The creek below Anthony Lake was running in September.
Reyes crouched where the water crossed exposed granite and put her fingers in and held them there until they ached. Then she climbed twenty meters to the lake and did the same thing, and the lake was warmer. So not surface overflow from the old mining dam. Subsurface, then — snowmelt banked in fractured rock through the winter and let out on a delay she had never tracked, because in nineteen Septembers on this ridge the creek had been dry every time.
She wiped her hand on her thigh and watched the water move over pale stone for a while.
Above the lake, subalpine fir had filled in the cirque. Dark green crowding the sheltered ground between rock faces, colonizing the north-facing pockets where snow used to hold into July. Twenty years ago that was open country — meadow grass, scree, a few whitebark pines bent permanent by the wind. The fir was shoulder-high now and thick, and the whitebarks above them were mostly gray snags, beetle-killed, standing among the ones still holding on. The living trees had cones this year. Small, purple-green, clustered high where she couldn't reach them.
She hadn't seen a Clark's nutcracker in the Elkhorns since 2068. The trees were fruiting for a bird that had left.
She stood and shrugged the pack back into place. The device in the inner pocket pressed against her spine through three layers of padding — same spot, same case, eleven years, charged off the panel folded into the top flap. The counter-map lived on that device and nowhere else. No copy in the church mesh, no cache in the treaty archive, nothing on anyone's personal storage. The map was wherever she was. When she wasn't somewhere, neither was it.
The trail down from the ridge followed the old Elkhorn Crest route, which the Forest Service maintained until 2041 and which had been maintained since by whoever walked it. Reyes walked it four times a year. The tread was good where she went and fading where she didn't, a record of her own passage written in packed dirt and cleared deadfall. At the second switchback she passed the mine tailings, rust-orange waste rock spilling out of an adit that somebody had sealed with concrete in the 1990s and that frost heave had unsealed sometime in the fifties. Water seeped from the opening now and stained the rock below it. She'd flagged it three years ago. Acid drainage, minor, seasonal. The kind of thing nobody was going to fix because nobody was left whose job it had been.
Below the mine the trail crossed a logging road that had been graveled once and was now two ruts through bunchgrass. She followed it south a quarter mile to the cache she kept in a culvert where the road crossed a dry wash. The culvert was half-buried in sediment and invisible from ten feet off.
The cache was open.
Not broken into. Opened. The sediment plug she'd shaped over the downstream end had been taken out carefully and put back carefully, but the compression was wrong — scooped instead of packed, and the fingermarks in it were smaller than hers.
Reyes sat back on her heels and looked at the culvert for a while. Then she reached in and pulled the case out. The relay node was still inside, a mesh transceiver the size of a deck of cards, solar-trickle-charged, sitting on the church frequency. She'd put it here to push her coverage into the upper Elkhorns, where the terrain blocked signal off the John Day plateau nodes. It was supposed to be passive. Receive and store.
She checked the log.
Naya had accessed it eleven days ago. Uploaded a packet through it to the church mesh — a packet Reyes hadn't authorized, from a device Reyes had given her, carrying thermal readings from four of the fourteen cold-reach sites Tam had surveyed and refused to release.
Not coordinates. Naya was careful about that. What she'd sent was a profile: four temperatures, four elevation bands, four seasonal timestamps, four substrate descriptions. Numbers cut loose from their locations and handed to the network as evidence that cold water still ran in the interior basin.
Reyes closed the case, put it back, rebuilt the plug the way she'd built it the first time. Then she sat down on the road with her back against the concrete lip and looked at the smoke standing over the Grande Ronde valley.
Numbers alone were survivable. Temperature, elevation, substrate — without locations they described a kind of place. Anybody in the church network who received them would know that somewhere in the Blues there was cold water. They wouldn't know where.
Except that Oliver had been building a spatial model of the upper Grande Ronde for three years, and the network already held Tam's nine-site packet and Helen Reuben's verified thermal record and topographic data going back to before Reyes was born. Four readings cross-referenced against all of that.
She could see the triangulation from here.
She got up and kept walking south.
The trail lost two thousand feet in four miles, and every five hundred of them the country changed underneath her. Subalpine gave way to open forest, grand fir and Douglas fir holding the north aspects, ponderosa and bare ground on the south. The south slopes were drier than she'd ever seen them. Bunchgrass had taken over from the shrubs that used to hold the soil, and in places the soil had gone out with the shrubs, so that the pale volcanic ash showed through with basalt rubble underneath it. A seasonal crossing was dry. The next one was dry. The third had a trickle moving through algae-slicked rock, and a woman was filling plastic jugs from it.
She looked up when Reyes came around the bend. Fifty or so, sun-darkened, wide hat, long sleeves in the heat. A handcart behind her on the trail held six more jugs, some full.
"That running all the way down?" Reyes said.
"To the culvert. Below that it goes under." The woman capped a jug and set it in the cart. "You're the one who walks the ridge."
"Sometimes."
"My husband says the spring above Benson Creek is putting out less this year."
"It is."
The woman looked at her. Reyes looked back. Neither of them was going to ask straight out. Reyes knew things about the water in these mountains that this woman needed, and the woman knew who'd been moving through this country lately, which Reyes needed, and it would go the way it always went — whoever had less to trade spent first.
"Saw two people headed up the North Fork road three days back," the woman said. "Young. Packs. One of them had a Yakama plate on the truck."
"Just the two?"
"Just the two. Didn't stop."
Reyes nodded. "The spring above Benson's been dropping four years running. It isn't coming back. There's a seep on the other side of the ridge — south-facing, below the old cat track. Small, but it's been steady."
The woman took that in without any expression at all and got both hands on the cart. "Happy Labor Day," she said, flat, the way you'd say happy birthday to somebody dead a long time.
"You too."
Reyes watched her push the cart down the trail. The jugs sloshed. The wheels caught on rock. She didn't look back.
Della laid the documents out across the table and stepped back to look at the gaps.
The table was old-growth Douglas fir, salvaged out of a building that had burned in the Toppenish fire in '59. The treaty administration had rebuilt in concrete and rammed earth, but they'd kept the table. Della used this room for meetings where she wanted the other party to feel the weight of what had stood here before them.
Two gaps. Between Helen Reuben's forty-five-year thermal record and Tam's nine-site assessment packet, a space where his fourteen cold-reach coordinates belonged. Between the packet and the satellite composites, another space where site-specific readings would have turned her argument into something firmer than inference.
She had enough to say the river system retained biological potential. She did not have enough to say that particular cold-water refugia persisted at particular places, which was the thing she actually needed — that opening the dams would reconnect habitat that still worked, not habitat that existed in the record and nowhere else.
Alahmoot's people would argue the thermal data showed a system in terminal decline. That the fish were functionally gone whatever happened to the dams. That generation was worth more than the memory of a run. Della needed the memory to be alive, and the man who could prove it was alive had decided the proof was the danger.
Cass knocked on the doorframe. Della's granddaughter was twenty-three and had her mother's mouth and Della's own hands and a way of standing in doorways that suggested she was still deciding whether to come in or use the exit behind her.
"Harlan's back from the Blues," Cass said. "Says Reyes is on her circuit. South Elkhorns. Two days from the Grande Ronde crossing, about."
"Did he talk to her?"
"He says she saw him and kept walking."
Della looked at the table. "Send him back up. Tell him I'm not asking for everything. I'm asking for enough."
Cass stayed where she was. "She's going to want to know what enough means."
"It means what it always means. Enough that the record doesn't say we gave it up."
Cass went. Della stood with the documents and the spaces between them. She picked up the Reuben record — a woman's handwritten field notes, digitized, verified, printed back onto paper because paper didn't ask for a password or a charged battery or a working uplink. Forty-five years of walking to the same nine points and writing down what the thermometer said. The simplest science there was. The kind you couldn't argue with. You could only decline to read it.
She set it down and went to find her coat. Nine days to the meeting, and she'd make the case with what she had, which was not enough, which was what she'd had every other time.
Harlan was at the Grande Ronde crossing two days later, which meant Della had turned him around the same day Cass reported him back. Della had never wasted time in the thirty years Reyes had known her.
He was sitting on a basalt ledge above the water with his boots off and his feet in the river, and the river was warmer than it had any business being in September. The Grande Ronde at this elevation used to run snowmelt-cold into October. It hadn't in years.
"She wants the thermal data," he said, not looking up.
"I know what she wants."
"Yeah. She said you'd know." He pulled one foot out and inspected the heel of it, which was raw. "Said to tell you she's not asking for everything. Just enough."
Reyes dropped her pack and sat down on the ledge next to him. The river was low, exposing cobble bars that had started growing grass. Willows had colonized the bared banks — not the native willows that used to line this stretch but the hybrid that had come up from lower elevations, tougher, less thirsty, with leaves that were wrong. Too narrow. Too gray. She'd watched them replace the natives over about a decade, and now they were just the willows, and there were maybe a dozen people left in the basin who knew they were wearing another species' name.
"Enough for what?"
"The compact meeting. She needs biological evidence that cold-water refugia are still out there. The dam assessment's authorized, but the case for opening's thin without site-specific numbers." He worked a sock over the raw heel. "Her words, not mine. I'm the mouth, I don't do the math."
"The case is thin because Tam won't release his coordinates. Tam won't release his coordinates because he's right not to."
"She figured you'd say something like that too." Harlan got the second boot on and started lacing. "She says if nobody puts evidence of life into the record, the record's going to say the system's dead. Absence of data reading as absence of fish."
"That's how it works."
"So she says you can fix it."
Reyes watched the river. A kingfisher was working the far bank, dropping off a dead branch into water too warm and too shallow for what it was hunting. It came up empty three times. On the fourth it got something small and silver and swallowed it up on the branch.
"If I give Della what she's asking for, it goes into the formal record," Reyes said. "The compact process is public. She knows that better than I do."
"She said a watershed-level statement would do it. No coordinates. Just — cold water persists in these named subbasins."
A watershed-level statement. Della's language, machined for the intake process. It would say: in the upper Grande Ronde subbasin, monitoring detected water temperatures consistent with cold-water refugia. It would not say where. It would not name the draw, or the spring, or the garden.
It would name the subbasin. The subbasin was small.
"Tell her I need to think about it."
"She said you'd say that too." Harlan stood up and tested the heel and winced. "She also said to tell you Alahmoot's already surveying the dam sites. He's got engineers at Ice Harbor. Assessment comes back without biological evidence for opening, the default is repair. Power wins by not showing up."
Reyes had known that since the vote, when Della and Alahmoot authorized the assessment together and everybody in the room understood that the assessment was where the fight would be. Whoever controlled the evidence controlled the outcome. Della needed proof of life. Alahmoot needed proof of death, or close enough. And the river, which had no position on any of it, kept getting warmer.
"Nine days," she said.
"Nine days." He shouldered his pack. "I'm camping at the old trailhead tonight, heading back at first light. Anything you want carried, I'll be there till dawn."
He went off downstream, favoring the foot. Reyes stayed on the ledge. The kingfisher dove again and missed.
She found Naya the next morning at the Benson Creek waypoint, exactly where the circuit schedule Reyes had taught her said she'd be. The younger woman was sitting cross-legged on a flat rock annotating vegetation transects on her tablet, and she looked up when Reyes came through the trees and smiled, and the smile was uncomplicated, and Reyes felt something turn over behind her ribs that she didn't put a name to.
"You pushed thermal data through my Elkhorn node."
The smile went somewhere more careful. "Four readings. Coordinates stripped. No watershed tags, no aspect, no access notes. Temperatures, elevations, substrate types."
"Through the church mesh."
"It's the most distributed thing we have. If something happens to us — to you, to me, to Tam — those readings still exist. Forty copies across six nodes. They can't be lost."
"They can be cross-referenced."
"Against what? Four numbers with no locations on them?"
Reyes sat down across from her. The rock was warm through her pants. Below them Benson Creek was mostly a memory of water — dry cobble, cracked mud, a couple of pools holding the last of the spring pulse. The seep she'd described to the woman with the cart was visible on the opposite slope, a dark line of vegetation running across brown ground where subsurface water came up. Small. Steady. Enough to keep one household alive and nobody at all if it ever got written into a supply inventory.
"Against everything Oliver already has," Reyes said. "Three years of spatial modeling. Tam's nine sites. Reuben's record. Topography, satellite composites, gauge archives going back a century. You gave him four points and he's got the rest of the constellation. How long do you think that takes him?"
Naya closed the tablet. "Oliver isn't trying to find the sites. He's trying to understand the system."
"Oliver's trying to understand the system the way a monk tries to understand God. All devotion and no idea what gets done with the understanding once he's got it."
"That's not fair to him."
"It's not about fair. It's about what happens to information after it's in a network that includes people who aren't Oliver." Reyes looked at the dry creek, the seep-line, the smoke that had thickened over the valley since yesterday. "You made a decision about information that wasn't yours to make."
"It wasn't yours either."
Reyes let that sit, because it was true in the specific way a person can be right about the principle and wrong about the application. The data belonged to the sites, if it belonged to anybody. Tam collected it. Reyes helped him plan the survey. Fern walked them to the spring. Reuben spent forty-five years building the baseline that made any of the numbers mean something. Reyes's claim on it was no better than Naya's.
What Reyes had that Naya didn't was twenty years of watching what happened to a place after somebody gave it a number. She'd watched two of them go that way herself — a seep on the Umatilla side that got into a supply inventory and had a fitting on it within a season, and the Camas Creek meadow, which was now a gravel pit.
"I'm not angry," Reyes said. "I'm scared."
"Of what?"
"That you're right and I'm right and there's no safe way to hold it. Kept or handed over."
Naya studied her. "Della's asking for it."
"Harlan found me at the crossing yesterday." Reyes paused. "How did Harlan know the readings existed?"
"I didn't tell him."
"Somebody did. He came up the trail already knowing there was new data."
Which meant it was moving. Naya's upload into the mesh, Harlan's knowledge of it, Della's awareness that something existed she hadn't been given. The convergence Reyes had warned Tam about was happening on schedule, and the schedule was faster than she'd estimated, the way it always was.
"Here's the part you need to think through," Reyes said. "A watershed-level statement — cold-water refugia persist in the upper Grande Ronde subbasin — goes into a public record that Alahmoot's engineers read, and Boone's people read, and the sovereign's analysts read. The subbasin's small. The count of perennial springs in it is smaller. The count of perennial springs coming out under fifteen degrees in September is smaller than that. Nobody needs coordinates. They need a temperature, a subbasin name, and an afternoon with a topographic model."
Naya was quiet. This time the quiet had weight in it. She was doing the arithmetic.
"So we can't give Della anything."
"Go back to your transects," Reyes said, and stood. "I'll think tonight."
She camped on a bench above the river, a spot she'd used for years. Naya was two miles north at the waypoint. Harlan was gone, walking back to Toppenish carrying nothing. The smoke had settled into the valley and the stars came through it dim and orange-edged, and the air tasted like August though it was September, because fire season had stopped keeping to the calendar around the same time the calendar stopped keeping to the seasons.
She ate cold — sorghum cake and dried apple, sitting on her pack — because the smoke had eaten most of the day's charge and she wasn't spending what was left on a stove. The panel had taken in less than half of what it should have. She unfolded the tablet and checked the state-of-charge and decided she had about ninety minutes of screen if she kept the brightness down.
The counter-map came up in the dark.
Eleven years of it. Her own observations, Tam's surveys, things traded with people like the woman with the cart, satellite pulls from the narrow windows when she'd had uplink, old Forest Service sheets she'd photographed off paper in abandoned ranger stations and rectified by hand. The most complete spatial record of water in the interior basin that existed outside the treaty archive, and complete precisely because it was nobody's — people told her things they would never tell an institution, and she wrote down things institutions had no line item for.
Fern's draw was on it. A point, good to three meters, in the upper Grande Ronde: the spring-fed cool refuge where Fern grew amaranth and sorghum and medicinal herbs on ground the risk models had zeroed out. Tam had read the spring at 14.2 degrees six months ago and Reyes had hung the number on the point. The point also carried elevation, aspect, substrate, vegetation notes, access description, timestamp. Eleven fields. A complete portrait of a place that was still there because the portrait had never been shown to anybody in a position to act on it.
Give Della the point and Della had her proof of life. A verified, located, specific cold-water refugium, and a real argument that opening the dams would reconnect something that still worked.
Withhold it and the assessment went forward without biological evidence, and the default was repair, and Alahmoot's engineers got their generators, and the record said by omission what it would then keep saying: dead, no further inquiry warranted.
Reyes zoomed in until the draw filled the screen in false color. Spring source, the channel it fed, the little flat where Fern had built her beds, the slope above where juniper and bitterbrush ran out into bunchgrass and bare dirt. Three meters of precision. Close enough to walk a stranger from the trailhead twelve miles out straight to the water.
She opened the editing tools and started drawing.
What she built took forty minutes and most of what she had left on the battery. A polygon, irregular, following the drainage divides: everything in the upper Grande Ronde above 3,800 feet, roughly forty square miles. It took in Fern's draw. It also took in nineteen other draws, seven seasonal creeks, three abandoned homesteads, a decommissioned guard station, and a few hundred acres nobody had walked in a decade. She set the declared scale, entered the uncertainty, wrote the attribute string herself so no one could claim she'd been vague by accident.
Somewhere in this area, a cold-water feature persists. Below 15 degrees. Late summer. Spring-fed.
True at the scale declared. It would hold up under review. It would carry Della's argument. It would not carry anyone to Fern's door.
That part was the easy part.
Reyes selected the original point and opened the deletion dialogue.
A protected layer could be unprotected. A device could be taken, or lost, or inherited by somebody who didn't know what the points meant and passed them to somebody who did. The only record that couldn't come off a device was one that wasn't on it.
The tablet asked her to confirm. She confirmed. It asked again, because she'd set the primary layer to double-prompt years ago, a safeguard she'd built against a night exactly like this one, when she might be moving out of fear instead of judgment and would need a breath.
She took the breath. The smoke shifted; somewhere south of her the fire was still running, and she'd find out in the morning what kind of silence the mesh was keeping about it.
She confirmed.
The point was gone. The polygon stayed. Eleven fields collapsed into four, and the line connecting a temperature to a particular spring in a particular draw where a woman grew food on ground the world had written off now existed in three heads. Hers. Tam's. Fern's.
She saved the file and shut the tablet and folded the panel flat so it would catch whatever the morning gave her. Then she picked up her bottle and finished it and sat working out the route to the nearest fill point, because the next thing was always water.
