These drumlins are formed of glacial till which was shoved up against the Slieve Croob hills some 13,000 years ago. The surface of the drumlins is free draining and has deep soil which supports good pasture land, but the low ground in between collects water and encourages the formation of inter-drumlin wetlands. Such a hollow can be seen in the middle ground left. The Slieve Croob range can be seen in the background.
