Review
Via helicopter, speedboat, high-tech lab, and rope s end, and interviews with Falls historians, waterfall chasers, and search-and-rescue personal, we discover that Niagara has traveled more than seven miles upriver during its lifetime, and that the canyon etched in its wake provides a geological window into the Earth s past. Filmed with high-definition cameras and formatted in widescreen, this tape was designed as a showcase for HDTV ... , but it looks pretty darn good on regular TV, too. Three Stars. --Video Librarian
Product Description
Now, in an inspiring video event, we probe the secrets of Niagara Falls. From helicopter and speedboat, at high-tech labs and at rope's end, we join Earth scientists as they struggle to piece together the epic life story of North America's 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, Niagara's 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 Earth's crust like a knife. Its relentless procession has granted scientists a breathtaking window into the past. Soon enough, they've discovered, the Falls and its raging rapids will see to their own destruction. But not without leaving their lasting impression on the world, and on Niagara's admirers.
