In 1845 the British Lieutenant Henry Warre sketched an eruption of Mount St. Helens from the west. The eruption plume is correctly shown originating from the N flank. The volcano was frequently observed in eruption from November 1842 until September 1845. Goat Rocks lava dome on the N flank was active at this time.
