Colo. lab gets record hailstone

Tuesday, August 3, 2010

BOULDER, Colo. -- North America's heaviest hailstone ever might also be its most-traveled.

A 1-pound, 15-ounce hailstone that fell in Vivian, S.D., on July 23 has been taken to the National Center for Atmospheric Research in Boulder, Colo., about 370 miles away.

Charles Knight, a scientist at the center, plans to cast plaster replicas for researchers, a South Dakota museum and Leslie Scott, the ranch hand who found it.

Knight said he'll then cut it in two and photograph its internal rings.

The hailstone is being stored in a freezer.

Federal climate officials have confirmed the hailstone is the heaviest ever recorded on the continent.
