At least one lava flow from The Volcano was notified by a surveyor named Fremont Morse in 1905 during a survey for the International Boundary Commission. In 1906, Morse wrote that the most recently erupted lava flow had "probably occurred within less than fifty years".[12] Since Morse's report, tree ring and radiocarbon dating techniques have been used to establish the dates of The Volcano's two volcanic phases. The first is estimated to have occurred about 360 years ago and the latest possibly took place only 150 years ago.[4][5] This indicates that The Volcano is the youngest known volcanic mountain in Canada and that its volcanic activity is recent compared to many other volcanoes in British Columbia.[4] In several documents, the last eruption of The Volcano is written to have occurred in 1904.[13][14] However, according to the Smithsonian Institution's Global Volcanism Program, this eruption is considered uncertain.[1]
