The earth split open and the world around Hetty erupted in a roaring inferno of purple-red fire and ear-shattering sound. The rolling concussion swept Hetty from her feet and tumbled her into a drywash gully at the base of the hill. The gully saved her life as the sky-splitting shock wave rolled over her. Stunned and deafened, she flattened herself under a slight overhang.
The rolling blast rocked ranches and towns for more than one hundred miles and the ground wave triggered the seismographs at the University of California nearly two hundred miles away and at UCLA, four hundred miles distant. Tracking and testing instruments went wild along the entire length of the AEC atomic test grounds, a mere sixty miles south of the smoking, gaping hole that marked the end of the Circle T pickup truck.
In a direct line, the ranch house was about eight miles from the explosion.
Johnny was lounging in Hetty's favorite rocking chair on the wide back verandah, lighting a cigarette and Barney was perched on the porch railing when the sky was blotted out by the dazzling violet light of the blast. They were blinking in frozen amazement when the shock wave smashed into the ranch, flattening the flimsier buildings and buckling the side and roof of the steel-braced barn. Every window on the place blew out in a storm of deadly glass shards. The rolling ground wave in the wake of the shock blast, rocked and bounced the solid, timber and adobe main house.
The concussion hit Johnny like a fist, pinwheeling him backwards in the rocker against the wall of the house. It caught Barney like a sack of sodden rags and flung him atop the dazed and semiconscious younger man.
The first frightened screams of the horses in the barns and corrals were mingling with the bawling of the heifers in the calf pens when the sound of the explosion caught up with the devastation of the shock and ground waves.
Like the reverberation of a thousand massed cannon firing at once, the soul-searing sound rumbled out of the desert and boiled with almost tangible density into the shattered ranch yard. It flattened the feebly-stirring men on the porch and then thundered on in a tidal wave of noise.
Barney moaned and rolled off the tangle of porch rocker and stunned youth beneath him. Johnny lay dazed another second or two and then began struggling to his feet.
