Attached is a recording made in Sherman Crater, the active crater at Mount Baker. The audio was made by Michael Dyrland during a gas sampling trip by volunteers with Mount Baker Volcano Research Center [MBVRC]. You can hear the roar of the gas as it escapes from a few of the hundreds if not thousands of fumaroles [gas vents], and bubbling, boiling water from tiny hotsprings. After St. Helens, Sherman crater is the hottest place in the Cascade volcanoes; even in winter there is bare ground at 9500' due to the hot ground, Sulphur gases and water vapor. MBVRC is an all-volunteer nonprofit organization that raises funds in support of volcano research at Mount Baker and informs the public via presentations about Mount Baker eruption history and hazards. Links to video taken in the crater are posted on the MBVRC website: http://mbvrc.wordpress.com/baker-facts/
Every year MBVRC volunteers climb the glacier and enter the crater to collect gas samples on behalf of US Geological Survey's volcano monitoring efforts. - Dave Tucker Research Associate, Geology Department Filmed By: Michael Dyrland 2nd Camera: Charlie Martin
