"The Alaska Peninsula, Kodiak Island, Kenai Peninsula, and Cook Inlet areas are the most likely to be covered with volcanic ash, which is actually pulverized rock from the volcanic explosion. 'Fresh volcanic ash' may be harsh, acidic, gritty, and smell like sulphur. Heavy ashfall may reduce sunlight, causing a sudden demand and possibly brownouts of electrical power. Ash can clog watercourses, sewage plants, and all kinds of machinery. A one-inch layer of ash weighs ten pounds per square foot, and fine ash is extremely slippery, hampering both driving and walking."
