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.

The Global Volcanism Program is not aware of any Holocene eruptions from Ingakslugwat Hills. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Ingakslugwat Hills page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Ingakslugwat Hills.

This relatively featureless area in this NASA Landsant image (with north to the top) of the Yukon-Kuskokwin delta contains part of the Ingakslugwat Hills volcanic field. This monogentic volcanic field consists of at least 32 small cinder cones and 8 larger craters covering an area of more than 500 sq km. Numerous small spatter cones and cinder cones dot the NW side of the volcanic field. The latest activity was considered to have occurred during the Holocene. One low cone containing a 400-m-wide lake may be a maar.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. 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.
