AVO Image

Charlie Bacon (USGS volcanologist) draws the boundaries of prehistoric lava flows from Mount Veniaminof, Alaska, onto a map. This information shows the regions covered by past lava eruptions and aids in estimating the size and style of future volcanic events. Volcanologists in Alaska often need to carry firearms (foreground) and pepper spray as protection against grizzly bears. The backpack contains food and survival gear, and a two-way radio to call the helicopter pilot. Charlie's overalls are a fireproof fabric for safety in case of a helicopter accident, and the orange color helps the pilot find the volcanologist.
