Greetings from a scattered sunshine day here in a MACGeopark community. I say scattered sunshine because there is still the odd raindrop now and then. But at least it is not the hail stones that drummed on our roof yesterday! Spring is coming late to us in 2021, which may be why we just bought ourselves an upcycled fire pit. It is made from old tire rims and other bits and pieces. If we are going to have a cuppa with friends outdoors then we shall be swathed in blankets and can toast our toes along with the marshmellows this summer!
For today’s Geopark Poetry Map prompt I am sticking with the water theme. Because, along with rocks, water is a lot of what we have got! Today, I want to highlight Shannon Pot, the point when the underground source of the River Shannon bursts above ground to pour itself along ever widening banks down the length of the Republic of Ireland. My husband and I live in Dowra, the first village on the River Shannon after it’s rise a few miles north We pitched up in Dowra on a Mart Saturday back in September 2001. Little did I know then that this small corner of Geopark heaven would wind up being the place I have been resident longest in my lifetime. Who would have thunk it?!
But…back to the Shannon Pot:
The Shannon Pot is located in the foothills of Cuilcagh Mountain and is regarded as theMartina O’Neill, Marble Arch Caves UNESCO Global Geopark Development Officer, Partnership & Engagement
source of the River Shannon, the longest river in Ireland and the UK, with a length of
approximately 280km. The river flows from its source on Cuilcagh Mountain, to its estuary
below Limerick, and together with its tributaries drains an area of some 15,500km2, or about
one-fifth of the island of Ireland.
The Shannon Pot’s fame can be traced to the legendary Finn MacCool and the Fianna, the
great warriors of Irish mythology. Legend has it that Síonnan, the daughter of Lodan (a son
of Lír, the Celtic God of the Sea) came to the Shannon Pot in search of the great Salmon of
Wisdom. The salmon was angered by the sight of Síonnan and caused the pool to overflow
and drown the maiden. Thus the Shannon Pot was created. As surface water flows down from Cuilcagh Mountain, it will eventually sink and flow as underground streams and rivers. Up until recently it was thought that the Shannon Pot was the ultimate source of the River Shannon, but water tracing experiments have revealed that the Shannon Pot is fed by a variety of streams that sink on Cuilcagh Mountain, the furthest of these being over 10km away in county Fermanagh.
In this region, whenever water sinks underground, it works its way downwards through pure limestone (Dartry Limestone Formation) until it reaches the impermeable muddy limestone(Glencar Limestone Formation) below, forcing it to travel along this boundary until it intersects the surface as a spring or resurgence. However, the Shannon Pot is unusual as
the resurgence here is found within sandstone and shales, meaning that there is an
additional influence on the underground hydrology, apart from the lithology. In this instance
there are a number of faults that are most likely to have controlled the flow of groundwater,
acting as conduits instead of the limestone itself.
The hydrology of Cuilcagh Mountain has been studied for over 30 years, with many
important water tracing experiments being conducted to determine the underground flow of water.
Our very first Christmas in Dowra we visited Shannon Pot before having our dinner. We had closed on the sale of our new home not three days prior. It felt very peaceful and we were completely in a state of awe and gratitude that we could afford to live in such a gloriously beautiful place, so close to nature.
I also have very fond memories of visiting Shannon Pot with a USA visitor on a misty and rainy April day. The hawthorn was blooming in the hedgerows that line the path down to the Pot. Through the mist we saw this very white horse (often called greys) with a sheep. It felt very ‘into the magical.’
You can visit the Shannon Pot if you are in Ireland. It is along the posted Cavan Way hiking trail. If you visit by car there is a picnic spot and small playground to exercise the little ones.
Here is a video that my friend Jane Gilgun posted on You Tube ten years ago. The information is all still relevant and it gives a good feel for the landscape.
I hope these blogs will prompt geoheritage-themed poems that will put this site on our digital Geopark Poetry Map and inspire you to visit the Geopark. All the sites are open to the public now. You can get full submissions guidelines by emailing GeoparkPoetryMap@gmail.com. The closing date for submissions is 15th June 2021.
