Winds Blow 100-year-old Ash Over Alaska:

Winds over Kodiak Island, Alaska, are stirring up ash from 1912 when Novarupta erupted the largest volcanic blast of the 20th century. Gusts of more than 52 mph have whipped up a haze of the ash that drifted 4,000 feet high, requiring an aviation alert on Tuesday.

The ash layer from the eruption is up to 700 feet in some parts of what is now the Valley of 10,000 Smokes. This year's lack of snow cover coupled with the strong winds this week, sent some of that ash skyward. During the volcanic eruption in June 1912, Novarupta spewd ash as high as 100,000 feet over the sparsely populated Katmai region.
