Hail storms
Hail is precipitation in the form of balls or irregular lumps of ice, called hailstones,
produced in a thundercloud. When the ice becomes too heavy, it falls down from the
thundercloud. A hail storm may last for only ten minutes, but it can destroy crops
worth millions of dollars. Planes caught in hailstorms have been forced to crash land.
Roopkund hail storm, India, ninth century
What happened and when?
Roopkund Lake in the Himalayas is the mysterious ‘Lake of skeletons’.
The lake is at a height of sixteen thousand feet. In 1942, a park
ranger discovered hundreds of skeletons on the edge
of and inside the lake. A study of the skull fractures
revealed that the deaths were caused by a massive
hail storm. With no shelter available, some 600
people perished after being battered by hailstones At higher levels,
the size of cricket balls. What were they doing the droplets
there? They were possibly on a pilgrimage. Studies freeze, forming
of the remains indicate that this happened in the small hailstones,

under the thick layer of hail. More than
600 cattle, sheep, and goats were killed.

were injured. Large hailstones rained for two hours. Houses, crops, and
trees were destroyed, and a large number of animals were killed in four
hundred villages.
