Mount Jeffersons[edit]

Presidential Range fails to link here (erroneously) only bcz link is Mt. Jefferson; needs disamb eventually. --Jerzy 05:48, 2003 Dec 13 (UTC)

Oh yeah... Probably should move to Mount Jefferson (Oregon) etc, because I bet GNIS will tell us many more states have Jeffies somewhere in them. Stan 06:36, 13 Dec 2003 (UTC)

Sounds like an effective convention to me. Guess i should go reread Presidential Range and see if it mentions a state.... [wink] --Jerzy 15:15, 2003 Dec 13 (UTC)

It would make more sense to have the range's name as the disambiguator since some mountains sit astride borders and others share the same name as another mountain even within that border. In California, for example, there are several Table Mountains and Glass Mountains. Lakes are even worse. --mav 17:44, 13 Dec 2003 (UTC)
Also helps with the situation where highest point in a state is on a mtn whose peak is in the next state! --Jerzy 19:15, 2003 Dec 13 (UTC)
A little more specifically, i'd suggest that groups of mountains that don't constitute ranges be acceptable, e.g. Mount Jefferson (White Mountains) and Appalachian Mountains)? And that the largest group that eliminates the ambiguity is usually preferable. I.e., not Mount Jefferson (Presidential Range) since the Whites and Appalachians include the Prezzies and the Blue Ridge respectively, each along with others, and are probably better known that the Presidentials and Blue Ridge?
But am i right in assuming that "(Whites)", "(Presidentials)", and "(Appalachians)" are the wrong choice, esp. since they don't make clear whether to add "Mountains" or "Range" to complete the name? --Jerzy 02:50, 2003 Dec 14 (UTC)
There's no official standard, but when I add a disambiguator, I generally favor a word or phrase that is itself the name of an article, so searching will find - "Whites" is probably never used anywhere in WP to refer to any of the mountain ranges of that name, so "White Mountains" seems better. Either range or political unit would work, can't always do one or the other - there are three White Mountains in the US, more than one "Presidential Range" IIRC, not every mountain is part of a range, and as mav points out, states can have multiples too. Somewhere or another I've seen elevation used as disambiguator, but it will be a very long time before WP needs anything that desperate. Stan 04:12, 14 Dec 2003 (UTC)

The original article for the mountain in Oregon has now been moved to Mount Jefferson (Oregon). USGS GNIS listed 9 other mountains although they all exist in distinct states. I will change Mount Jefferson shortly to a disambiguation page. RedWolf 05:08, Jun 18, 2004 (UTC)

Williamette River??[edit]

I've lived in Oregon all my life (fifth generation Oregonian in fact), and have never heard of the "Williamette" River. There's a rather prominent N-S flowing river that runs most the length of the Willamette Valley and at Portland empties in to the Columbia River, but it's called the Willamette River (no "i" after the last "l").

Is "Williamette" a spelling that captures some important piece of historical context, or should the spelling be changed to accurately represent the river's name as it written absolutely everywhere today?

If there is some latent historical insight in calling it "Williamette," can someone please update the "Willamette River" article to document that fact? —The preceding unsigned comment was added by 69.9.146.66 (talk) 23:45, 21 January 2007 (UTC).

Though there might be some latent historical insight into typographical errors or possible sarcasm about same, usually it's better to just fix things like that yourself. :) Katr67 16:57, 22 August 2007 (UTC)

Nice image to add?[edit]

I ran across this lovely image, Image:Mt Jefferson Oregon.jpg, and thought it might be a good addition to the article, but I'm not sure we can justify three images and don't want to replace one without discussion. The image in the infobox is good since it shows the profile of the entire mountain. Thoughts? Katr67 16:57, 22 August 2007 (UTC)

Three images would be a bit much. The infobox image is rather lacking in contrast and clarity, but I agree we should keep it until we can get a better image that shows the full profile. I'll try to get one next time I'm in the area. With regards to replacing Image:Mount-Jefferson.jpg, I think Image:Mt Jefferson Oregon.jpg shows more detail on the mountain itself while the snow cover contrasts nicely with the infobox image which shows the late summer appearance of the mountain. Of course, Image:Mt Jefferson Oregon.jpg is my image, so I'm hardly unbiased. -- Headwes 21:42, 4 September 2007 (UTC)

Dormant/Extinct Line[edit]

I am removing this line as it is not cited.

In addition, volcanoes are considered active if they have had an eruption within 10,000 years. Mount Jefferson also is a volcano of the Cascade Volcanic Arc, which consists of volcanoes within the active Juan de Fuca subduction zone - current volcanoes and potential new ones can form and erupt at any time within this zone.

See the definition of active at Volcano#Volcanic_activity: "The Smithsonian Global Volcanism Program's definition of 'active' is having erupted within the last 10,000 years."

Jefferson's vague eruptive history is similar to Adams'. Considering this I think the opening line should not include any active/inactive designation. Rather than be vague in the summery, it should be noted later in the article how obscure Jefferson's latest eruptions have been. See the CVO USGS page for more details: http://vulcan.wr.usgs.gov/Volcanoes/Jefferson/ -- LQ (talk) 12:18, 17 May 2008 (UTC)

We had a similar debate at talk:Mount Hood#Dormant_or_active.3F over a year ago. Bottom line is that geologists don't use the terms active/inactive/dormant any more than medical personal use critical/serious/fair/good: both seem to be mostly for media sound bites, not for communicating useful information. Perhaps Jeff's condition can be stated the same as Hood: potentially active, though I don't know of a reference for Jeff.
Find a reference if you want to add the active volcano content. Most references I seen call Jefferson dormant or extinct. A volcano that has not erupted in the past 10,000 years is not always considered dormant or extinct ether; see Mount Cayley, another Cascade volcano, which is potentially active (it contains hotsprings and seismic activity) and has eruptions older than Jefferson.

Removed the 'extinct' part - it last erupted in the Holocene, so it can't be extinct. Guanlongwucaii (talk) 15:37, 20 May 2009 (UTC)Guanlongwucaii

Citation needed[edit]

"This was the only High Cascade mountain they named." It might be true that this is the only mountain the the range that they successfully named. If I remember correctly they named others as well but those mountains had already been named by the English and the new names did not stick. I'm not certain of my facts here but the statement certainly is ambiguous. I vote to remove it altogether. --DRoll (talk) 06:43, 9 November 2008 (UTC)
