Nevada Test Site (NTS) Pictures
As the first faint streaks of dawn poked over the distant hills the blast came.
A vivid flash of light pierced the desert darkness and lighted up the entire
countryside. It lasted but a moment or two then was gone. All eyes turned
toward the spot where the bomb had exploded. They saw a big ball of furiously
churning fire, smoke, sand and debris rapidly rising from the ground in huge,
rolling waves. The afterglow remained for several minutes while the mushroom
cloud continued to rise then drift away and apart. Then sun was still below the
horizon but daylight was coming fast. Broad streaks of sunlight slanted over
the mountain tops like ghostly fingers clawing at the heavens. Rumbling of the
shock wave continued for nearly five minutes, bouncing back and forth from
one mountain wall to another.
