The Falls recedes

heading dates from 2013-01-24 -P64

I found two parts of this article puzzling / incorrect:

1. "Niagara Falls recedes upstream." Perhaps the view of the Falls recedes upstream, but I don't think the falls themselves do. Was this an attempt at a literary florish? I just found it confusing.

2. "and the falls began their long journey southward toward Lake Ontario" Here, the falls are on the move again, Lake Ontario is south of the falls, and 30 km is apparently a long journey. At best, confusing.

The Falls does recede upstream. Primarily it has in the past receded from the escarpment south toward Lake Erie and on the American side it does in the present crumble rather than recede much.

According to "Niagara Falls Geology Facts & Figures" at Ontario's Niagara Parks, "Niagara Falls has moved back seven miles in 12,500 years [south toward Lake Erie] and may be the fastest moving waterfalls in the world." There an overhead photo image is marked with dotted lines depicting the brink of the Horseshoe Falls in six stages from 1678 to 2005. They show that the "horseshoe" has been created almost entirely since 1678, when the brink was nearly straight. And that the horseshoe deepened --the Falls receded-- only slowly during the last century, 1886 to 2005, perhaps because much water has been diverted for power production.

Evidently the distance from the escarpment to the Falls is 11-12 km and that is a long journey by water erosion --about one meter per year on average. --P64 (talk) 18:53, 24 January 2013 (UTC)

I have fixed the confused/confusing text, among other changes, while segregating the geology in a new second paragraph and expanding it. This revision only begins to make good use of the material introduced immediately above. --P64 (talk) 20:30, 24 January 2013 (UTC)
