New York City's long streets and avenues cut like deep, angular gouges through the high towers of Manhattan. They lie on a grid. The streets run more or less from east to west and the avenues north to south.
That means that most of the year, the sun rises and sets out of sight of most street-level city dwellers, hidden behind row after row of buildings.
But twice a year something almost magical happens: The path of the sun in the moments before it sets aligns perfectly with the east-west lines of the city's grid. Fiery evening sunlight creeps around the edge of the skyline, then rushes down the length of those long streets, bathing them in a hot, orange glow.
The effect is briefly stunning. And it mirrors at massive scale the one visible twice yearly at the ancient Stonehenge monument, giving it its name. New Yorkers rush the centers of the island's busiest streets to see it, crowding sidewalks and clogging traffic.
