The closest observatory to Mount St Helens
Johnston Ridge Observatory is named for volcanologist David Johnston, who was camped at the site when Mount St. Helens erupted on May 18, 1980. His final words – called in via shortwave radio – were …“Vancouver, Vancouver, this is it!” Johnston’s body has never been found.
