This is cool.......
I'm looking at a glacier right now (okay, it was 10 minutes ago) that is 60% of the size it was 50 years ago.
The glacier you speak of is growing rapidly mainly because of the major eruption in 1980 blowing the top off and creating a massive 1 mile wide crater. Then add recent (2004)magma, volcanic and seismic activity which has created a growing dome in the crater it has allowed a shaded area for a new glacier to form. There's always been a glacier on Mt St Helen's, it was just blown away in 1980 and is now reforming, all the Cascade glaciers are still intact.

Crater Glacier and other new rock glaciers
Main article: Crater Glacier
During the winter of 19801981, a new glacier appeared. Now officially named Crater Glacier, it was formerly known as the Tulutson Glacier. Shadowed by the crater walls and fed by heavy snowfall and repeated snow avalanches, it grew rapidly (14 feet (4.3 m) per year in thickness). By 2004, it covered about 0.36 square miles (0.93 km2), and was divided by the dome into a western and eastern lobe. Typically, by late summer, the glacier looks dark from rockfall from the crater walls and ash from eruptions. As of 2006, the ice had an average thickness of 300 feet (100 m) and a maximum of 650 feet (200 m), nearly as deep as the much older and larger Carbon Glacier of Mount Rainier. The ice is all post1980, making the glacier very young geologically. However, the volume of the new glacier is about the same as all the pre1980 glaciers combined.
With the recent volcanic activity starting in 2004, the glacier lobes were pushed aside and upward by the growth of new volcanic domes. The surface of the glacier, once mostly without crevasses, turned into a chaotic jumble of icefalls heavily criss-crossed with crevasses and seracs caused by movement of the crater floor. The new domes have almost separated the Crater Glacier into an eastern and western lobe. Despite the volcanic activity, the termini of the glacier have still advanced, with a slight advance on the western lobe and a more considerable advance on the more shaded eastern lobe. Due to the advance, two lobes of the glacier joined together in late-May 2008 and thus the glacier completely surrounds the lava domes. In addition, since 2004, new glaciers have formed on the crater wall above Crater Glacier feeding rock and ice onto its surface below; there are two rock glaciers to the north of the eastern lobe of Crater Glacier.
An ignorat attempt to disprove GW.
Not at all. I don't plan on buying into the panic factor. Earth changes. Has for thousands upon thousands of years. Weather patterns change, they have for thousands upon thousands of years.
Then why bring up an extreme anomaly, that has nothing to do with GW at all?
I don't buy into the chicken little we're all going to die (which we all are but that's another topic...), just common sense and sustainability.
You either bring this up from regurgitating and spewing righty talking points, or you're ignorant on Mt St Helen's.
Um ... actually it does disprove it in a round about manner. Namely because the glacier would not be reforming as predicted if GW was real ... now would it ...
So if something happens in moderation for a very long time, extreme changes can't hurt it?
Sure it could. Nothing about Global Warming says that in 2009, nothing cold exists, or there can't be new glaciers, or the like.
Duh, you are the one that brought up "GW". Look back there jack, I said, "This is cool". I also said, "Imagine that".... Get that bug out of your ass, ass.
