Description: On November 10 and 13 strong winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes picked up loose volcanic ash erupted during the 1912 Novarupta-Katmai eruption. The resulting resuspended ash cloud extended over Shelikof Strait and Kodiak Island.

This phenomenon is not the result of recent volcanic activity and occurs seasonally in the spring and fall during times of high winds and dry snow-free conditions in the Katmai area and other young volcanic areas of Alaska. All of the volcanoes of the Katmai area (Snowy, Griggs, Katmai, Novarupta, Trident, Mageik, Martin) remain at color code GREEN.
