A trip to the theatre

Hauling out
This haul-out went relatively smoothly, but not too smoothly (that would be boring). The local haul-out wizard and myself used van power, muscle power and ultimately an interesting grapnel+outboard engine technique to get the trailer into about 6 feet of water. Briongloid was towed on with an anchor laid out astern to check her way (boats don't have brakes!). Unfortunately, she landed just slightly off-centre on the trailer, missing the trough that normally holds her keel. I did try to fix this (setting a personal speed record for time taken to change into a wet-suit), swimming down to hold the trailer and kick the keel (it has worked before), but she was already too well settled (we had used the van/rope combination to haul the trailer higher on the slip, not a reversible procedure), but ultimately, it was not serious balance problem, and had the advantage of allowing us to clean beneath the keel.

Checking the weather
My luck was in, and my sighting tube was still calibrated; Jupiter appeared almost immediately in my field of view, and seconds later was focused perfectly. I could see the bright disk of the giant himself, and four bright points almost in a line - the 4 largest moons, 1 to the left and 3 to the right*. Knowing the moons to be only a little smaller than Earth, the vast scale of Jupiter was obvious. As I watched, I realised that I could a dark reddish band running across Jupiter's disc, some distance south of the equator.
Standing beneath the glowing windows of my home on a chilly autumnal night, it boggled my mind to be looking at alien weather. Of course, I've seen pictures of Jupiter many times, but somehow, this was much more real. Just think...
- 70 minutes previously, the photons now hitting my eyes were leaving the roiling surface of our star
- 30 minutes previously, those same photons bounced off freezing cloud-tops in the very toxic upper atmosphere of a truly enormous planet, and off towards a tiny blue speck...
- ...where they whizzed down a plastic tube, bounced off two small curved mirrors, and into my eye.
* The informed reader, comparing my observations of cloud bands and moon positions with Jupiter's actual orientation might think I'm either observing while standing on my head or an Australian. Well, I'm innocent on both counts - a reflector telescope typically doesn't preserve up/down left/right.

Glacial Galtees
Serious frost foils local arachnid
Now, a weather front rolling in from the east has delivered the coup de glace; at dawn, a weak sun cast a rosy light on the Galtees, covered at last in a deep blanket of fresh snow, smooth and dangerous. I can resist anything - except tempation; packing for the mountains takes fifteen minutes. My walk starts in an oak wood, as fresh snow begins to fall, whitening a path that had been bare. Beyond the last trees, sheet ice makes the lower mountain treacherous and adds an extra frisson to fording streams. Higher, knee deep snow lies beneath an icy crust that nearly supports my weight. Unfortunately, I have no snow shoes; and so the going, on a trackless mountainside, is brutally hard.
Icy stream, the Galtees
Then, a devastating disappointment; reaching the slope that I wanted to sled down, blades of grass rising above the snow have collected thick sheaths of ice. They form an endless forest of finger-thick spikes, glittering like glass as the sun breaks through. Gorgeous, but totally un-sledgable. I am getting tired; the going is too hard, the snow too deep, the ground too rough; I need a way out. There is my own trail up, but even that will not be easy going. Suddenly, sunset seems all too close.
At exactly the right moment, walkers appear higher on the slope, moving very quickly and easily; the ground allows me only a waist up view, but I can see they have found a better way. More slogging gets me higher, to a mountain trail; here, the snow is well trodden, and at last I can walk easily, and look beyond my next step. After the slog of the deep snow off-trail, the relief is incredible. The air is very clear, and I can see a great distance over a completely frozen landscape. At this height, no stream can flow, and the only sound is the crunch of the snow beneath my boots and the whistle of an east wind carrying arctic overtones. It lifts and flips my improvised sled (a bodyboard) and numbs my face, so that when I call my wife, I stumble over my sibilants.
This high place is wild, beautiful, and killing cold; reluctantly, I turn to descend the path as the valley below sinks into shadow, muscles already two-thirds spent, fresh bruises darkening. I am exquisitely happy, intoxicated with the magic of deep winter in high places.
