Down the ice valley directly south of the pass, Nirgal could see a huge crumpled white plateau, where glaciers poured in from the surrounding high basins to meet in a great confluence. This was Concordiaplatz, they told him. Four big glaciers met, then poured south in the Grosser Aletschgletscher, the longest glacier in Switzerland.
Nirgal moved down the terrace to its end, to see farther into this wilderness of ice. At the far end he found that there was a staircase trail, hacked into the hard snow of the south wall where it rose to the pass. It was a path down to the glacier below them, and from there to Concordiaplatz.
Nirgal asked his escorts to stay in the station and wait for him; he wanted to hike alone. They protested, but the glacier in summer was free of snow, the crevasses all obvious, and the trail well clear of them. And no one else was down there on this cold summer day. Nevertheless the members of the escort were uncertain, and two insisted on coming with him, at least part way, and at a distance behind—”just in case.”
Finally Nirgal nodded at the compromise, and pulled on his hood, and hiked down the ice stairs, thumping down painfully until he was on the flatter expanse of the Jungfraufirn. The ridges that walled this snow valley ran south from the Jungfrau and the Monch respectively, then after a few high kilometers dropped abruptly to Concordiaplatz. From the trail their rock looked black, perhaps in contrast to the whiteness of the snow. Here and there were patches of faint pinkness in the white snow— algae. Life even here— but barely. It was for the most part a pure expanse of white and black, and the overarching dome of Prussian blue, with a cold wind funneling up the canyon from Concordiaplatz. He wanted to make it down to Concordiaplatz and have a look around, but he couldn’t tell whether the day would give him enough time or not; it was very difficult to judge how far away things were, it could easily have been farther than it looked. But he could go until the sun was halfway to the western horizon, and then turn back; and so he hiked swiftly downhill over the firn, from orange wand to orange wand, feeling the extra person inside him, feeling also the two members of the escort who were tagging along some two hundred meters behind.
For a long time he just walked. It wasn’t so hard. The crenellated ice surface crunched under his brown boots. The sun had softened the top layer, despite the cool wind. The surface was too bright to see properly, even with sunglasses; the ice joggled as he walked, and glowed blackly.
The ridges to left and right began their drop. He came out into Concordiaplatz. He could see up glaciers into other high canyons, as if up ice fingers of a hand held up to the sun. The wrist ran down to the south, the Grosser Aletschgletscher. He was standing in the white palm, offered to the sun, next to a lifeline of rubble. The ice out here was pitted and gnarly and bluish in tone.
A wind picked at him, and swirled through his heart; he turned around slowly, like a little planet, like a top about to fall, trying to take it in, to face it. So big, so bright, so windy and vast, so crushingly heavy— the sheer mass of the white world!— and yet with a kind of darkness behind it, as of space’s vacuum, there visible behind the sky. He took off his sunglasses to see what it really looked like, and the glare was so immediate and violent that he had to close his eyes, to cover his face in the crook of his arm; still great white bars pulsed in his vision, and even the afterimage hurt in its blinding intensity. “Wow!” he shouted, and laughed, determined to try it again as soon as the afterimages lessened, but before his pupils had again expanded. So he did, but the second attempt was as bad as the first. How dare you try to look on me as I really am! the world shouted silently. “My God.” With feeling. “Ka wow.”
He put his sunglasses back on his closed eyes, looked out through the bounding afterimages; gradually the primeval landscape of ice and rock restabilized out of the pulsing bars of black and white and neon green. The white and the green; and this was the white. The blank world of the inanimate universe. This place had precisely the same import as the primal Martian landscape. Just as big as it was on Mars, yes, and even bigger, because of the distant horizons, and the crushing gravity; and steeper; and whiter; and windier, ka, it pierced so chill through his parka, even windier, even colder— ah God, like a wind lancing through his heart: the sudden knowledge that Earth was so vast that in its variety it had regions that even out-Marsed Mars itself— that among all the ways that it was greater, it was greater even at being Martian.
He was brought still by this thought. He only stood and stared, tried to face it. The wind died for the moment. The world too was still. No movement, no sound.
