Niagara Falls

The same view a century later in 2005:

As mentioned in my previous post, the American side of Niagara Falls has changed a great deal, with erosion contributing to the large pile of rocks at the base of the waterfall.  In 1969, the water was diverted away from the American Falls, and work was done to stabilize it and prevent it from becoming just a series of rapids, but the existing rocks at the base were not removed.  As a result, the American Falls looks far less dramatic than it did 100 years ago, but the Falls nonetheless remain just as popular a tourist destination as ever.

At the base of the Falls is the Maid of the Mist, one of of two such boats that brought tourists to the base of the Falls.  Both of these boats burned in a fire in 1955, but newer Maid of the Mist boats continue to give tours of Niagara Falls.

The scene in 2005:

Niagara Falls has been a popular tourist destination since the 19th century, and was particularly popular as a honeymoon destination – perhaps that was the occasion for the young couple in the first photo.  Much has changed at the Falls since then, both the surrounding area and the waterfalls themselves.  In the distance, the high-rise buildings reflect the increasing popularity and tourist-oriented nature of Niagara Falls, and if the cameras were turned around, one would see even more striking changes on the Canadian side of the gorge.

One obvious change with the American Falls is the accumulation of rocks at its base.  The 2005 photo shows a much shorter distance from the top to the rocks at the bottom, which were deposited by rock slides and erosion caused by the waterfall’s steady retreat upstream.  By the 1960’s, there was great concern that the American Falls would erode to the point where they would become a series of rapids rather than a true waterfall, so the water was diverted from it and the American side of the Falls was temporarily shut off.  Geologists secured and stabilized some of the most erosion-prone areas, but they determined that it would be too costly to remove the rocks that had already fallen.
