What is Mount Garibaldi?
{{no sources|date=January 2024}} [[File:Mount Garibaldi.jpg|thumb|right|300px|Mount Garibaldi, as seen from Squamish.]] '''Mount Garibaldi''' is an [[Soil erosion|eroded]], dacitic [[Stratovolcano|strato volcano]] in southwestern [[British Columbia]]. Both Garibaldi and [[Mount Baker]] to its south are part of the [[Cascade Volcanic Arc|Cascade]] volcanic arc. Mount Garibaldi, 80&nbsp;km due north of [[Vancouver]], is made up of Mount Garibaldi, [[Atwell Peak]], and Dalton Dome. This [[Pleistocene]] volcanic center is part of a volcanic field that contains some 13 [[vents]] in an area 30&nbsp;km long by 15&nbsp;km wide, much of which is in [[Garibaldi Provincial Park]]. The history of Mt Garibaldi involves an initial period of [[volcanism]] (200,000-300,000 years ago) followed by a period of [[quiescence]]. Renewed activity in the last 50,000 years has rebuilt the edifice in a series of violent eruptions. As successive [[pyroclastic flows]] travelled down the mountain's gentle slopes and were deposited, the volcano took on a broad, conical form. Part of the volcano's southwest flank built out onto thick glacial ice filling the [[Squamish River]] valley. Subsequent rapid melting of the ice at the close of the last ice age removed support from the western part of the cone. The volcano collapsed, producing much of the existing rugged topography of Mount Garibaldi and Atwell Peak. This catastrophic failure left a [[Scarp (landform)|scarp]] on which is exposed the internal structure of the volcano and a debris fan with an estimated volume of 150,000,000 m at the foot of the mountain north of the town of [[Squamish]]. As valley [[Glacier|glaciers]] retreated, two [[lava]] flows erupted [[Clinker Peak]], immediately north of Mt. Garibaldi. The northernmost [[Rubble Creek]] flow was party confined by a wall of ice, resulting in a lava flow over 244&nbsp;m (800&nbsp;ft) thick. The steep, northern edge of the Rubble Creek flow party collapsed several times, most recently in [[1855]]-[[1856]]. The village of Ga
