Arch #2



The second in an occasional series of arches; another island and another rock. This graceful arch is of Torridonian (old red) sandstone and is on the lovely isle of Tanera Beg in the Summer Isles. These lie at the mouth of Loch Broom in the north west of Scotland.

Arch #1



There are few sights more satisfying on a sea kayaking trip than an arch. I especially like ones you can paddle through. You really feel you are interacting with environment when you are under an arch. This one just invited us through. I think part of the attraction is that, just like us, an arch is mortal and will not be there forever.

To my mind nothing defines the interface between land and sea so well as an arch.

This magnificent arch is at the foot of Bloodstone hill on the island of Rum. Green agates are found in this rock. They contain little tiny red flecks of iron, and it is these that give the stone and the mountain its name.

The geology here is very complex, Bloodstone Hill lies at the boundary of granite and Torridonian sandstone. It is also covered with sedimentary conglomerate rocks containing igneous rocks from the eruption which formed the Cuillin of Rum. These sedimentary rocks are then covered with lava flows that are younger than the Rum eruption and which probably came from the later Mull eruption to the south.



If you look carefully at the top slopes of Bloodstone Hill, you can see where these lavas have flowed over the top of the hill and started to run down ancient river valleys. The lava solidified before it got to the sea and has left steep escarpments.

Indoor echoes of dripping water.



How prophetic was yesterday's post? I went to bed and dreamed of dripping Hebridean caves and woke to a steady drip somewhat closer to home. Last night Glasgow was lashed by winds up to force 9 and torrential rain. My roof was damaged and the rain has driven in.



Today's BBC's synoptic chart shows more winds of up to force 9 again will hit Glasgow and the Clyde. I would normally have gone windsurfing at Troon but I have a dental abscess at the moment. A sore head and a leaking roof are not a good combination. I must cheer myself with another summer memory.



PS Sunday 21:25 hrs. Wind and rain are increasing; strategic pots have been placed. Why oh why did I post about dripping water?!!

Subterranean echoes of dripping water.



As I paddled alone deep inside the cave, the sounds of the outside world gradually diminished. There was only the gentlest of swell and it hardly disturbed the calm at the back of the cave. After some moments my ears and eyes gradually adjusted to the noises and colours in the cave. There was the most wonderful sound of water dripping from the darkness of the cave roof into the sea beside me. The drips echoed round walls of iridescent reds and greens above a turquoise sea.



This is sea kayaking

Easdale buoys, fools and slates.



We took the Aleut Sea II out to the small island of Easdale that lies off the west coast of Argyll's Island of Seil. We landed on a beach of dark grey slates.



These buoys adorned a building of slate.



Climbing to the top of the island, we saw the great flooded slate quarries that have hollowed out this island's heart. The photo shows the breaches in the quarry wall that a tidal wave made during the great storm of 1881. At low tide the walls are still complete and locals try and catch the fish that have been trapped inside. The quarries go down to 80m below sea level. At their peak of production, in the 1860s, Easdale slates were exported to, Australia, New Zealand, the Caribbean, the United States, Nova Scotia, Newfoundland and Labrador.



Easdale slate is very fine grained but it contains little cubes of iron pyrites or "fool's gold". If you break the slate open the crystals shine brightly but they soon rust when exposed to the air. If you live in one of the above countries and you come across a building with a slate roof have a look and see if the slates came from the little island of Easdale.

After the collapse of their industry, the miners and their families followed their slates to Australia, New Zealand........ They carried the names of their families and villages with them.

Cuan Sound.



One of the most fun things to do in a sea kayak is to play in a nice tidal race. Between the islands of Seil and Luing lies the narrow Cuan Sound.



The flood tide is compressed as it travels up the great Sound of Jura and through Shuna Sound until it squirts out through the Cuan sound at up to 15km/hour.



As the tide turns the flow reverses and unlike the tide in more open waters it reaches maximum speed very shortly after turning.



In a recent post about wind farms Iona commented that tidal power is efficient and less intrusive. The Cuan Sound is one of the sites under consideration for a tidal barrage or fence to generate electricity.

We enjoy the Cuan Sound while it is still a free ride through!

Psalm 59 on Scarp



In a recent post I mentioned the remote island of Scarp off the west coast of Harris in the Outer Hebrides. After the failure of rocket mail its inhabitants were finally connected to the mainland by submarine telephone in 1947. It was destroyed by a storm in 1970 and the GPO refused to replace it. The islanders finally evacuated Scarp in 1971. By tradition they had left a Bible in each house. By the summer of 2006 the houses were in a sorry state after 35 years of winter storms. In one house pages of a bible had blown about the windowless room.



Some days later we met the gentlemen in the centre of the photograph on Canna in the Inner Hebrides. It turned out he had grown up on Scarp until his family emigrated to Glasgow. We had a book about Scarp Hebridean Island, Memories of Scarp. He was able to identify many of the individuals in old photographs reproduced in the book.
