Where did the name Niagara come from?  (Back to the list of questions).

Old Niagara Falls MapsWhen European first explored the Great Lakes basin, the tribe of the "thundering waters" were the inhabitants of the Niagara region. Although their actual name has been long forgotten, they were referred to as "Ongniaahra" by the Iroquois Nation of which they were apart of. French settlers referred to them as the "Neutrals," referring to their position in the Nation as mediators between tribes.

When European explorers began mapping the Great Lakes basins, they used accounts from local tribes to fill in gaps. It is speculated that eastern tribes may have described the Niagara region by referencing the Neutral tribe by their Iroquois name: "Ongniaahra." Like with many Native American names, it was subsequently "basterdized" by map makers and eventually became Niagara.

It is not known whether or not "Ongniaahra" was the original name for the region or for its inhabitants. The Neutrals were wiped out by 1653 during a tribal war with the Seneca tribe.

How tall are Niagara Falls, really?  (Back to the list of questions).

If you read several Niagara Falls  informational placards, books and visitor's guides, you're bound to notice that many of them have different values for the height of the Falls. Which one is correct? Actually, all of them. Since the water flowing over the Falls is highly variable, depending on how much is diverted for power generation as well as seasonal flow, the depth of the water at the crest of the falls, as well as the water level at the pool below can vary, affecting the overall size of the Falls.  During peak tourist season, when the Falls see high volumes of water, there is a slight bump in elevation, as the depth of water at the crest increases by several feet, but this is offset greatly by an increase of water in the pool at the base. So as the water flow increases, the height of the fall decreases.

There are several other reasons to consider. Some people measure to the boulders below, which in the case of the American Falls, can reduce the total height significantly. Some measure to the river's water level in the pool, while others take the distance to the bottom of the pool.  Many numbers are rounded, distorted by heresy, or just estimated incorrectly.
