S1:E6 Assault on Niagara
First Aired: December 27, 2011
Three sites, hundreds of tons of dangerous rock, fifteen days. The crew reports to Niagara Falls State Park and is given a mammoth task: make the park safe for the public. They must address several areas in which dangerously loose rock threatens to topple down the slope and injure and destroy anyone or anything in its way.
