The Kookooligit Mountains are a 30 x 40 km wide shield volcano of Pleistocene-to-Holocene age in north-central St. Lawrence Island. The 673-m basaltic shield is composed of massive columnar-jointed lava flows that are overlain by more than 100 small cones (20-60 m high). Most of the cones are aligned E-W along the crest of the elongated shield volcano.
The Global Volcanism Program is not aware of any Holocene eruptions from Kookooligit Mountains. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Kookooligit Mountains page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.
|Feature Name||Feature Type||Elevation||Latitude||Longitude|
|Atuk Mountain||Cone||63° 36' 0" N||170° 26' 0" W|
|Kookoolit Hill||Cone||103 m||63° 40' 0" N||170° 20' 0" W|
|Pyroclastic cones dot the surface of the Kookooligit Mountains in north-central St. Lawrence Island in the Bering Sea. Kookooligit is a 30 x 40 km wide, 673-m-high shield volcano of Pleistocene-to-Holocene age overlain by more than 100 small cinder cones, most of which are aligned E-W along the crest of the elongated shield volcano. The cones were the source of dominantly alkali basaltic and basanitic lavas flows.

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.
