Aerial view of the south summit of Augustine Volcano. Steam rises from a prominent fumarole on the 2006 lava dome, as well as through a crack in the tephra rampart behind (south of) the dome. The small "dot" to the right of the far steam plume is the AVO real-time gas measuring station for detecting CO2 and SO2 gases. Photo taken September 29, 2016, by Game McGimsey, USGS/AVO.
