Generations of geology students have swarmed over his unconformity on the way to the Cock of Arran,.

We made our way out of Loch Ranza and turned north along...

...the Newton shore where we chose to stop for second breakfast near the site of a considerable nonconformity.

Just below the wreck of this old boat (which has seen better days) lies an interesting geological feature,.It attracted the interest of the 18th century Scottish geologist James Hutton. He observed dipping old metamorphic rocks which were immediately overlain by gently sloping layers of much younger sedimentary rocks. There was no evidence of any intermediary rocks between the layers despite them being separated by 160 million years. Hutton used this unconformity to deduce that the underlying metamorphic rock had been created, metamorphosed, (altered by great forces) then uplifted and eroded before the later sedimentary rocks were overlain. Lastly, the two layers were then further uplifted then eroded to expose their junction on what is now Newton shore. He deduced from all this that the World was much older than had been previously thought.

Generations of geology students have followed Hutton to swarm all over his unconformity.

Leaving the unnconformity we passed the Fairy Glen on our way north.

This rock pippit was hopping between great...

...priapic boulders of conglomerate...

... which lay on the old red sandstone of the Cock of Arran.

Anchors aweigh at Lochranza castle.

Although Lochranza castle has stood since  it was built by the MasSweens as a two storey hall house in the mid 13th century...

 ...it was heavily modified by the Mongomeries in the 16th century to become a tower house. Indeed this is not even the original door, which was initially on the other side of the castle.

 The interior is well worth exploring and it is fun to try and work out what function the various parts of the castle had served.

 Some of the stairways are still open so it is possible to climb to some of the upper levels.

 Helpful plaques highlight features of the castle's construction and history.

Although the sun shines in now, originally the interior would have been very dark.

 Some light now spills into this store but the claustrophobic prison was still in complete darkness so...

 ...it was a relief to escape through the tiny door to...

...the brightness of the day outside. It would have been nice to stay in this wonderful location for second breakfast but a bitterly cold wind had sprung up and not even...

...this wonderful old anchor could hold us there. It was time to move on to an unconventional alternative....

A cuckoo in every corrie... a cacophony round the castle..

 The peace of our crossing to Loch Ranza in NW Arran was temporarily broken by the rumble of the MV Loch Tarbert's engines. She was running on the route from Lochranza to Claonaig on Kintyre. She soon passed on and silence returned....well not quite. The eerie calls of the divers in mid-channel were replaced by a cacophony of cuckoos calling from the corries..

There seemed to be at least four cuckoos. One in Glen Catacol to the south. One in the Coille Mor corrie, high above Lochranza village,...

...one from a corrie high on the slopes above the NE side of Loch Ranza and...

 ...at least one more, high in one of the corries above Glen Chalmadale. What an aural welcome the cuckoos made as we paddled into misty Loch Ranza as these...

 ...two yachts were preparing to leave. It was with some satisfaction that I told their crew we had been up early and had already crossed from Kintyre!

We continued up Loch Ranza as far as the peninsula upon which...

 ...the ancient walls of...

 Lochranza Castle had stood for centuries..

Like Skipness Castle across the Kilbrannan Sound (which we had passed the previous day), Lochranza Castle had originally been built by the MacSweens to control the north end of the Kilbrannan Sound. With the sound of the Lochranza cuckoos echoing round the hills, we decided to stop and explore....

Forty minutes in the natural theatre of the Kilbrannan Sound.

In the middle of the Kilbrannan Sound  the fog slowly began to clear and we could at last see which way we were going.

This guillemot seemed surprised to see us at it emerged from a thick patch of fog but it not been responsible for the haunting calls that came from an undefinable direction in the mist. Those had come from an unseen diver.

 Slowly the mountains of Arran began no emerge from the fog and we could...

...identify the hills to the south of Catacol.

 We now experienced one of the most wondrous sights we have ever experienced while crossing to Arran.
Slowly the small gap in the fog opened revealing clear blue sky to the south.

  It was as if a celestial zipper was being undone as the fog...

 ...steadily pulled back revealing....

 ...more and more of the...

 ...mountainous west Arran coast.

As we were paddling at about the same speed and direction as the receding edge of the fog, it was like being in a day of two halves and we were on the dividing line.

 At first we continued paddling in the shade but ever so slowly the edge of the fog...

 ...pulled away in front leaving us...

in full sun. We were speechless with wonder and appreciation of this natural show in the theatre of the Kilbrannan Sound. Any applause would have been both unnecessary and would have broken the spell that held us captivated on this unforgettable crossing. From the time that a peak first loomed out of a break in the fog, to when we finally entered full sunshine, this natural performance lasted for forty minutes. Those special forty minutes will last in our memories for ever.
