Chapter 74 - The Siphon of the Ancients
The kitchen windows rattled violently in their wooden frames. The water in the copper kettle on the stove began to swirl in a tight, counterclockwise vortex, even though the burner beneath it was cold.
"Sam, look out the window," Dad whispered, standing by the lace curtains.
I stepped beside him. Down across the meadow, where the high-pressure water mains from Vance’s mining project had been capped three days ago, the earth was bulging. The pasture grass seemed to stretch like green rubber over a rising dome of pressure. From the creek bed, the clear mountain water had stopped flowing entirely; it was receding backward, running upstream, being drawn down toward the base of the limestone bluffs into a sinkhole that had opened like a yawning black maw in the gravel bar.
The entire hydrological balance of Blackwood County was collapsing inward, centering directly beneath the foundation of our house.
"The county records weren't just forged to steal the farm," I said, the pieces snapping together with terrifying clarity. "Julian Vance’s grandfather knew about the siphon. The 1968 Deep Well Project wasn't an environmental study or a government silo. They were trying to bypass the lock. They were drilling right into the chamber roof to tap the pressurized brine."
"And if they tapped it?" Dad asked.
"The whole valley drops," I said. "Three hundred feet of limestone hollowed out by an underground lake under ten thousand pounds of pressure. If the siphon blows its seal, the sinkhole will swallow everything from here to the county courthouse."
The telephone on the kitchen wall—dead since the storm two nights ago—suddenly let out a sharp, ear-piercing ring.
Dad and I both froze.
The phone rang again. *RRRR-ING.*
I crossed the room, lifted the heavy black Bakelite receiver, and pressed it to my ear.
"Miller," a voice crackled through a blizzard of static. It wasn't Julian Vance. It was the smooth, clipped tone of the Langley surveyor who had fled the ridge during the subterranean breach. "Listen to me very carefully. You’ve triggered the primary pressure differential at Site Zero. The automated fail-safes from the '68 installation have just engaged. A demolition charge is wired to the North Ridge aquifer head. In forty minutes, the bypass will be blown to relieve the pressure on the valley floor. If that happens, the salt brine will poison the entire Virginia water table for fifty miles."

"How do we stop it?" I demanded.
"You don't stop it from up there," the voice replied, devoid of emotion. "You have Silas Miller’s compass and the key. The true intake isn't in our tunnels. It's beneath your cellar floor. You have to seat the key into the granite core before the fail-safe timer runs to zero. If you don't, there won't be a Blackwood Creek left on the map."
