The Volcano, Cinder cone in British Columbia, Canada.

The Volcano is a small cinder cone on a remote ridge in the Boundary Ranges of the Coast Mountains, about 60 km northwest of Stewart, British Columbia. It rises to 1,656 m with a prominence of 311 m above the northern flank of a glaciated U-shaped valley. The cone is built of loose volcanic ash, lapilli-sized tephra and volcanic bombs, and its form has been reduced by alpine glacial erosion. The vent area holds bombs up to 0.5 m long and small sulfur deposits.

The Volcano is the southernmost of the ten cones of the Iskut volcanic field and the most recent to erupt. Tree-ring and radiocarbon dating identify two eruptive phases, the first about 360 years ago and the latest possibly only 150 years ago, making it the youngest known volcanic mountain in Canada. Surveyor Fremont Morse noted a lava flow in 1905 and judged it probably less than fifty years old; a 1904 eruption is listed in some documents but the Smithsonian's Global Volcanism Program treats it as uncertain.

The volcano's name comes from Lava Fork, the stream whose headwaters lie near the cone and whose valley carried its lava flows 5 km south across the Alaska border. Surveyor Fremont Morse, working for the International Boundary Commission, reported one of these flows in 1905 and judged it probably less than fifty years old.

The cone sits about 60 km northwest of Stewart, near the head of Lava Fork, on a ridge flanking a glaciated U-shaped valley. There is no road or trail to the summit; access is by helicopter or on foot through trailless alpine terrain. The lava flows run 22 km from the cone, crossing into Alaska and damming the Blue River to form several lakes.

Surveyor Fremont Morse noted one of its lava flows in 1905 during an International Boundary Commission survey, and in 1906 he judged the most recent flow had probably occurred less than fifty years earlier. Tree-ring and radiocarbon dating later placed the two eruptive phases at about 360 and 150 years ago.
