The Denver Post:
The night sky turned to daylight briefly as an epic boom echoed throughout the valley in Steamboat Springs Saturday night. The world’s largest single firework had just exploded.
At 7:56 p.m., fireworks expert Tim Borden successfully captured the world record for the largest single firework when the 2,797-pound behemoth illuminated the crowd during the Night Extravaganza at the annual Steamboat Springs Winter Carnival.
The 62-inch shell was launched from a 26-foot long mortar from atop Howelsen Hill, reaching nearly a mile in the air when it detonated, putting on quite the show.
That was one hell of a blast. I hope everyone in the area knew about it because that would scare the bejesus out of you if you were just out walking the dog.
