They left the cart in a parking area and walked out through the woods. A low thunder coming from the river. It was a waterfall dropping off a high shelf of rock and falling eighty feet through a gray shroud of mist into the pool below. They could smell the water and they could feel the cold coming off of it. A bench of wet river gravel. He stood and watched the boy. Wow, the boy said. He couldnt take his eyes off it.

He squatted and scooped up a handful of stones and smelled them and let them fall clattering. Polished round and smooth as marbles or lozenges of stone veined and striped. Black disclets and bits of polished quartz all bright from the mist off the river. The boy walked out and squatted and laved up the dark water.

The waterfall fell into the pool almost at its center. A gray curd circled. They stood side by side calling to each other over the din.

Is it cold?

Yes. It's freezing.

Do you want to go in?

I dont know.

Sure you do.

Is it okay?

Come on.

He unzipped his parka and let it fall to the gravel and the boy stood up and they undressed and walked out into the water. Ghostly pale and shivering. The boy so thin it stopped his heart. He dove headlong and came up gasping and turned and stood, beating his arms.

Is it over my head? the boy called.

No. Come on.

He turned and swam out to the falls and let the water beat upon him. The boy was standing in the pool to his waist, holding his shoulders and hopping up and down. The man went back and got him. He held him and floated him about, the boy gasping and chopping at the water. You're doing good, the man said. You're doing good.

They dressed shivering and then climbed the trail to the upper river. They walked out along the rocks to where the river seemed to end in space and he held the boy while he ventured out to the last ledge of rock. The river went sucking over the rim and fell straight down into the pool below. The entire river. He clung to the man's arm.

It's really far, he said.

It's pretty far.

Would you die if you fell?

You'd get hurt. It's a long way.

It's really scary.

They walked out through the woods. The light was failing. They followed the flats along the upper river among huge dead trees. A rich southern wood that once held may-apple and pipsissewa. Ginseng. The raw dead limbs of the rhododendron twisted and knotted and black. He stopped. Something in the mulch and ash. He stooped and cleared it away. A small colony of them, shrunken, dried and wrinkled. He picked one and held it up and sniffed it. He bit a piece from the edge and chewed.

What is it, Papa?

Morels. It's morels.

What's morels?

They're a kind of mushroom.

Can you eat them?

Yes. Take a bite.

Are they good?

Take a bite.

The boy smelled the mushroom and bit into it and stood chewing. He looked at his father. These are pretty good, he said.

They pulled the morels from the ground, small alien-looking things that he piled in the hood of the boy's parka. They hiked back out to the road and down to where they'd left the cart and they made camp by the river pool at the falls and washed the earth and ash from the morels and put them to soak in a pan of water. By the time he had the fire going it was dark and he sliced a handful of the mushrooms on a log for their dinner and scooped them into the frying pan along with the fat pork from a can of beans and set them in the coals to simmer. The boy watched him. This is a good place Papa, he said.

They ate the little mushrooms together with the beans and drank tea and had tinned pears for their desert. He banked the fire against the seam of rock where he'd built it and he strung the tarp behind them to reflect the heat and they sat warm in their refuge while he told the boy stories. Old stories of courage and justice as he remembered them until the boy was asleep in his blankets and then he stoked the fire and lay down warm and full and listened to the low thunder of the falls beyond them in that dark and threadbare wood.

He walked out in the morning and took the river path downstream. The boy was right that it was a good place and he wanted to check for any sign of other visitors. He found nothing. He stood watching the river where it swung loping into a pool and curled and eddied. He dropped a white stone into the water but it vanished as suddenly as if it had been eaten. He'd stood at such a river once and watched the flash of trout deep in a pool, invisible to see in the teacolored water except as they turned on their sides to feed. Reflecting back the sun deep in the darkness like a flash of knives in a cave.

We cant stay, he said. It's getting colder every day. And the waterfall is an attraction. It was for us and it will be for others and we dont know who they will be and we cant hear them coming. It's not safe.

We could stay one more day.

It's not safe.

Well maybe we could find some other place on the river.

We have to keep moving. We have to keep heading south.

Doesnt the river go south?

No. It doesnt.

Can I see it on the map?

Yes. Let me get it.

The tattered oilcompany roadmap had once been taped together but now it was just sorted into leaves and numbered with crayon in the corners for their assembly. He sorted through the limp pages and spread out those that answered to their location.

We cross a bridge here. It looks to be about eight miles or so. This is the river. Going east. We follow the road here along the eastern slope of the mountains. These are our roads, the black lines on the map. The state roads.

Why are they the state roads?

Because they used to belong to the states. What used to be called the states.

But there's not any more states?

No.

What happened to them?

I dont know exactly. That's a good question.

But the roads are still there.

Yes. For a while.

How long a while?

I dont know. Maybe quite a while. There's nothing to uproot them so they should be okay for a while.

But there wont be any cars or trucks on them.

No.

Okay.

Are you ready?

The boy nodded. He wiped his nose on his sleeve and shouldered up his small pack and the man folded away the map sections and rose and the boy followed him out through the gray palings of the trees to the road.

When the bridge came in sight below them there was a tractor-trailer jackknifed sideways across it and wedged into the buckled iron railings. It was raining again and they stood there with the rain pattering softly on the tarp. Peering out from under the blue gloom beneath the plastic.

Can we get around it? the boy said.

I dont think so. We can probably get under it. We may have to unload the cart.

The bridge spanned the river above a rapids. They could hear the noise of it as they came around the curve in the road. A wind was coming down the gorge and they pulled the corners of the tarp about them and pushed the cart out onto the bridge. They could see the river through the ironwork. Below the rapids was a railroad bridge laid on limestone piers. The stones of the piers were stained well above the river from the high water and the bend of the river was choked with great windrows of black limbs and brush and the trunks of trees.

The truck had been there for years, the tires flat and crumpled under the rims. The front of the tractor was jammed against the railing of the bridge and the trailer had sheared forward off the top plate and jammed up against the back of the cab. The rear of the trailer had swung out and buckled the rail on the other side of the bridge and it hung several feet out over the river gorge. He pushed the cart up under the trailer but the handle wouldnt clear. They'd have to slide it under sideways. He left it sitting in the rain with the tarp over it and they duckwalked under the trailer and he left the boy crouched there in the dry while he climbed up on the gastank step and wiped the water from the glass and peered inside the cab. He stepped back down and reached up and opened the door and then climbed in and pulled the door shut behind him. He sat looking around. An old doghouse sleeper behind the seats. Papers in the floor. The glovebox was open but it was empty. He climbed back between the seats. There was a raw damp mattress on the bunk and a small refrigerator with the door standing open. A fold-down table. Old magazines in the floor. He went through the plywood lockers overhead but they were empty. There were drawers under the bunk and he pulled them out and looked through the trash. He climbed forward into the cab again and sat in the driver's seat and looked out down the river through the slow trickle of water on the glass. The thin drum of rain on the metal roof and the slow darkness falling over everything.
