'Frozen' Niagara Falls drawing tourists to winter spectacle

The winter's deep freeze has transformed Niagara Falls into an icy spectacle, encasing the trees around it into crystal shells and drawing tourists.
The Niagara River keeps flowing below the ice cover, so the falls aren't completely frozen over. But the massive ice buildup near the brink has become a tourist magnet for the second straight year after several relatively mild winters.
Visitors have been flocking to Niagara Falls State Park, next to the American Falls, one of three waterfalls that make up the natural attraction. The cold has created a thick coating of ice and snow on every surface near the falls, including railings, trees and boulders.

Things aren't expected to thaw out soon: Temperatures dipped to -22 Celsius in Niagara Falls this morning.
