Niagara Falls: Raging Rapids on DVD

Now, in an inspiring HDTV film, we probe the secrets of Niagara Falls. From helicopter and speedboat, at high-tech labs and at ropes end, we join earth scientists as they struggle to piece together the epic life story of North Americas most celebrated natural wonder. We experience the Falls that daredevils and stunters could never tame - the Niagara that is a vertical battleground between water and rock. Most think of it as a vision eternal, but in fact, Niagaras life has been a geological blink of the eye. Only a hundred and twenty five centuries ago it was unleashed, born of the last glacial surge that swept the continent. Since then, it has traveled more than seven miles upriver, cutting the Earths crust like a knife. It's relentless procession has granted scientists a breathtaking window into the past. Soon enough, they've discovered, the Falls and it's raging rapids will see to their own destruction. But not without leaving their lasting impression on the world, and on Niagaras admirers.
