Greetings Earth lovers and Poetry writers this watery Sunday. We are on a land of lakes theme this weekend (and I do not mean to plug a certain USA brand of butter from Wisconsin. Wisconsin may have more lakes, but it is also twice the size of the island of Ireland.) Both Fermanagh and Cavan, however, claim to have one lake for everyday of the year. Which is why Marble Arch Caves UNESCO Global Geopark can claim to be the Lake District of Ireland. With so many to choose from surely you can put today’s lough on #MACGeopark digital Poetry Map.
Today’s lough is one that is close to my own home. Lough MacNean straddles the international boundary between Northern Ireland’s County Fermanagh and County Cavan in the Republic. There is an Upper Lough MacNean and a Lower Lough MacNean. Lower Lough MacNean is completely within the Fermanagh boundary. There is a little strip of river and wetland between the two with a bridge that links the villages of Belcoo in Fermanagh and Blacklion in Cavan.
The freshwater would have provided abundant fish and the system of loughs and rivers would have been a good way to navigate to better hunting grounds. Cushrush Island in Lower Lough MacNean shows evidence of habitation from the Mesolithic Age, when people first migrated to the island of Ireland. The many small islands would have made convenient stop offs. There are also remnants of crannogs in Lough MacNean, those man made islands (!) that modern eyes see as easily defended from marauders. But that is pure speculation. Some early ancestor decided to experiment with engineering. But, given the many megaliths surrounding the Lough MacNean area, it seems that the early dwellers were keen engineers, which is not pure speculation. We can still see the evidence of their labour and ingenuity.
This is the geological background to how this landscape was formed.
The single biggest impact on the landscape of the Geopark comes from the last glaciation.Martina O’Neill, MACGeopark Development Officer, Partnerships & Engagement
As huge ice sheets slowly crept across the entire area, acting like giant sheets of sandpaper
and removing everything from their path. Some of the ice moved westwards forming the
glacial valley of Lower Lough Erne and Lough Macnean. Indeed many of the islands located
within Lough Macnean are in fact drumlins. These form from till or boulder clay that was
sculpted into this shape as massive ice sheets slowly crept across the landscape during the
last glaciation. Glacial moraines are another relict of our icy past and this is a general name
given to material left behind as the ice retreated at the end of the last glaciation. They tend to be primarily composed of sands and gravels and the land bridge that connects Upper and
Lower Lough Macnean is an excellent example of a glacial moraine.
Moraines and drumlins walk hand in hand across the landscape. The island of Ireland has the largest moraine field on the planet and the Irish language gave geologists the word drumlin. It comes from the Irish droimnín, translating as little ridge. These whale-backed hills (metaphorically) swim in pods across the breadth of this island from County Down to Donegal.. You can find moraines and drumlins in many counties in Ireland. The moraines may not be seen, but the drumlins certainly can be seen and are the visual clue to what has gone on over the eons under your feet.
I hope thaat you have been finding some inspiration to submit poems to the Geopark Poetry Map. All sites are open to the public. But if you have to be an online visitor because of these pandemic times, you are also welcome to visit with your imagination and submit a poem, too. You can get full guidelines by emailing GeoparkPoetryMap@gmail.com. The closing date is 15th June 2021.
