Re: giant

Thanks! I was very lucky as only half an hour before I was on Mt. Shasta trying to get my rental car out of the snow! The next day was quite cloudy so this was the best I saw. Hopefully one day I'll be able to go back and climb it.

Superb image of a giant

Supposedly bigger than neighboring Rainier though a few hundred feet shorter. Love the alpenglow, reminds me of a view of Denali. Speaking of Denali, any volcanos or seismic activity in the Alaska Range? And I don't mean the hot springs along the lowest flank of the Kahiltna Glacier. Something hotter, with magma and lower potassium than that. Superb picture 10/10

Re: Superb image of a giant

Glad you like the picture, I had looked forward to seeing this volcano for a long time and was thoroughly impressed. Not an expert on Alaskan tectonics so will offer just what some quick research has thrown up. Volcano-wise there's only one spot I'm aware of that had some activity about 3000 years ago at Buzzard Creek (http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Buzzard%20Creek). The nature of the tectonics is that there's a lot of rock for magma to rise through to get to the surface in this area so one factor in there being not too much seen. Nearer the coast like the Aleutians and Cascades there's less rock to go through so there are more volcanoes to be seen there. In the past it seems there was perhaps an island arc that got accredted on to Alaska as subduction occurred but most trace of that is gone now. Earthquake wise there's plenty going on as the Pacific Plate heads under the North American Plate causing a lot of pressure to build up throughout the area. The Denali Fault produced a very large (~M 7.9) earthquake in 2002 as well as more frequent smaller events. There's a nice graphic here: http://en.wikipedia.org/wiki/File:Alaska_earthquakes.jpg
