Following the Cascades (Sweet Ilen – Part 7)

There’s a walk that goes down from Castledonovan to Drimoleague: it follows an ancient mass path and much of it is right alongside the Ilen River. At its northern end there is a section known as the Deelish Cascades: this is geologically fascinating, and gives us some insights into how our West Cork landscape was formed thousands of years ago.

. . . The oldest rocks exposed in West Cork are of Devonian age (410 – 355 million years ago) . . . These mostly red and green sandstones, siltstones and mudstones were deposited on a continental landmass in a low latitude desert or semi-arid environment. The sediments were deposited from rivers, whose flow was dominated by flash-floods fed by episodic rainfall, which originated predominantly from mountainous areas lying to the north which were were formed during the Caledonian Orogeny (mountain building event) in latest Silurian and early Devonian times. The environment was perhaps similar to the present day Arabian desert. This “Old Red Sandstone” continent extended over what is now northwest Europe. In Cork and Kerry these sediments accumulated in a large subsiding trough (the Munster Basin), resulting in one of the thickest sequences of Old Red Sandstone encountered anywhere in the world (at least 6km thick) . . .

Geology of West Cork, M Pracht and A G Sleeman, geological Survey of Ireland 2002

I have marked on this Geology Map the course of the Ilen River from its source on Mullagmesha Mountain to the tidal estuary which begins at Skibbereen. The map shows the ‘grain’ of the various faults which run SW to NE over the terrain: the river generally flows perpendicular to these faults, and the ‘grain’ is clearly seen in the exposed river bed running over the Deelish Cascades.

Praeger usefully simplifies the geological definition of the landscapes (for more on Praeger see Finola’s complementary post today):

. . . The story which geology tells as to how West Cork and Kerry got its present form is interesting, and I shall try to tell it in non-geological language. Towards the close of Carboniferous times – that is, after the familiar grey limestone which covers so much of Ireland and the beds of sandstone and shale which succeeded it were laid down on an ancient sea-bottom, but long before the beginning of the Mesozoic period, when the New Red Sandstone and white Chalk were formed – the crust of the Earth in Ireland and beyond it was subjected to intense lateral squeezing from a north-south direction. This forced it into a series of great east-west folds, thousands of feet high from base to summit – the Carboniferous beds on top, and below them and following their ridges and hollows the massive strata of Devonian time, and other deeper-buried systems. A series of pieces of corrugated iron laid one over the other will illustrate what happened. The folding was developed particularly conspicuously in the Cork-Kerry area. What we see is the result of this ancient crumpling, now greatly modified by the effect of millions of years’ exposure to sun and frost, rain and rivers . . . The more resistant slates, carved into a wilderness of mountains, still tower up, forming long rugged leathery ridges. A sinking of the land has enhanced the effect by allowing the sea to flow far up the troughs. That the ridges were longer is shown by the high craggy islands that lie off the extremities, and continue their direction out into the Atlantic . . .

The Way That I Went, Robert Lloyd Praeger, Methuen & Co London, 1937

While the upheavals of far-off eras reaching back millions of decades certainly laid the foundations of our landscape, the geological events which actually honed the shaping of the terrain as we see it today are far more recent – the ‘Ice Ages’ which developed only 30,000 years ago and had receded by about 10,000 BC. During that time sea levels fell and then rose again, and the topography and shoreline of the island with which we are familiar today was established. The ice sheets covered most of the land and were up to 1,000 metres thick. As they melted, glaciers fell away from the highest points and carved fissures into the slopes, creating valleys and rivers. One of the most extensive ‘local’ ice-caps was in south-west Munster where a ‘Cork-Kerry’ glaciation, centred on or close to the Kenmare river, developed independent of the general ice sheet. Our own ‘Sweet Ilen’ was a consequence of the ice movement, and the rock formations that we see in the Deelish Cascades are good evidence of these modern geological events.

All the way down the Cascades you will see evidence of the scouring of the rocky river bed, and huge ‘erratic’ boulders that have been carried from the mountain-top on the ice flow, to be deposited randomly – and picturesquely – in the torrent. Of course, you don’t have to know about geology to appreciate the walk: you are free to explore the well kept path and delight in this West Cork experience which has been laid out for us all through the mighty efforts of the Drimoleague Heritage Walkways and the Sheep’s Head Way.

Winter Light in West Cork: Lockdown Edition

We’ve both been dipping in to Robert LLoyd Praeger recently – Robert for this week’s post on the Ilen Cascades and me for pleasure. Praeger’s classic book The Way That I Went, was published first in 1937 and has never been out of print (this is the edition we have). My browsing reminded me that I tried a Praeger approach to explaining our West Cork landscape a few years ago, in a post post titled Wild Atlantic Light – the West Cork Winter Edition. I am having another go at it now with edited text and new photographs, all taken in the winter months. Mostly what I was trying to do then and now is to explain the West Cork landscape – what gives it its form and shape and colour and startling beauty. Being in lockdown since Christmas has forced us (even more than usual) to engage with our territory on a deeper level, seeking to understand what makes it the way it is.

Of this area, Praeger says,

At the Southern end of this land of great mountain promontories, in West Cork, you find yourself in a little-known and tourist-free region of much charm. You stay on Sherkin Island . . . or Cape Clear island . . . , at Schull or far out at Crookhaven: and you walk and boat and fish and lounge and bathe, and enjoy the glorious air and sea; towns and trams and telephones seem like bad dreams, or like fugitive glimpses of an earlier and inferior existence. A meandering railway penetrates to Schull, and the roads are as good as you could expect them to be in so lonely a country. All is furzy heath and rocky knolls, little fields and white cottages and illimitable sea, foam-rimmed where it meets the land, its horizon broken only by the fantastic fragment of rock crowned by a tall lighthouse which is the famous Fastnet.

Things have changed quite a bit since the 1930s, of course – how we wish that little railway was still running or that the ‘our’ part of Ireland had remained ‘little-known.’ But while it may seem that Praeger is describing a whole other world, enjoyed in the summer, the fundamentals remain. For example, as Praeger pointed out, West Cork is a maritime area and that affects our weather. It means that clouds are plentiful at all times of the year and that the weather can be highly variable and unpredictable. But the ocean, and the Gulf Stream it carries all the way from the Gulf of Mexico, ensure that we have a slightly milder climate than the rest of Ireland. Beside the sea, the air is full of negative ions. That’s a good thing. Negative ions stimulate our senses and lead to a heightened sense of wellbeing.

Sure, we can have rainy days and bitter winds in the winter, but there are lots of sunny days too. When the sun shines in the winter, it is filtered through those drifting clouds to produce those marvellous effects of light and shade that lend such drama to the landscape.

In winter too, the colours are highly contrasting – the green of the fields change abruptly to the blondes and golds of the higher mountains. The bracken turns the colour of amber and the fionán grasses provide an expansive sea of rippling heath on higher ground.

We don’t get snow very often, but it’s certainly visible on the high points, such as on the Caha Pass between Glengarriff and Kenmare. Praeger loved this dramatic geology with its crags and folds.

Under a blue sky the sea in West Cork turns the colour of the Mediterranean or the Caribbean. and this is particularly striking in the winter, perhaps because it’s so unexpected. They tell me it has to do with having a sandy bottom and I am sure there are other scientific explanations, but really, you have to see it yourself to believe it.

Our underlying geology (see Robert’s post again for Praeger’s explanation) provides the ruggedness, the exposed sandstone ridges, and the deep coastal indentations that characterise the landscape.

The end result of it all – the sunshine, the clouds, the mountains, the sea, the contours and colours of the land – is the kind of light that artists dream of. The sheer clarity of it is startling – you can see from one end of the peninsula to the other in a way that city dwellers have forgotten it’s possible to do. That clarity brings out every hue and allows all the colours to sparkle against each other.

The photographs in this post were all taken from the depths of winter to the first glimmerings of spring. Robert Lloyd Praeger found this area entrancing in the summer – he should have come in the winter! The last light of a winter evening would have set his heart aflutter.

Robert’s Favourite Posts

We had an unexpected – and unsolicited – accolade in the Irish Examiner last weekend! Tommy Barker wrote, in an article about Rossbrin (pictured above): “…The wonderful literary and visually rich website, http://www.roaringwaterjournal.com, by Rossbrin residents Robert Harris and Finola Finlay is a treasure, a sort of 21st century Robert Lloyd Praeger, online…” Of course, we went straight to our bookshelves to dip into our copy of Praeger’s The Way That I Went – An Irishman In Ireland, first published in 1937. Here’s an extract:

…At the southern end of this land of great mountain promontories, in West Cork, you find yourself in a little-known and tourist-free region of much charm. You stay on Sherkin Island (Inis Oircín, little pig’s island) or Cape Clear Island, at Schull (Scoil, a school) or far out at Crookhaven: and you walk and boat and fish and lounge and bathe, and enjoy the glorious air and sea; towns and trams and telephones seem like bad dreams, or like fugitive glimpses of an earlier and inferior existence. A meandering railway penetrates to Schull, and roads are as good as you could expect them to be in so lonely a country. All is furzy heath and rocky knolls, little fields and white cottages and illimitable sea, foam-rimmed where it meets the land, its horizon broken only by the fantastic fragment of rock crowned by a tall lighthouse which is the famous Fastnet…

Yes – that’s our West Cork alright (above is a view of the Mizen taken from Mount Gabriel). We hope that, over five years of writing this journal, we have indeed given a good account of this wonderful place which we are privileged to call ‘home’. Certainly, there is nowhere we would rather be. But Roaringwater Journal has not just been about West Cork: we have covered a fair bit of Irish culture and history as well. Last week’s post set out the six most popular articles that we have written in terms of readership numbers; today we are both reviewing our own personal favourites (see Finola’s here) and there is lots to choose from: 466 posts to date! All of them are listed by category in the Navigation pages.

Foremost in my own mind in terms of personal satisfaction is the series I wrote last year: Green & Silver. There have been nine posts in all, starting with my review of a book which I first read in 1963, when I won it as an essay-writing prize at school. The book, Green & Silver, told the story of a journey around the Irish canal system in 1946 (the year I was born), undertaken by an English engineer and writer, L T C ‘Tom’ Rolt and his wife, Angela. When I wrote the review 70 years had passed since the Rolts made that journey. Finola and I conceived the idea of retracing the steps of the Rolts, although not by boat: we drove and walked. It was to be an exercise in tracking the passing of time. We would find the location of every photograph that Angela Rolt had taken in 1946, and take a new one, so that we could compare the changes that had occurred over seven decades. There were many: the canals themselves, which were then near-derelict in places have now been well restored, and the island of Ireland has today an amazing but probably under-appreciated asset: a cross-border system of navigable waterways which connects Waterford, Limerick, Dublin, Belfast and Coleraine.

I have always had an obsession with wildlife, and one of my favourite posts summarises what wonderful natural things we have all around us here: The Wild  Side. We have written about the birds – choughs, eagles, sparrowhawks – and the little ones that come to our feeder and keep us entertained.

We will never forget our good friend Ferdia, who arrived on our doorstep on the day we moved into Nead an Iolair, and was a regular visitor (usually daily) over several years. Sadly, foxes don’t live for long in the wild, and he has now passed away. He was a very fine dog-fox and was undoubtedly the head of a large family. We hoped that one of his offspring might have taken his place on our terrace, but I suppose he just could never be replaced.

Of course, the pasture and coastline that surrounds us has fine creatures of the domesticated variety, too! (left and right below).

I have family roots in Cornwall and, during my time living here, I have become aware of many links between that westernmost peninsula of Britain and West Cork. In fact, those links go back into prehistory: in the Bronze Age – three and a half thousand years ago – copper was mined on the slopes of Mount Gabriel – a stone’s throw from where we live – and was mixed with tin from Cornwall to make the all-important ‘supermetal’ of Bronze. Another link which I was so pleased to find was that Cornwall’s Patron Saint – St Piran – was actually born and brought up on Cape Clear – the island we look out to across Roaringwater Bay. Read all about it here.

The little church at Perranzabuloe in Cornwall (now inundated by sand) marks the spot where St Ciarán from Cape Clear landed to start his mission. Because of a difference in the Irish and Cornish languages, he became known as St Piran over there. He lived to the age of 208!

Stirring up those links led to my life being taken over in the summer of this year by organising (together with Ann Davoren and the team at the West Cork Arts Centre) an exhibition of the work of three contemporary Cornish artists which was held in Uillinn, Skibbereen’s amazing new gallery. The exhibition ran with the title of West meets West and heralds future collaborations and visits to Cornwall by West Cork artists. This link opens the series of posts that report on all this.

My time here in West Cork – and in Ireland – has heightened my interest in all things medieval, particularly architecture. Finola has written a highly researched and detailed series on the Irish Romanesque style, and our travels to carry out this research have been enjoyable and instructive. I have taken a liking to High Crosses, most of them probably over a thousand years old. They are always found in the context of fascinating early ecclesiastical sites. If you want to know more, have a look at the posts: so far we have explored Moone (above), Durrow (below), Monasterboice, and Castledermot. There are many more to add to this list – and to keep us busy over the next few years.

That’s quite enough for one post! It would be possible to write several on how we have been inspired by our explorations in search of material. Somehow, though, our hearts always come back to our very own piece of Irish soil: Nead an Iolair (Nest of the Eagles). Here it is, and here are the eagles flying over it! You’ll find more about them here.
