Hello Don, thanks for your comments, your'e too kind. As for the twinning - I don't know, it's very strange isn't it? Maybe one could call it 'inverse parallax twinning of nth dimensional matter'? Who knows. ;-)
All I know is it creeps me out somewhat. I can't look at the picture for too long - it's starts to twist my head ! Gives me the feeling that if I took a run at it and dived in, I would keep on falling for eternity...
Woah! Scary.

Mike, thanks so much for showing your photos of the Cairngorms. It looks like a truly spectacular place, and I can understand why it is so inspiring for you.

Thank you Michael, and I'm pleased you like my scenic photo's.

14mm x 8mm x 7mm
Same specimen as above showing the termination in more detail. I did have one of these pale yellow beryls cut one time, after I first came across them in the mid 1990's. The gems were small but rather beautiful, and not far off a true heliodor for colour. Unfortunately the one I kept I lost during a house move ten years ago -_-
I think I've got a slide photo of it somewhere, I'll try to find it and scan it. |

I found a few lumps of this unusual rock in one place, just lying on the ground. It looks like granite but there is almost no quartz in it - comprising an equigranular mass of greenish beryl and pink feldspar (don't know if the feldspar is microcline or orthoclase). Beryl crystals were found in the vicinity, from thin pegmatite veins. |

Only the inner part is truly pegmatitic; the outer two parts of the vein are composed of either fine-grained granite, or aplite rock. But free grown crystals of quartz for example are very rarely found in these veins. |

Cairngorm minerals..
| Description: |
Smoky Quartz + Microcline
Ben a' Bhuird, Cairngorm Mountains, Grampian Region, Scotland.
85mm x 53mm x 30mm
Specimen of small smoky quartz crystals on microcline. The larger microcline crystal in the centre is 14mm x 10mm. There is also a crystal of muscovite mica (6mm) on the right-hand side.
The smoky quartz is transparent. This specimen and the next one came from a thin pegmatite vein cavity in a granite boulder. Collected 1994. |

Thanks Vic, and just for you, here's a picture of Shelter Stone Crag. I did find some quartz crystals there near the top. I'll post them next time.
Best Regards,

Quartz
Shelter Stone Crag, Caingorm Mountains, Grampian Region, Scotland, UK
70mm x 35mm x 30mm
A fairly large but rough looking quartz crystal. It is somewhat translucent and not smoky, and appears to have an overgrowth or second generation of quartz. Found this and several small crystals near the top of Shelter Stone Crag, by carefully climbing down a 'bottomless' gully a short distance (not the gully in the previous photo). Couldn't do much poking about as I was acutely aware of the sickening drop below me, and the possibility of climbers somewhere below. |

| The cave was certainly real, but inside there was no trace of any crystals, not even any quartz on the roof or walls. The only good thing about it, apart from the satisfaction of actually getting there, was the rich variety of flora outside it, and the view. |

| Description: |
View looking out of the cave to the other side of the valley, where the 'Shelter Stone ' lies - it is a huge flat boulder which climbers and bivouac enthusiasts have 'camped' beneath, since climbing started around here.
For my next trick, from the so-called crystal cave I decided to take a short-cut to the top of the cliff via a likely looking gully around the corner. Not one of my better ideas - I seemed to have forgotten that gullies usually become steeper and steeper the higher up you go! Carrying a large heavy rucksack and wearing big boots I found myself astride between rock walls in the steepest part of the gully (which was about 70 degrees) and wishing I wasn't there! But I was committed and knew that the only way to do it was to focus my mind and go for it, which I did. Fortunately the difficulties were short, the angle eased off, and I was mighty relieved to top out on the nice flat grassy plateau, for a not very well-deserved rest!!
Lesson learned?? Not really, just part of the experience, but I'll certainly remember it, which is the main thing. -_- |

All your trouble was worth it Mike! You have a story to tell. Thank you for taking us along your journey. I wish I could join you on an outing or two but doubt whether I would hold out. Is there trout in those lochs?

Thank you Pierre; I could write a few more tales about my exploits, plenty on the Isle of Skye for example. I might write some during the holidays..
I am quite confident there are trout in those lochs, they seem to lurk in most UK waters, even in unlikely places. Also salmon and sea trout will make their way up the rivers a fair way into the mountains. I seem to recall seeing fishermen by Loch Avon some time in the past.
| Description: |
Lochan Uaine, about 1.5km southeast of Ben Macdui in the Cairngorms, one of the highest lochans (small lake) in the UK at over 950m above sea level. But even I was surprised to see icebergs floating on it, in late June!! Don't know for sure if it contains trout, but I bet it does.

Mike,
That is a wonderful picture of Mer de Glace. It looks like it was taken from an airplane or helicopter. Like Pierre, I don' t think that I could climb with you. I think I am getting symptoms of altitude sickness just looking at your picture. :-)

Thanks Tobi and Don!
Mind you Don, this was over twenty years ago and I would certainly struggle myself to climb up to places like this nowadays..
Here is another photo taken from the same position at the same time. We didn't actually manage to get to the top of Le Aiguille Verte (4122m), much to my chagrin - ran out of time though another couple of hours would have done it. By the time we got back down to the Courvercle Hut we'd been on the mountain for sixteen hours! Much too slow - we were climbing roped together and it wasn't really necessary most of the time. Also the climbing was 'merde' if you'll pardon the expression; very very steep and very very loose. Mind, that's what you get late on in the season without the snow to consolidate the rocks. On the other hand you can't see the rocks if there is snow cover - better for climbing but not so good for mineral collecting!

Right then; here we go...
In July 1991 I drove out from Yorkshire with two friends from a climbing club to camp for three weeks at Argentiere, near Chamonix, France. We met up with some more friends from the climbing club at the campsite. I had visited the same area when I was a kid of fifteen (1979) but didn't do any climbing at that time...
Being a newbie to Alpine climbing I tagged along with my two friends on my first proper climb - the NW couloir of Aiguille du Chardonnet (TD), involving walking from the campsite up to the Albert Premier Hut by the Glacier du Tour, bivouac near the Hut (couldn't afford to actually stay in it). Then a pre-dawn start across the glacier to start of the route, climb the route which was steeper and much more impressive than the Scottish winter routes I was used to! The upper part of the climb had a 70m pitch of solid smooth ice at an angle of about 70 degrees, in a gully 10m wide. Luckily for me I didn't lead that pitch, I was scared enough as it was. Once at the top of the route and only about 200m below the summit, we could see storms approaching so unfortunately didn't get to the summit. Instead we followed the descent route and back down to the glacier and the hut to pick up our bivi gear which we'd left nearby, then back down to the campsite.
After that, I decided that climbing these mountains was not much more difficult than climbing the Cuillins on the Isle of Skye, in winter - just bigger that's all! So I reckoned I was capable of climbing some of them solo, I just had to pick the right mountain and the right routes to climb them; and there were plenty of routes that were easier than the one I'd just climbed...
I determined to go climb some mountains with lumphammer and chisels and see what happened!
I have combined photo's from 1991, 1992 (slide) and 2005 (digital camera) to describe the single event of climbing the Aiguille du Moine and finding smoky quartz crystals.
| Description: |
From Chamonix I got the train to Montenvers, which is by far the easiest way to get to the Mer de Glace; which I needed to walk along to get to the Aiguille du Moine. It's a very popular spot for visiting tourists and climbers passing through..

Once on the glacier (Mer de Glace) it is several kilometres walk to some more ladders, to get off the glacier and up the path to the Courvercle Hut below the Aiguille du Moine. The glacier is 'dry' this low down at this time of year so is mostly easy to walk on - you can see the objective dangers (crevasses) and avoid them. A refreshing cold breeze blows down the valley, otherwise it would be hot under the summer sun.

Then the climbing got even harder..
