This towering mass of water and ice shook the ground as it thundered towards the Pacific Ocean, stripping away soils and cutting deep canyons in the bedrock. With flood waters roaring across the landscape at 65 miles per hour, the lake would have drained in as little as 48 hours.

The Survey today Introduction Sir William Logan A comprehensive knowledge of the geoscience of the Canadian landmass and its offshore is fundamental to economic development, public safety, environmental protection and national sovereignty. To acquire, interpret and make available that information to all Canadians is the mission of the Geological Survey of Canada. It is an immense and challenging task that encompasses four billion years of geological history. It takes the staff of the Survey to the farthest frontiers of our huge country and keeps them at the forefront of scientific knowledge and technology.
