There's disagreement in the text about the location and extent of the Niagara Escarpment, especially in the United States. I'm also worried about a slight Canadian bias to the article. Someone knowledgeable should fix both of these issues.

[edit] What's Contradictory

"The Niagara Escarpment is a long escarpment or cuesta running through southern and central Ontario, Canada and western New York State. It is composed of the Lockport geological formation of Silurian age, and is similar to the Onondaga geological formation, which runs parallel to it and just to the south, in New York and eastern Ontario."

The first paragraph gives the more popular idea of where the Niagara Escarpment is.

"Thje Niagara Escarpment is the most prominent of several escarpments formed in the bedrock of southern Ontario. It is traceable starting in eastern New York and along a westerly direction across the Niagara River into Ontario where it stretches along the Niagara Peninsula and northerly to Georgian Bay near Collingwood. It then turns westerly toward Owen Sound at which point it turns northerly to form the spine of the Bruce Peninsula, the Manitoulin and other islands located in northern Lake Huron where it turns westerly into the Upper Peninsula of northern Michigan. It then extends southward from the area of Sault Ste. Marie into Wisconsin following the Door Peninsula and western coast of Lake Michigan, ending near Chicago."

This paragraph gives more locations. Some are more specific to the first paragraph, but others are new.

Approximate extent of the Niagara Escarpment.

The brown area of this image implies the Niagara Escarpment exists in even more locations.

And that's what self-contradictory about this article. Perhaps when I'm climbing down the Niagara Escarpment to Lake Michigan at my parent's cottage in Door County, I'll take a picture and upload it. -Acjelen 21:07, 9 Jun 2005 (UTC)

Oh, and I'm not "confused" about anything. -Acjelen 21:14, 9 Jun 2005 (UTC)

So why don't you add the information to trace it farther west? I'm familiar with the section from eastern NY into the Niagara Penninsula of Ontario. An editor familiar with the section in Ontario added info and photos on that section. If each editor adds the part that (s)he is familiar with, we'll eventually get the whole of it. Go for it!

My main concern is that the first and the second paragraphs should agree. I have attempted that. If we are to expand this article, it may need a "Location" section division to keep the introductory paragraph introductory. It would also be nice if the formation of limestone was a little more explicit. -Acjelen 12:13, 10 Jun 2005 (UTC)

As to the map, a possible solution is about to appear. I have created a map of the Great Lakes region with the escarpment plotted on it. The old map is not merely "contradictory", but just plain wrong. What it shows is not the Escarpment, but the extent of Silurian rocks associated with the Niagara Escarpment formation. I have marked, in red, places where there is an actual escarpment or ridge. This information has been compiled from several websites. Kelisi 17:17, 22 December 2005 (UTC)

If the current map in the article is correct, then the text should be edited to omit any mention of the escarpment reaching into Illinois or "northwest of Chicago." According to that map, it clearly ends well within Wisconsin. --mtz206 03:19, 9 February 2006 (UTC)

[edit] Category

Is there consensus that we can create a wikicategory for Niagara Escarpment? There are so many related articles about parks and trails, etc. Blacknail 20:42, 16 December 2005 (UTC)

I agree. The escarpment affects quite a few states/provinces. How far should the category go? Should it include the counties? What about Lake Winnebago, which was formed because of the escarpment? Royalbroil ^T : C 03:17, 1 February 2007 (UTC)

[edit] Multiple geography of categories

Aren't Category:Geography of Hamilton, Ontario and Category:Geography of Niagara Region, Ontario both subcategories of Category:Geography of North America? We should not cherry-pick which local geography categories are used with this article. -Acjelen 14:31, 29 May 2007 (UTC)
