There are no Holocene eruptions known for Alligator Lake. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

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. Additional discussion of data sources can be found under Volcano Data Criteria.

A group of basaltic cones and lava flows (the Miles Canyon basalts) in south-central Yukon near the capital city of Whitehorse was considered to be of Pleistocene age (Wheeler, 1961). The upper part of the Alligator Lake volcanic complex, consisting of two well-preserved cinder cones capping a small shield volcano, probably post-dates local Holocene glaciation (Eiche et al., 1987). Lava flows from both cones traveled to the north and were erupted simultaneously. Their compositions range from alkali olivine basalt to basanitic. Flows from the NE cone are the largest, extending 6 km from the cone and expanding to a width of 10 km at the terminus. Portions of the flows contain spinel lherzolite and granitoid xenoliths and megacrysts of olivine, pyroxene, and spinel.
