US weather: Huge 'ice fountain' forms in US park

A huge ice fountain has formed in a New York park, as cold weather continues to grip the eastern half of the US.

Temperatures are 20-40F below normal for February from the Mid-Atlantic to the South.

Letchworth State Park's fountain runs year-round from a stream, but has been encased in ice as temperatures continue to plummet.

The icy formation - around 50ft tall (15.24m) - is continuing to draw crowds, with park officials suggesting it could still grow.
