Royal Navy Commander George Vancouver and the officers of HMS Discovery made the Europeans' first recorded sighting of Mount St. Helens on 19 May 1792, while surveying the northern Pacific Ocean coast. [28] During Sugar Bowl time, the volcano first erupted quietly to produce a dome, then erupted violently at least twice producing a small volume of tephra, directed-blast deposits, pyroclastic flows, and lahars.[28]. Functioning as a gateway to the mountain, over 30 miles away, our goal is to educate visitors on the historical significance of the landscape before and during the eruption. Mount St. Helens showed significant activity on March 8, 2005, when a 36,000-foot (11,000 m) plume of steam and ash emerged — visible from Seattle. The summit of Mount St. Helens is at an elevation of 2,549 Meters (8,364 feet), at 46.20 N, 122.18 W. The summit stood at 9,677 feet before the May 18, 1980, eruption.

[5], Between 1980 and 1986, activity continued at Mount St. Helens, with a new lava dome forming in the crater. [47] Biological legacies are the survivors of catastrophic disturbance: they can either be alive (e.g., plants that survive ashfall or pyroclastic flow), organic debris, or biotic patterns left over from before the disturbance. [22] Beneath the Cascade Volcanic Province, a dense oceanic plate sinks beneath the North American Plate; a process known as subduction (geology). But the moon looks more like a golf course compared to what's up there. One of the nation's most dramatic natural events occurred close by in 1980, when Mount St. Helens erupted.

On July 10, 2008, it was determined that the eruption had ended, after more than six months of no volcanic activity. This small-volume outburst created large ash clouds, and mild explosions followed for 15 years. [65] The ash was also a source of income: it was the raw material for the artificial gemstone helenite,[66] or for ceramic glazes,[67] or sold as a tourist curio. Most notable was the closure of the Monitor Ridge trail, which previously let up to 100 permitted hikers per day climb to the summit. 18.
