MMF is a fumarole on Mammoth Mountain. Vent temperature is measured each hour and recorded on an electronic datalogger. Gas chemistry and water isotopes have been collected on several occasions. Using this approach, we carefully monitor vent gas temperatures of Mammoth Mountain, which may change as the volcanic system changes.For more information on this fumarole, visit our helium discharge webpage.
