The delivery lorry jolted over the gravel drive and its tailgate slammed down hard, banging twice against the hinges. A drum of echo-sounder paper, big as a barrel, tipped off the edge and hit the grass with a thud. It began to roll, unspooling a long white ribbon behind it as it gathered speed down the sloping lawn toward the cliff edge above the Hudson. Marie dropped the box she was carrying and ran, shouting for help. Howard sprinted from the porch, pencils jangling on his belt, and Rosa scrambled out from behind the hedge, braids flying. The drum bounced over a molehill and veered faster toward the drop. Howard grabbed the garden wheelbarrow and flipped it upside down into the drum's path. Marie threw herself against the ribbon of paper, hauling it back with both arms, while Rosa dove to pin the loose end under her sneakers. The drum slammed into the wheelbarrow and stopped dead, rocking, inches from the edge where the land fell away to the river far below.

The stone stairs down to the coal cellar were steep and narrow, barely wider than a crate, and the three of them hauled the wooden boxes down one careful step at a time. Howard went first, braced backward with the crate's weight pressing into his chest, while Marie steadied it from above and Rosa scurried ahead to clear coal lumps from the path. On the fifth crate, one bottom board gave a sharp crack and split clean through. Thousands of thin paper sounding slips burst loose, snowing down in a white flurry toward the black coal dust below. Howard lunged sideways, roaring a warning. Marie dropped her end and grabbed at falling handfuls. Rosa didn't hesitate — she yanked a folded bedsheet from the laundry pile, snapped it open and stretched it taut between her small fists, running beneath the fluttering storm to catch the last drifting slips before they touched the grime. Papers piled soft and white in the sheet's hollow, saved just inches above the furnace's sooty floor.

The rope creaked as they hauled the old cellar door up the narrow stairwell, hand over hand, its weight banging against the walls. "Pull, don't drop it!" Marie called, bracing her shoulder under the door's edge. Howard climbed above, hauling the rope taut around the newel post, muscles straining under his rolled sleeves. Rosa scrambled ahead, clearing boxes from the attic floor so the door could clear the top step. Together they heaved it flat across four filing cabinets, the door settling with a hollow thud to make a drafting table twenty feet long. Marie unrolled the first long sheet of sounding paper across it, and the draft from the dormer windows caught it instantly, lifting a corner like a sail. Rosa slammed her tin pail down on one end, Howard dropped a flatiron on the other, and Marie scattered pebbles along the middle to pin it flat. The three of them stood back, breathing hard, grinning at the long white sheet stretched tight under the slanted beams.

They carried the finished profile out onto the pier like something sacred, and rolled it flat along the planks, foot by foot, until it stretched longer than three fishing boats tied end to end. Howard knelt and smoothed each seam with his palm, counting out loud. Rosa trotted along the far edge, pressing down corners with her sneakers. Then the river wind swung round off the Tappan Zee, got under the paper like a sail filling, and the whole twenty feet of it lifted with a crack and sailed toward the open water. "Grab it!" Marie shouted, already diving. All three of them hit the planks together, flattening the paper under elbows and knees before it could slide off the pier's edge. Howard hauled the mooring rope across one end and knotted it fast. Rosa jammed her seagull pail down on a flapping corner. Marie dragged two loose stones from the shingle and dropped them on the last edge, breathing hard, grinning up at the sky.

The crane groaned on Pier 2, its long steel arm swinging a wooden crate taller than Rosa's shoulders out from Vema's deck over the gap of oily green water between ship and quay. Howard saw it tilt toward the piling and raced along the planks, waving an arm in warning. Bruce was already moving, boots pounding the boards, boat hook raised high. He lunged and hooked the crate's rope sling, hauling it sideways through the air, muscles straining against its swing. Marie grabbed his coat from behind to steady him as he leaned far out over the water, calling for him to ease it down slowly. Rosa darted underneath, small arms stretched up, both hands flat against the crate's rough side, pushing and guiding as the crane's chain rattled it lower. The crate thudded onto the quay, rocking, and Rosa threw her whole weight against it until it settled flat and still. Everyone exhaled at once, grinning, the Manhattan skyline glinting far across the water behind them.

Six long profiles lay side by side along the potting benches, each one unrolled from end to end like a fallen ribbon. Marie walked down the row with her dividers swinging, comparing notch to notch, and her breath caught. "Howard — look. The same V. Every single one." Howard bent close, grease pencils jangling, and tapped each dip in turn, counting aloud. Bruce leaned over the fifth sheet, stopwatch chain scraping the bench edge, and let out a whoop that startled his own elbow into the watering can. It toppled, water sheeting fast down the slatted wood toward the papers. "Grab them!" Marie shouted, already snatching the nearest sheet overhead. Rosa dropped her seagull pail and flung herself the length of the bench, scooping two profiles up before the water reached them. Howard hauled the far end clear with both arms, holding it high against his chest. Bruce slammed the can upright, stemming the flow, breathing hard, grinning despite himself at the soaked bench and the six dry, rescued sheets held safe above their heads.

Bruce frowned at the long sheet pinned across his cluttered desk, hip-high under its stacks of charts, and dragged a fat rubber eraser across the inked rift valley. 'It's too neat,' he muttered, scrubbing harder, 'the ocean floor can't split open like a seam.' The damp paper bunched, buckled, and tore clean through with a dry rip that made everyone jump. Rosa dropped to her knees beneath the desk, scrambling to catch the sagging corner before it touched the floor, then pressed a strip of gummed tape from behind, smoothing it flat with both thumbs. Howard steadied the far edge with both hands so the whole map wouldn't sag further, his pencils jangling as he leaned in. Marie said nothing. She dipped her pen, waited for the tape to set, and quietly inked the valley back in, line by patient line, exactly where it had been. Bruce watched the crack reappear under her hand and set the eraser down slowly, as if it had tried to argue with the sea and lost.

The vault was dim and cold, concrete walls pressing close around the turning drums of smoked paper. Howard dragged the stepladder, taller than himself, across the floor and set its feet with a clank beside Marie's wall-sized map. He climbed, the ring of coloured pencils jangling at his belt, a long curl of tracing paper rolled under one arm. Bruce steadied the ladder's legs with both boots planted wide, calling up corrections, while Rosa scrambled onto an upturned crate to hold the paper's trailing edge out of the dust. Howard pressed two pins into the top corners, then let the long sheet drop. It fell flat against the map with a soft slap. For a breath nobody moved. Then Marie leaned close, tracing the valley line with one finger, and gasped — every single inked earthquake dot sat inside her drawn rift, not one astray. Rosa whooped and nearly toppled off the crate; Bruce caught her elbow and hauled her steady.

The rolled map rode on their shoulders like a felled log, heavy and awkward, bumping the doorframe of the lecture theatre as they hauled it down the steps. Howard took the front end, bracing it against his chest, while Marie and Rosa gripped the back, grunting with each step down the tiered aisle. At the chalkboard they dropped it flat with a thud, and Bruce grabbed the loose end and ran backward, unrolling it foot by foot all the way to the back doors, nearly tripping over an upturned seat. Scientists scrambled up onto the theatre benches to see over each other's shoulders, pointing down at the long dark crack splitting the painted Atlantic in two. Rosa knelt and smoothed a stubborn curl flat with both palms. Howard pinned the far corner down with a heavy brass lectern bell. Someone at the back shouted a question, and Marie straightened, dusting chalk from her hands, ready to answer every one of them.

The black lava cliffs rose higher than any house on either side, and between them the ground itself lay split open, a crack wide enough to swallow a wheelbarrow. Howard hauled the big printed map from its cardboard tube and shook it open, and Rosa — taller now, her braids nearly level with his shoulder — grabbed two corners and dragged them flat across a slab of rock as broad as a kitchen table. Bruce dropped a stone on each corner, thump, thump, thump, thump, pinning the paper against the wind off the waterfall. Marie stood at the lip of the real rift, the dividers swinging loose on their cord, and planted one shoe on the near side, one on the far side, straddling the crack with her arms out for balance. Below them the silver lake stretched to the hills. Nobody spoke for a moment, just the roar of falling water and the paper snapping at its stone corners.
