The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

The Ingakslugwat Hills consist of at least 32 small cinder cones and 8 larger craters covering an area of more than 500 sq km in the Yukon-Kuskokwin delta area of SW Alaska. Numerous small spatter cones and cinder cones of the Ingakslugwat Hills range from 8 to 190 m in height; many are concentrated in the NW side of the volcanic field. The latest activity was considered to have occurred during the Holocene (Moll-Stalcup, in Wood and Kienle 1990). One low cone containing a 400-m-wide lake may be a maar. This dominantly alkali olivine basaltic volcanic field also contains basanitic and nephelinitic rocks, some with inclusions of lherzolite and layered and granular gabbro.
