossil Code

More information on our code of conduct is available here.
