Bronze Age (2000-500 BCE )
From a study of Leaane Mountain, north of Dromahair.
“By the Bronze Age, cereal cultivation had ended and the environment had further deteriorated, so that the landscape was dominated by sedges (probably cotton grass) and grazing would have been very poor. It is quite possible that precipitation was higher at this time, since cotton grass is tolerant of very wet environments. It is likely, from the presence of the river terraces, that soil erosion occurred at this time, which would be consistent with a picture of heavy grazing pressure and soil degradation.”
A bronze Age dagger was ‘found in a bog at Keelogyboy’ and handed in to the MNI in 1948 . The blade is still sharp and in good condition.
