Editing Mount Garibaldi (section)

===Background===
Mount Garibaldi is located on the east side of the Cheakamus River between [[Squamish, British Columbia|Squamish]] and [[Whistler, British Columbia|Whistler]] in New Westminster Land District.<ref name="KS"/> It lies within the Pacific Ranges Ecoregion, a mountainous region of the southern [[Coast Mountains]] characterized by high, steep and rugged mountains made of [[granitic]] rocks. Much of this [[ecoregion]] encompasses the Pacific Ranges in southwestern British Columbia, although it also includes the northwesternmost portion of the [[Cascade Range]] in [[Washington state]]. Several coastal islands, [[channel (geography)|channels]] and [[fjord]]s occur along the western margin of the Pacific Ranges Ecoregion. The Pacific Ranges Ecoregion is part of the Coast and Mountains Ecoprovince which forms part of the Humid Maritime and Highlands Ecodivision.<ref name="UD">{{cite book|last1=Demarchi|first1=Dennis A.|url=https://www2.gov.bc.ca/assets/gov/environment/plants-animals-and-ecosystems/ecosystems/broad-ecosystem/an_introduction_to_the_ecoregions_of_british_columbia.pdf|archive-url=https://web.archive.org/web/20210511210316/https://www2.gov.bc.ca/assets/gov/environment/plants-animals-and-ecosystems/ecosystems/broad-ecosystem/an_introduction_to_the_ecoregions_of_british_columbia.pdf|archive-date=2021-05-11|access-date=2021-11-12|title=An Introduction to the Ecoregions of British Columbia|publisher=[[Government of British Columbia]]|year=2011|pages=24, 25, 37, 38, 39, 47, 56, 113}}</ref>

The Pacific Ranges Ecoregion is subdivided into seven [[ecosection]]s, the Eastern Pacific Ranges Ecosection being the main ecosection at Mount Garibaldi. This ecosection is characterized by a rugged landscape of mountains that increase in elevation from south to north; the northern summits contain large [[icefield]]s. A transitional climate between coastal maritime and interior continental climates dominates the Eastern Pacific Ranges Ecosection. It is characterized by little precipitation and mild temperatures due to air from the [[Pacific Ocean]] often passing over this area. During winter, cold Arctic air invades from the Central Interior, resulting in extreme cloud cover and snow. A number of other volcanoes are situated within the Eastern Pacific Ranges Ecosection. This includes [[Mount Cayley]], which lies in the [[Squamish River]] watershed, and [[Mount Meager massif|Mount Meager]], which lies near the headwaters of the [[Lillooet River]].<ref name="UD"/>

Several rivers flow through the Eastern Pacific Ranges Ecosection, including the Fraser and [[Coquihalla River|Coquihalla]] rivers on its eastern side, the Cheakamus, Squamish and [[Elaho River|Elaho]] rivers on its western side and the Lillooet River lying in the middle. Coastal [[western hemlock]] forests dominate nearly all the valleys and lower slopes of this ecosection, the upper slopes containing [[subalpine zone|subalpine]] [[mountain hemlock]] forests and, to a lesser extent, [[Engelmann spruce]] and [[subalpine fir]] forests. Alpine vegetation lies just above the subalpine forests, which is normally overlain by barren rock.<ref name="UD"/> Wildlife such as [[grey jay]]s, [[chipmunk]]s, [[squirrel]]s, [[Northern flicker|flicker]]s,<ref name="AQW"/> [[Columbian black tailed deer]],<ref>{{cite web|url=https://bcparks.ca/news/pdfs/garibaldi_fact%20page.pdf|title=Garibaldi Provincial Park: 2010 Olympic Venue|publisher=[[BC Parks]]|page=2|year=|access-date=2022-09-24}}</ref> [[mountain goat]]s, [[wolverine]]s, [[cougar]]s and [[grizzly bear|grizzly]] and [[American black bear|black]] bears are locally present.<ref name="AQW"/> The communities of Whistler, [[Pemberton, British Columbia|Pemberton]], [[Mount Currie, British Columbia|Mount Currie]], [[Hope, British Columbia|Hope]] and [[Yale, British Columbia|Yale]] are situated within the Eastern Pacific Ranges Ecosection, all of which are connected to the [[Lower Mainland]] by a network of highways.<ref name="UD"/>
