The Rescue Beacon Is Broadcasting From Under Three Miles of Granite

That code belonged to the beacon in Captain Mara Venn's hand.

She held it beside the receiver so we could compare transmissions. Her unit was switched off. The duplicate signal continued from below us, identical down to the factory serial number and the small timing fault that made every fifth pulse late.

I coordinated radios for the county mountain-rescue team. My name is Elias Wren. In twelve years, I had tracked avalanche transponders beneath snow, emergency locators down ravines, and one satellite messenger carried twenty miles by a curious bear.

I had never tracked a signal through miles of rock.

The voice channel opened by itself.

Mara's voice said, 'Base, this is Alder One. Three injured. Request extraction.'

She was standing next to me, not touching her radio.

The transmission repeated. This time her voice added, 'Elias, confirm you copy.'

Mara covered my microphone before I answered.

Our oldest volunteer, Sam Orra, went pale. He pulled a folded card from his jacket and handed it to us. It came from a ranger manual printed in 1964.

Its heading read SUBSURFACE DISTRESS SIGNALS.

DO NOT CONFIRM YOUR NAME TO A BEACON BELOW BEDROCK.

DO NOT ATTACH A RESCUE LINE UNTIL THE VICTIM CASTS A SHADOW.

IF THE SIGNAL RISES FASTER THAN YOU CLIMB, ABANDON ALL EQUIPMENT THAT KNOWS YOUR CALL SIGN.

Sam said his father helped write the card after three rescuers disappeared on Mount Alder. Their team followed whistles into a crevice after a landslide. Only one man returned. He carried four rescue ropes clipped to his harness and insisted they were attached to survivors beneath the rock.

When the ropes were pulled, they ended in knots shaped like human hands.

The county removed the page from later manuals.

At 6:32, a rockfall opened a crack fifty yards above our command post.

Cold air blew from it, smelling of old wool and battery acid. The underground signal jumped upward two thousand feet and stopped directly behind the opening.

The voice channel played a chorus of emergency calls.

Some were recent. Others used radio procedures abandoned decades ago. Men and women reported broken legs, lost partners, whiteout conditions, and falls that never ended. Every call concluded with the same sentence:

'Tell us who is coming.'

Mara selected a three-person entry team: herself, Sam, and me. We carried a rope, medical kit, gas meter, and one unregistered analog radio with no stored call signs. We left every personal beacon outside.

The crack should have ended after ten feet. Instead, it widened into a descending passage polished smooth by hands.

Chalk arrows covered the walls. Some matched rescue-team markings from the 1960s. Others were fresh. One was drawn in the orange chalk Mara carried in her pocket.

She checked. Her chalk stick was unused.

The arrow pointed down.

We followed the signal for forty minutes. Our altimeter said we had descended three hundred feet. The receiver said the beacon remained three miles below, still climbing twenty feet per minute.

Then we passed ourselves.

A side chamber held three packs arranged against the wall. Mine was open. Mara's orange chalk lay beside it, worn to a nub. Sam's thermos was still warm. On the ground, a rescue log in my handwriting recorded our names and a time six hours ahead.

The final entry said: DO NOT LET SAM CLIP THE LINE.

We left the chamber without taking anything.

The underground voice began using Sam's father's call sign.

'Orra Two, I found them,' it said. 'Bring the line.'

Sam kept walking, but tears ran down his face.

At 7:41, the passage opened into snowfall.

White flakes rose from a dark abyss, falling upward past us and vanishing into stone. Headlamps moved far below, hundreds of them, climbing switchbacks cut into empty air. We heard crampons on rock where no ledge existed.

The beacon signal came from the nearest light.

A climber emerged from the dark.

He wore layers of rescue clothing from different decades: canvas trousers, modern shell jacket, leather boots, plastic helmet. Patches on his chest carried the names of missing rescuers. His face changed whenever our headlamps moved—young woman, bearded man, frostbitten child, Sam's father.

He cast no shadow.

A beacon hung at his throat. It was Mara's exact unit, aged and scratched.

'Three injured,' he said in her voice. 'Request extraction.'

Behind him, shapes climbed through the upward snow. Each had too many arms stretched toward our rope.

Mara asked for the names of the injured.

The climber smiled with my mouth. 'Whoever comes to help.'

Sam stepped forward.

His father appeared on the climber's face. 'Son, clip me in.'

I grabbed Sam's harness. He struck me hard enough to split my lip, pulled the rescue line free, and clipped a carabiner to the stranger's chest loop.

The second rule had been broken.

The stranger cast Sam's shadow.

It spread behind him across the cavern wall, though no light stood in front of them. Sam's body became transparent. I saw ropes running through him where veins should have been, all descending into the abyss.

The underground climbers pulled.

Sam vanished down his own shadow. The stranger rose into his place wearing Sam's face and holding the rescue line.

Our analog radio spoke with Sam's voice. 'Victim secured. Begin extraction.'

The line jerked upward toward the surface.

Something above had begun hauling it in.

Mara cut the rope. The severed end did not fall. It withdrew into the ceiling, sliding through granite without resistance. The stranger screamed through every missing person's voice and climbed after it on empty air.

The beacon had learned the last step of rescue: once clipped to a line, the victim is brought home.

We ran uphill.

The passage contracted behind us. Rock closed around the stranger but did not slow it. The receiver in my pack showed the signal rising faster now—five hundred feet per minute, then a thousand.

I threw the receiver away. The third rule said to abandon equipment that knew our call signs.

It landed screen-up. My name appeared where the depth reading had been.

ELIAS — EXTRACTION PENDING.

Mara discarded her radio and helmet. I threw away my medical tag, GPS, and phone. Each object hit the ground and began transmitting a distress pulse.

The mountain filled with beacons.

They blinked from cracks, packs, old bones, and rusted climbing hardware. Thousands of red lights woke beneath the rock. All of them spoke our names.

We reached the chamber with our duplicate packs. This time Sam's was gone. The future rescue log had changed.

Two names remained at the top: Mara Venn and Elias Wren.

The final entry now read: ONE OF US OPENS THE CRACK.

Behind us, Sam called for help.

Mara stopped. I shouted that it was not him.

'I know,' she said. 'But it has his shadow.'

The passage ahead had sealed to a narrow seam. Daylight showed through the other side. There was room for one person at a time.

Mara pushed me through.

As I crawled, she remained behind and answered the voice using her full call sign. Every underground beacon turned toward her. The mountain shuddered. The crack opened long enough for me to fall into daylight, then closed with Mara inside.

The signal stopped.

Search teams found no entrance, despite fifty witnesses seeing us enter. County records said our three-person team had consisted only of me and Sam. Mara's name vanished from rosters, photographs, and payroll. Sam was listed as missing on Mount Alder in 1964, twenty-two years before he was born.

I resigned from rescue work.

For months, I avoided radios and never spoke my old call sign. The scar on my lip healed. Mount Alder remained quiet.

Yesterday, a package arrived without postage. Inside was Mara's beacon, clean and new.

Its battery was removed.

At 6:14 this morning, it began pulsing on my kitchen table.

The display says the signal is six feet below me and rising.

Mara's voice keeps asking who is coming to help.
