The winter's deep freeze has transformed Niagara Falls into an icy spectacle, encasing the trees around it into crystal shells and drawing tourists who are braving below-zero temperatures.
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.
NASA satellites also managed to capture the extent of the freeze from above showing an entire snow-covered northeastern state.
Visitors have been flocking to Niagara Falls State Park, next to the American Falls, one of three waterfalls that make up the natural attraction on the US-Canada border between New York State and Ontario. Days of subzero temperatures have 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 7 below zero in Niagara Falls on Friday morning.
