Skeletons in the Rock

Could three inches of tempered tool steel drop eight hundred pounds of thrashing muscle before a wild boar’s tusks sheared the last two copper ignition leads?

Penn Stafford did not wait for the dust from the splintered parapet to clear. He drove his weight forward across the smoking firing bench, boots skidding on loose shale, his left hand locking onto the stiff, bristle-matted ridge between the beast’s ears. The animal was blind from the magnesium quill, shrieking in high, wet spasms as it threw its bulk against the rock, but its curved lower tusk had already hooked the cedar housing of the primary detonator. Wood groaned. Inside the casing, the brass balance tipped three degrees toward the battery contacts. If the balance touched early, thirty tons of charged sandstone would blow before Penn could seat the delay collar, taking the firing ledge, Garth, and Penn himself down into the canyon draw.

Penn did not swing the knapping mallet. A wild strike against the skull plate would only bounce off the heavy bone dome and shatter the cedar box beneath. Instead, he positioned the chisel point of his steel punch directly behind the boar’s left ear, finding the narrow soft seam where the cervical spine met the skull base.

He struck once. The mallet met the hardened steel head with a sharp, dry crack.

The boar stiffened instantly, all four legs snapping rigid. Its breath left its snout in a long, rattling hiss. Penn threw his shoulder into the beast’s flank, levering the dead mass sideways. The carcass rolled over the edge with a dull scrape, tumbling three hundred feet into the ravine where it hit the scree slope with a distant, muffled thud.

"Garth," Penn said, his voice level despite the chemical stink burning his throat. "Ignition harness. Now."

Garth Lin pulled himself out of the gnarled juniper roots, spitting red sandstone dust. His fingers were scraped raw and his skinning knife had vanished down a hairline fissure in the rock, but his eyes were sharp. He dropped to his knees beside the firing bench, inspecting the mangled cedar casing.

"The tusk took the left terminal," Garth muttered, wiping grit from his brow. "Sheared the braided copper clean off the binding post. An eight-hundred-pound tusker trying to eat our battery was bad enough, but Carver’s hound scrambling up sheer quartz like a bloated iron tick is just insulting the whole trade of quarrying."

"He is forty feet from the lip," Penn said, not looking up. He reached into his tin maintenance kit, pulling two brass fuse-pins and a six-inch length of uninsulated lead wire. His hands moved with clean, mechanical economy. "Carver knows the arch went down. He knows his wagons are bottled in the wash. He is not climbing to negotiate."

"Then we blow the master shelf now," Garth said, reaching for the secondary friction cord.

"No," Penn said, catching Garth’s wrist with grease-stained fingers. "If we trip the charges without the delay balance, the shockwave propagates southward instead of shearing the face. It will drop thirty thousand tons of overburden directly into the canyon floor. It will crush the freight wagons, the draft teams, and sixty people who have no idea what they are driving over."

"Penn, they’re caravaners," Garth snapped, though his hand stayed frozen on the cord. "They pay the toll. They grease the garrison captain’s palm every three months to keep the road open."

"They are ignorant," Penn said. He stripped a quarter-inch of braided wire with his thumbnail and drove a brass pin through the copper core, jamming it directly into the antimony cell’s primary contact plate. A blue spark bit the edge of his thumb, the sharp smell of ozone joining the alkaline haze. "Ignorance is not an execution order. The highway foundation comes down. The bedrock bares its teeth. That is the work. Nothing more."

Below them, thirty feet down the vertical quartz chimney, a heavy iron ring clinked against stone.

It was a wet, rhythmic sound, accompanied by the low, resonant scraping of heavy metal claws finding purchase in narrow granite seams. The Scale-Hound worked the rock like an oversized wedge, its broad, scale-plated shoulders rolling with hydraulic force as it jammed its forelimbs into vertical cracks and levered its four-hundred-pound frame upward. Behind it, tethered by a thick hemp line looped through a steel climbing piton, Hayes Carver climbed with deliberate, rhythmic speed, his short-hafted billhook gripped between his teeth.

"Ten seconds," Garth whispered, leaning over the ledge with a heavy pry-bar in his hands. "Penn, the beast is clearing the second shelf. Its snout is ten feet down."

"Hold the bar," Penn commanded. He seated the second brass pin, twisting the lead wire until the antimony-vitriol bridge clicked into alignment. The small brass indicator needle on the cedar box jumped, quivering in the green quadrant. The circuit was live.

Two primed chemical drop-charges sat fifty yards north along the canyon rim, anchored deep inside the natural shear fault Penn had surveyed three days ago. When the antimony triggered, the vitriol would boil through the calcified lime anchors, dissolving the cohesion of the sandstone cliff in three-tenths of a second. The master shelf would drop straight down, shearing the road’s protective resonance layer like a knife through soft tallow.

The air above the rim suddenly grew hot.

A thick, yellowish vapor spilled over the rock edge, smelling of charred mutton fat and boiling copper. A massive, wedge-shaped head crested the canyon lip.

Brisket’s heavy, plated brow emerged into the dawn light. The hound’s jaw was flecked with bright, metallic foam, its yellow slit-pupils locking onto the cedar detonator box with manic, chemical focus. The refined copper binding posts and antimony ampoules radiated heat and electrical charge across the dry sandstone, drawing the beast straight toward the live metal.

The hound let out a low, vibrating growl that made the gravel dance around Penn’s boots. With a sudden, terrifying heave of its corded hindquarters, the beast scrambled over the lip, its iron-shod claws gouging deep trenches into the soft upper rock course.

"Get back!" Garth yelled, swinging the pry-bar with both arms.

The heavy ash-and-iron bar slammed across the beast’s left shoulder plate with a ringing clang. The impact would have broken the leg of a draft mule, but against Brisket’s thick, layered scales, the bar merely bounced, sending a jolt of recoil through Garth’s elbows that nearly tore the tool from his grip. The hound did not even flinch. It snapped sideways, its powerful jaws catching the iron tip of the pry-bar and shearing two inches of forged metal off with a single, sickening crunch.

"Down!" a voice roared from the chimney.

Hayes Carver cleared the rim in a single explosive lunge, his boot catching the lip and vaulting him onto the shelf. His canvas coat was ripped across the shoulder, and the linen dressing on his right forearm was stained dark with sweat and old vitriol burns, but the short-hafted billhook in his hand was balanced, low and ready.

Carver’s gray eyes locked onto Penn across the ten feet of flat sandstone that separated them.

"Step away from the box, Stafford," Carver said. His voice was raspy, stripped raw by the climb, but utterly steady. "You drop that shelf, and you bury sixty teamsters who never did you harm."

"Look at the foundation beneath your wheels, Carver," Penn said, his thumb resting lightly on the friction release lever of the cedar box. He did not raise a weapon. He did not back up. "You spent five years hauling copper across this border. Did you ever ask why the wild never crosses the ditch? Did you ever ask what they mixed with the lime to keep the stones humming?"

"I keep my freight moving and my beast fed," Carver said, taking half a step to his left, positioning himself between Penn and the chimney. "That is the contract."

"Then your contract is built on a slaughterhouse," Penn said coldly.

Brisket took another step forward, sniffing the air. The scent of raw copper wire inside the detonator was overwhelming. The hound lowered its head, muscles coiling along its spine, its throat glowing with a faint, cherry-red heat as its internal furnace primed for an extraction.

"Brisket, heel!" Carver barked.

The hound hesitated for a fraction of a second, its heavy head snapping between Carver’s command and the scent of the raw copper wire. But the draw of the live battery was too close. The beast surged forward, its massive skull lunging directly for the firing bench.

"Penn, pull it!" Garth screamed, scrambling backward toward the juniper scrub.

Penn did not hesitate. He calculated the vectors in an instant: if Brisket swallowed the battery whole, the internal acid would trigger the antimony ampoules inside the beast’s stomach, detonating the charges out of phase and blowing the entire rim into the chimney.

Penn slammed the friction plunger home with the heel of his hand.
