Gem Glacier has not disappeared

In its third paragraph, http://en.wikipedia.org/wiki/Grinnell_Glacier says the Gem Glacier "disappeared in the 1990's".

To the contrary:

http://www.nrmsc.usgs.gov/repeatphoto/gg_trail11-98.htm says Gem Glacier "does not appear to have changed much" between 1911 and 1998 (leaving only 1999 for it to disappear, if it did so in the 1990's).

http://www.nrmsc.usgs.gov/research/glaciers.htm says it was being monitored in 2003 (it's been my experience that once something has disappeared, it's no longer monitored). Since it's the smallest glacier in Glacier National Park (according to http://www.nrmsc.usgs.gov/repeatphoto/gg_trail11-98.htm), it still is being monitored as far as I know.

In fact, it looks as large in http://www.philarmitage.net/glacier/glacier16x.html (the http://en.wikipedia.org/wiki/Grinnell_Glacier photo taken in 2005) as it did in the 1998 http://www.nrmsc.usgs.gov/repeatphoto/gg_trail11-98.htm photo.

Gem Glacier, 48.747ºN 113.727ºW, is in the upper right quadrant of the http://www.philarmitage.net/glacier/glacier16x.html photo. From this camera angle, it's what looks like a snow drift, above Grinnell Glacier, about halfway up the face of the Garden Wall, on the rock shelf between Mount Gould and the Garden Wall, not the long line of snow, at about the same altitude to the left of it, on Mount Gould.

http://www.bigskyfishing.com/National_parks/glacier/grinnell-glacier-gallery/head-grinnell-glacier.shtm has a more head-on photo of Gem Glacier and in http://www.terragalleria.com/parks/np-image.glac34126.html you can see its icy terminus.24.245.1.26 22:40, 14 January 2007 (UTC)[reply]

Good work...I made the proper adjustments. An efort to better document all the remaining glaciers is underway and Gem Glacier will have it's own article soon, or feel free to create one yourself if you wish. Thanks again for the excellent summary above!--MONGO 06:02, 15 January 2007 (UTC)[reply]

Assessment

I have rated this article a "B" rating due to a storng probablility that not a lot more information is coming to be available anytime soon. I think the article is almost as comprehensive as it can get for right now.--MONGO 07:51, 5 March 2007 (UTC)[reply]

Current size

In thinking that 1993 is pretty old for a current measurement, I did a little Google searching. I found an article from May 2005 that implies its size is 110 acres (a quarter of 440 acres) or about 0.45 km^2. This is a very poor source, IMO, primarily because it's not very exact, but also because it might stir POV questions in some. A more scholarly source from 2001 says that it lost 0.17 km^2 between 1993 and 2001, so indulging in some possible WP:SYN for this talk page, that leads me to 0.61 km^2 in 2001 (which, if one assumes more accuracy than it probably deserves from the previous article, that it lost 0.16 km^2 between 2001 and 2005). In short, I think it'd be nice if we had some fresh, reliable sources about this glacier that we could use to give a more recent size value for (without resorting to synthesis), but I couldn't find any.

I'm looking around. Appears that the Glacier Monitoring webpages that were here are currently under reconstruction, so I added a few new ones and did some updates.--MONGO 19:09, 29 August 2007 (UTC)[reply]
