Abstract
Volcanic ash is not only a hazard during an eruptive event; in strong winds, previously deposited loose volcanic ash can be picked up and reworked into dust clouds. Resuspension and transport of fine-grained volcanic ash from Katmai National Park and Preserve, Alaska has been observed and documented many times over the past several decades and has likely been occurring throughout the time interval since the 1912 Novarupta-Katmai eruption (Hadley et al. 2004). This eruption, the largest in the world during the 20th Century, produced approximately 4 cubic miles (17 cubic km) of ash deposits and 2.6 cubic miles (11 cubic km) of pyroclastic material that filled nearby valleys, creating what is today known as the Valley of Ten Thousand Smokes (VTTS; Fierstein and Hildreth 1992). Ash in this valley is up to 660 feet (200 m) thick and the valley remains almost entirely free of vegetation (Figure 1).
