Mount Douglas is a stratovolcano located south of Kamishak Bay at the northern part of the Alaska Peninsula. The mountain was officially named in 1906 after nearby Cape Douglas based on a 1904 report by USGS geologist G. C. Martin. The Alaska Volcano Observatory currently rates Douglas as Level of Concern Color Code Not Assigned. The volcano has a warm and highly acidic crater lake approximately 160 m (525 ft) wide. In 1992, the lake has a temperature of 21°C and a pH of 1.1. At the north flank of the volcano unglaciated and relatively uneroded lava flows are found. The last eruption was considered to have occurred during the Holocene (Nye et al.,1998).
