When I'm filling notebooks I'm trying to pin down what I'm really interested in and to find those details that are so hard to come by, details that I can look at and believe are right on the mark. Things which bring a novel to life. They can take a while to come.

WE DASH THE BLACK RIVER, ITS flats smooth as stone. Not a ship, not a dinghy, not one cry of white. The water lies broken, cracked from the wind. This great estuary is wide, endless. The river is brackish, blue with the cold. It passes beneath us blurring. The sea birds hang above it, they wheel, disappear. We flash the wide river, a dream of the past. The deeps fall behind, the bottom is paling the surface, we rush by the shallows, boats beached for winter, desolate piers. And on wings like the gulls, soar up, turn, look back.

In climbing, being first-rate is part of the whole enterprise. The important climbers want to be the first man up the mountain, the one who put up the first route. You're usually only remembered if you put up the first route on a very important climb. The route might even be named after you. That's a kind of glory.
