The deep history of Ireland is written in its landscape. In Donegal, the waves crash against the coast, turning cliff to cave, cave to arch, arch to stack, over aeons of time, crashing endlessly; cliff, cave, arch, stack, each a moment in its transformation into what it will become. Imagine speeding this erosive action up, so that these millions of years, tens of millions of years, hundreds of millions of years, can be seen to pass in a time frame that is comprehensible to creatures as short-lived as us.
Or maybe those aeons of time – the mere blip in the history of the universe that it took to transform cliff to cave to arch to stack – is too vast to comprehend. How about a shorter time frame? From Donegal, we drive inland, through the u-shaped valleys, the hanging valleys, the cirques, the scree, the ribbon lakes of the most recent ice age. Shorter time, easier to grasp. 20,000 years. 50,000 years. Time when our ancestors, not yet here, lived and loved and laughed and adapted to (or failed to adapt to) the changing climate. The landscape here is barren, in hues of grey and purple, still in its post-glacial youth.
Down through Monaghan, the road winds through what the glaciers left behind as they retreated in a warming world. Now, we are getting closer to our time. Only 10,000 or 9,000 years ago. The blink of an eye. The drumlins, those hills of glacial debris, all sloping together, like eggs in a basket, their blunt stross ends facing back northwest in the direction of the retreating ice, their more gently sloping lee ends looking southeast to a warmer world. The drumlins are bright green farmland now, criss-crossed with hedges, stone walls and fences. Cattle and sheep graze on the mineral rich grass. We have made them our home.
From the drumlins we drive across the eskers, the long collection of the Eiscir Riada, dried streams of glacial melt water that left behind the stone and sand and gravel that we drive along and extract and graze our animals on.
And now I am home. In the Bog of Allen. The raised bog, so similar and yet so different to the blanket bog I walked across in Donegal. This too is a remnant of the last ice age, the trapped melt water with no escape from the depression at the centre of the island. As the world warmed, trees grew and died and grew and died, over 10,000 years. Heaney wrote of the bog
Missing its last definition
By millions of years.
They’ll never dig coal here,
Only the waterlogged trunks
Of great firs, soft as pulp.
Our ancestors lived here, buried their dead here, punted their boats here. Archaeologists have found hoards of gold buried here and urns of butter still edible after 5000 years.
In the blink of an eye, we have ripped up the Bog of Allen. Heaney was wrong when he wrote ‘The wet centre is bottomless.’ In my lifetime, we have reached the bottom – digging, extracting, exhausting. And what did we find there? An earlier history told in seashells and calcified rock. From a time before. But to comprehend that, we must step back from this moment, to look across millions, tens of millions, hundreds of millions of years.
