Talk:Don River (Ontario)

message: The Don River figures prominently among the humour of Wayne & Shuster. One was a golf tournament in an urban landscape, but the better-known sketch was a "Search for the Source of the Nile" type of expedition in which the duo, with porters, and appropriate safari clothing, followed the Don River to find its source, which turned out to be clearly marked with a sign, and a friendly attendant waited there, wearing white uniform, with a truck to take the safari members to a psychiatric institute.
Is there any merit in including this bit of "popular culture"? GBC 20:26, 27 September 2006 (UTC)
thread_title: Butt of Wayne & Shuster sketches

message: I'm reading this article very carefully, but still don't know exactly where the Don's mouth was prior to its two channelings.  Are their any accurate old maps showing the original course of the lower part of the river?  Also, does anyone have any maps, or can better describe the course, of the Lower Don when it was channeled in to Ashbridges Bay? --Criticalthinker (talk) 09:47, 23 September 2008 (UTC)
thread_title: Original and Natural Mouth of the Don

message: The geographic fact box says the river is in the "State [of] Ontario". Can "State" be changed to "Province"? It looks like it's been created using a defined term which generates the word "State". Yoho2001 (talk) 05:07, 9 April 2009 (UTC)

message: The first sentence currently says: 
I do not believe this is correct.  Garrison Creek would be the river that bounded the the west edge of the original settled area of Toronto.  Geo Swan (talk) 06:04, 5 February 2010 (UTC)
thread_title:  accuracy 

message: The article currently says: 
:"The Don Valley is notable because of its deep wide valley in the lower reaches. At the Bloor Street Viaduct, the valley is about 400 m wide while the river is only about 15 m wide.[18] This is due to its glacial origins. The Don River and its deep valley were formed about 12,000 years ago at the end of the Wisconsinan Glaciation. During that glaciation which lasted for 35,000 years, all of Ontario was covered in ice. As the climate warmed the glaciers began to melt. As the ice front retreated in southern Ontario, several rivers were formed that drained into Lake Iroquois, a glacier lake which was the precursor to Lake Ontario."
This seems to say that water flowing into Lake Iroquois carved the deep valley of the Lower Don.  However, the entire Lower Don was underwater, was a bay, at the time of Lake Iroquois.
The article also says: "As time progressed, isostatic uplift caused the earth's plate to rise and tilt. This caused Lake Iroquois to drain towards the south."
Actually the reason why Lake Iroquois was larger and deeper than Lake Ontario is that as the glacier retreated a lobe of the glacier continued to fill the St Lawrence River valley.  The lake drained when the glacier retreated.  The St Lawrence valley.  The last glaciation was merely the last of four, and the valleys of the larger rivers were carved by melt water of one melting glacier, refilled with till by a later glaciation.  This is why the current course of the Niagara Gorge takes a U-turn, when Niagara Falls encountered a gorge filled with till left by a previous version of the river during a previous glaciation.  Similarly, near the Elora Gorge on the Grand River there is another gorge, from a previous versionn of that river, during a previous glaciation.  It is still filled with glacial deposits, but its presence is apparent because wells dug over it have to be dug much deeper.  Geo Swan (talk) 04:38, 12 October 2014 (UTC)
