2015 - Squamish BC - Mt. Garibaldi + Streetlight
Took a drive up Sea to Sky Highway 99 to Squamish and then north past Brakendale to Fergies at the Sunwolf Outdoor Centre on the Cheakamus River for Sunday brunch. Approaching Squamish, Mt. Garibaldi dominates the skyline.
Mount Garibaldi is a peak in the Coast Mountains east of the Cheakamus River north of town of Squamish at the head of Howe Sound. Glacier-capped, it is 8,787 ft (2,678 m) high and is the focus of Garibaldi Provincial Park. Established in 1927 the park is now a popular year-round recreational district. Capt. George H. Richards of the survey ship “Plumper” named the peak around 1860 for the Italian patriot.
Mount Garibaldi is a potentially active stratovolcano. It is one of the most recognized peaks in the South Coast region, as well as British Columbia's best known volcano. It lies within the Garibaldi Ranges of the Pacific Ranges.
This heavily eroded dome complex occupies the southwest corner of Garibaldi Provincial Park overlooking the town of Squamish. It is the only major Pleistocene age volcano in North America known to have formed upon a glacier.
The Garibaldi Volcanic Belt is the northern extension of the Cascades Volcanic Belt in the northwestern Unitied States. This volcanic belt is the result of subduction of the Juan de Fuca tectonic plate beneath the North American tectonic plate; the plates meet just seaward of the west coast of Vancouver Island. The volcanoes of this area generally are stratovolcanoes typical of subduction zone volcanoes.
The Garibaldi Lake volcanic field is of primary concern for the communities of Whistler and more importantly Squamish. Garibaldi volcano is an eroded, dacitic stratovolcano like Mount Baker ot the south. This Pleistocene volcanic center is a part of a volcanic field that contains some 13 vents in an area 30 km long and 15 km wide, much of which is in Garibaldi Provincial Park
The most recent period of activity occurred shortly after the disappearance of the glacial ice filling the valley, 10,700 to 9300 radiocarbon years ago, and ended with the eruption of a lava flow from the Opal cone.
Renewed volcanism in the Garibaldi area would pose serious threat to the local communities of Squamish and Whistler. Melting of remnant glacial ice could produce floods, lahars (mudflows), or debris flows.
Highway 99 linking Whistler and Squamish with Vancouver, is already plagued by landslides and dedris flows from the precipitous Coast Mountains. Eruption producing floods could destroy segments of the highway. Flooding and debris flows would have serious coneequences for the salmon fishery on the Squamish, Cheakamus, and Mamquam rivers. In addition explosive eruptions and accompanying ash could cause short and long-term water-supply problems for Vancouver and much of the lower mainland. The catchment area for the Greater Vancouver watershed is downwind from the Garibaldi area. Air-fall material could also have a deleterious effect on the ice fields to the east of Mt. Garibaldi, causing increased melting and spring flooding. This in turn could theaten water supplies from Pitt Lake as well as fisheries on the Pitt River.
