Video captures 'breaking glass' ice phenomenon at Leeds reservoir

John Keigley was stunned to spot ice on the surface of East Ardsley Reservoir breaking like glass during a recent visit.

Ice stacking occurs when thin sheets of ice are blown across the water and break into shards on the shore.

The ice makes a hypnotic sound similar to glass shattering.

"I was just on a walk around the reservoir when I heard this bizarre noise," said 44-year-old sales manager John.

"I couldn't work out what it was at first, it sounded like glass shattering.

"It was totally surreal. I could see it was collecting at the side of the shoreline and I've never seen anything like it.

"It was such a great sound."

As warmer air blew across the brittle ice in the reservoir the covering began to move in large sheets.

The video then shows the ice forming into 'shard-like' sheets before melting.
