Seventy-one on the truck thermometer at five-forty. Cal turned the key and the diesel caught on the second try. Beside him, Nora pulled her hair through an elastic without looking, the gesture so practiced her hands seemed borrowed from someone older. She had coffee in a thermos she'd filled before he was up.
They drove east on the two-track toward the Willow Creek pasture, windows down. The air already carried heat in it, dry and close against his forearms, the kind of warmth that used to mean mid-morning. Smoke haze sat on the Crazies, a pale band smudging the ridgeline. Bitterroot fires, probably. She didn't look at it and neither did he.
"Check the panels first," he said. "Then the box."
She nodded.
The solar pump station sat on a rise above the spring. Two panels angled south, a black poly line running downhill to the stock tank. Nora checked the meter on the junction box, tapped the float valve, walked the line looking for leaks. He watched her boots on the hardpan. She moved the way he'd taught her but quicker, lower, her weight already shifting before she reached each connection point.
He walked to the spring box and lifted the lid. Water clear but thin, a finger's width across the weir where it used to run three. He held his hand in the flow and counted. His father had shown him this: seconds to fill a cupped palm. But his father's count had been calibrated to August, the annual low. This was July seventh.
"Flow's down," he said when she came back.
"From last week?"
"From last week."
She looked at the weir, then at the tank. Two-thirds full. She didn't ask how long.
They drove to the upper pasture and got out into the grass. It came to his shins, mostly blue grama now, fine-stemmed and already heading out. Ten years ago this ground had been western wheatgrass to his belt. His father would have called this pasture overgrazed. The species had shifted underneath the name, the same ground growing something else entirely, and the carrying capacity went with it.
"See the seed heads," he said. "Grama sets seed low. That means it's done for the year. You move cattle off when you see that."
Nora crouched and ran her fingers through the stems. Her hands were brown, nails cut short. A folded paper in her back pocket, creased along its lines, the edge of a blue letterhead above the denim. He looked at the grass.
"Your grandpa watched for wheatgrass heading out. That was his signal. But the wheatgrass is mostly gone from up here."
"When did it go?"
He thought about it. "Not all at once. You just notice one spring it's not what you're seeing anymore."
Along the fence line, cheatgrass had cured to a dull reddish-purple, seed heads barbed and brittle.
"That was done three weeks ago," Nora said. She touched a stem and it broke between her fingers. "April it was green. Six weeks, maybe."
He looked at her. She was right, and she'd said it before he had.
"Cut their mouths if they try," he said.
She stood and looked across the pasture the way he'd taught her, near ground to middle distance to hills. Sixty-two pair out there, dark shapes against the tan, bunched in loose groups with too much space between them. The smell reached him when the wind shifted, warm hide and dust and the sour-sweet breath of animals working through dry forage. A calf bawled once and the sound carried flat across the open ground. His father had run a hundred and thirty on this grass and called it conservative.
"We'll push them down to the creek bottom. Still some green along the water."
They walked back to the truck. The sun was full above the hills now and heat pressed on his neck, his shoulders through his shirt, the tops of his ears. Grasshoppers cracked up from the stems around their boots. Nora's phone buzzed in her pocket. She silenced it without looking.
He started the engine. They drove toward the cattle, dust rising behind them in a column that hung motionless in the still air, then slowly fell.
"Take the south side," he said. "Push them easy. Couple pairs like to hang back near those rocks."
She was out before he'd fully stopped, moving toward the herd with her shoulders loose and her weight forward. The cattle were already shifting, ears up, heavy heads turning. A cow near the front lowed and her calf pressed against her flank. The herd smell thickened as he got closer, manure and heat and the dry grass crushed under their hooves.
He cut the engine and stepped out. The truck ticked behind him. Nora was thirty yards ahead now, angling south, and the cattle were beginning to move. He pulled his hat down against the light and walked toward the north side of the herd. Between them, the animals stirred, already drifting toward the creek bottom.
