Greetings Earth lovers and Poetry writers! I am posting the MACGeopark Poetry Map Prompt a bit later today because…you know…life laundry, messages (as they call those hunt and gather errands in Northern Ireland); a neighbour needed a lift to fetch their car that had been mended. They day evaporated and I am just getting down to this after a hastily eaten tea whipped up in the space that of a Bewitched nose twitch. (Beans on toast with a fried egg if you are truly curious.) Today I want to highlight a dramatic site in Marble Arch Caves UNESCO Global Geopark that you cannot fail to notice if you travel the Blacklion (Cavan) to Florencecourt (Fermanagh) Road. The border seamlessly moves from Cavan with a segue into a “Welcome to Fermanagh” sign – no Customs post or passport control. This road known locally as the Marble Arch Road and it leads to many of the Geopark’s best known sites. Hanging Rock dominates the landscape. I remember seeing it for the first time twenty years ago and feeling full of awe as we drove past. It has showstopper writ large. If it were a Broadway musical it would be the 10 o’clock number.
But as I passed by with the jaw hanging loose, little did I know its truly remarkable nature.
Overlooking Lower Lough Macnean is a magnificent 50 m high limestone cliff – the Hanging
Rock. The limestone from which the cliffs are formed was created around 340 million years
ago during the lower Carboniferous geological period, when Ireland lay close to the
equator. Located on the edge of a supercontinent, where sea-levels were higher, the area
that we now call Ireland was covered by a shallow tropical sea. The limestones formed by
the accumulation of lime-mud on the bottom of this ancient sea floor and from the remains of dead sea creatures that would have thrived in these waters. Limestone formation is a very slow process; layers and layers of limey deposits build up on the ocean floor and are
compacted by the weight of the water over millions of years. Closer inspection of the
limestone will reveal, fossils (typically bones or shells) of creatures that lived in this ancient
tropical sea. This specific type of limestone is known as Dartry limestone.
Interestingly, two stream risings lay at the base of the cliff, known as the Hanging Rock Risings. One of the risings is constantly active, while the other dries up during times of low rainfall. The risings are traced to only one source, Legacapple on the Marlbank above, but the water is believed to combine from a number of other sources.
Yew and juniper cling to its face. At the bottom of the cliff is one of the finest ash woodlands
in Northern Ireland. It is believed that the great variety of lichens found here indicate
woodland cover since ancient times. An area was clear felled in the early 1940s and has
now grown back naturally.
To the west, in Rossaa Wood, oak, beech, great willow and elm have grown to full maturity
and shelter a rich variety of plants. There are slopes covered in grasses amongst which
grows the colourful Welsh poppy. toothwort, a parasitic plant, lives on the roots of hazel and
elm. It looks unusual as it is totally white and stands out against the mosses on the damp
woodland floor. Red squirrels can occasionally be seen in the woodland while the elusive
pine marten has been sighted in recent years.
Local legend says that a rock dislodged from the cliff and fell onto a local salt trader takingMartina O’Neill, MACGeopark Development Officer, Partnership & Engagement
shelter from a storm. This rock became known as the Salter’s Stone or Cloghoge and sits
prominently at the road side to the east of the reserve.
A geoheritage poem based on Hanging Rock can tap into many of the elements of this MACGeopark site. First, there is the distinctive profile.
The other components are wind and water, the fossil record in the limestone and.in the many tree species. Yew and juniper are considered some of the ‘first trees’ to have emerged after the Ice Age Melt. Indeed, at Florence Court House and Grounds, a National Trust site further down the road, there is a yew that is referred to as ‘The Mother Yew’ of Ireland, as they have the oldest representative of the species Taxus baccata ‘Fastigiata’. This is ancient landscape on so many levels.
You still have time to submit a poem to put this site onto our digital Geopark Poetry Map. Your poem may be represented alongside the commissioned work of five poets from Northern Ireland and the Republic of Ireland. If you want to submit a poem in Irish that would be very welcome, but please include the English translation alongside it. If you would like full guidelines please email GeoparkPoetryMap@gmail.com. The closing date is 15th June 2021.
