ice bridge

Standing on the brink of the rock at the point where the ice-bridge began, he contemplated the chances of Rattle Water.

A party of friends met them with a huge touring car, and carried them on a flying 22 trip to the ice-bridge at Niagara Falls.

Then suddenly his snarl turned to a mournful howl that was lost in frightful cracking as the ice-bridge broke away.

The vast quantities of ice pouring over the precipice would freeze together, agglomerate, and form an ice-bridge.
