Description

From Wood and Kienle (1990) [1] : "The Ingakslugwat Hills volcanic field consists of >32 small cinder cones and 8 larger craters with associated flows, all covering an area of >500 square km. Older vents are low, wide cones with saucer-shaped craters up to 1.5 km in diameter; younger eruptions formed relatively small, steep cones 30 to 90 m high and 90 to 150 m wide. Numerous small spatter cones and cinder cones ~30 m high occur on the northwest side of the volcanic field. Some cones are aligned west-northwest, apparently defining a fracture. One low cone with a lake ~400 m across may be a maar. The rocks are chiefly alkali olivine basalt with lesser amounts of basanite and nephelanite. The eruptive history of this field is unknown, but the well-preserved volcanic morphology suggests that some of the activity occurred in the Holocene.
"Inclusions of lherzolite, layered gabbro, and granular gabbro occur in nephelnite ash and in an alkali basalt flow erupted from a cone in the southwest part of the Ingakslugwat Hills."

Name Origin

"Ingakslugwat Hills" is a Yup'ik name reported in 1948 by U.S. Coast and Geodetic Survey, who reported it means "little old small mountains". They are referred to as "The Volcanoes" by the "bush pilots", according to Orth, 1965 (Orth, 1971).
