This shot was taken from the ISS (International Space Station) on September 20, 2012, and shows the region around Mount Shasta, a 4300 meter peak in northern California. It’s technically dormant – it erupted last in 1786. In geologically recent history it’s erupted every 600 years or so, but that’s not a precise schedule, so geologists keep an eye on it, as they do many of the peaks in the Cascades. As well they should.
