How Mara reads a shaft of light

The Canopy Line starts in the dark for one reason, and the reason is a gap in the canopy about forty metres above the first bend, roughly the size of a door. On a clear morning the sun finds that gap at 07:29 and puts a single column of light on the forest floor for nine minutes, sometimes eleven if the air is full of mist to hold it. Then the sun moves, the gap closes, and the forest goes back to being a forest.

Getting a group of eight standing under that column at the right second is a craft. Mara is the only one of us who has it, and this is an attempt to write down what she does, made with her permission and her warning that most of it cannot be written down.

Mara does not look up. She reads the floor. Where the moss is a shade paler, the light has been landing for years and has bleached it. Where the ferns lean, they lean toward the column, because that is where the light comes from and a fern is a machine for finding light. She walks the group to a place that looks like nothing, a patch of floor like any other, and asks everyone to stop talking, and then, more or less to the second, the forest switches on.

The three things she checks

1. Cloud at the horizon, not overhead. Everyone looks up to see if it is clear and up is the wrong direction. A band of high cloud to the east, invisible from the trailhead, delays the shaft by minutes and can cancel it outright. Mara reads it from the road on the drive in, where there is a view east across the valley, and she knows by the time she parks whether the morning is a maybe or a yes.

2. Mist on the floor. The more there is, the longer the column stays visible, because you are seeing the light in the air and not only where it lands. A dry morning gives you a bright patch on the moss for nine minutes. A misty one gives you a room made of light that you can walk into.

3. Wind. A moving canopy makes the shaft wander. On a still morning the column stands where it has always stood. On a breezy one it swings a metre either way, and Mara would rather have people standing still while it comes to them than chasing a patch of light around the floor like children after a torch beam.

What she will not tell you

There is a fourth thing and she does not name it. Something about the smell of the air at the gate, or the sound the creek is making, or the way the birds are or are not going. She has stood at the first bend and said not today with a clear sky and no wind and been right. When pressed she says it is the same as knowing when bread is done, and then she stops talking about it.

You do not chase light. You are already standing where it is going to be.

None of this is in a book. She learned it by standing in the wrong place for two seasons and writing down, every morning, where the light actually went. The notebook exists. It has not been shown to anyone. When she stops walking the line, whoever takes it will get the notebook and two seasons of standing in the wrong place, and then they will have it too, or they will not.

The nine minutes

What actually happens is undramatic and then it is not. The floor gets slightly lighter, the way it does when a cloud moves. Then a line appears in the mist, a hard edge of brightness from somewhere above, and it thickens, and the floor inside it goes from green to gold, and there is a column of light the width of a room standing in the forest with eight people inside it. Nobody says anything. Mara stands at the edge and watches the people, not the light.

It goes the way it came, from the top down, and for a minute afterward nobody moves. Then someone laughs, and the walk goes on, and the rest of the morning is very good and everyone knows the best part has already happened.

A note for photographers

You will not get it. Not the way it is. The camera turns it into a beam and it is not a beam, it is a room, and the difference is the difference between a picture of a shaft and standing in one. Put the camera down for the first minute, be inside it, and then do what you like with the other eight. The people who take this advice come back. The people who spend the nine minutes behind a screen mostly do not, and they are right not to, because they were not there.

If it does not come

One morning in four it does not. Cloud to the east, or the air too dry to hold it, or the fourth thing. Mara says so at the first bend, plainly, and the walk goes on, and it is a different walk and a good one. Nobody gets their money back and nobody asks. The shaft is not something we sell. It is something we stand in the right place for.
