Background

The volcano was constructed above Cretaceous and Jurassic sedimentary rocks. A lake temperature of 25 degrees Centigrade and a pH of 1 were measured in 1982. The fumaroles, which are actively depositing sulfur, were all at the pressure boiling point in 1982 and heated up to 114-118 degrees in 1991. The fumaroles are located on the NE wall of the 160 x 200 m wide crater lake; some fumaroles are subaqueous and produce turbulence on the surface of the blue-green lake. Unglaciated and relatively uneroded lava flows are found on the NW flank of the volcano. The age of the most recent eruptions from Douglas is not known, but Nye et al. (1998) considered activity to have occurred during the Holocene.
