The Fort Selkirk volcanic field near the junction of the Yukon and Pelly rivers in central Yukon is the northernmost Holocene volcanic field in Canada. It consists of a sequence of valley filling alkaline olivine basalt and basanitic lava flows succeeded by construction of three nephelinitic pyroclastic cones and lava flow aprons. The Ne Ch'e Ddhawa pyroclastic cone (Wootten's Cone) is composed primarily of hyaloclastite tuffs, breccias, and pillow breccias erupted subglacially during the late Pleistocene (Jackson, 1989). The youngest cone, Volcano Mountain, produced young nephelinitic lava flows that remain unvegetated and appear to be only a few hundred years old. However, dating of sediments in a lake impounded by the lava flows indicated that the youngest flows could not be younger than mid-Holocene and could be early Holocene or older (Jackson and Stevens, 1992).

The Global Volcanism Program is not aware of any Holocene eruptions from Fort Selkirk. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Fort Selkirk 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.

Volcano Mountain, shown above, is a pyroclastic cone of the Fort Selkirk volcanic field in the central Yukon Territory and is Canada's northernmost Holocene volcano. Volcano Mountain comprises a cinder cone and a series of lava flows that traveled to the NE and SW. The Fort Selkirk volcanic field is located near the junction of the Yukon and Pelly rivers in central Yukon.

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.
