Dans les hautes altitudes du parc national Yoho, les rochers content une histoire de la Terre d’avant les racines d’arbres et les sabots de cerf, quand un vaste océan hébergeait les débuts de la vie, en un endroit appelé les schistes de Burgess.

High in the mountains of Yoho National Park, the rocks tell a story of the Earth before tree roots and elk hooves, where a vast sea hosted the beginning of life as we know it, in a place we know as the Burgess Shale.

Les changements climatiques et hydrologiques rapides ont un impact négatif sur les montagnes de l’ouest canadien, et les communautés luttent pour comprendre et s’adapter à cette réalité nouvelle. Des observations rares et une capacité scientifique limitée entravent nos aptitudes à prévoir ces changements à travers le nord-ouest du Canada.

Les montagnes donnent autant lieu à des torrents qu’à de petits ruissellements d’eau douce. Des glaciers et des manteaux neigeux alpins qui fondent, des courants dégringolent parmi les montagnes et se dispersent dans les bassins versants.

High-elevation headwaters are the lifeblood for people and ecosystems alike. They provide the freshwater that pours through taps, supports the growth of food, and nurtures a diversity of freshwater species, including the iconic Kokanee Salmon.

Qu’est-ce qui vous vient à l’esprit lorsqu’on vous introduit au guidage autochtone? Si vous êtes comme la majorité, ce seront des images des années 1800 où des guides indiens remontent des cols de montagne avec David Thompson ou Jimmy Simpson, en portant de lourdes charges sur des sangles.

Like most municipalities in Canada, we are grappling with how to prevent and prepare for the impacts of a warming world. As a tourism town nestled in a national park, Banff already faces several challenges – affordable housing, cost of living, and vehicle congestion, to name a few – but climate change is the most imminent one because it can cause dramatic change to our lives and livelihoods.
