A splendid view, looking north, of Upper Lough Erne on the Cavan-Fermanagh border which dramatically Drumlin and Lake Terrain, Lough Erne
illustrates the characteristic drumlin and lake terrain in this part of the country. Crom Castle can be seen
directly north of the small tower in the middle of the river. The border runs across the photograph about halfway up.

Laminated Limestone
A sample of laminated limestone from the Meenymore Formation seen in Derrylin Quarry. The
laminations  are probably of algal origin, while the folding results from evaporite dissolution prior to
lithification of the sediment.
