By 1956, the year this geological map was published, the Geological Survey of Canada was already well over a century old — founded in 1842, it's the country's oldest scientific agency, tasked with charting the rock formations underlying a nation that stretches from the Atlantic to the Pacific to the Arctic. The map catalogs that geology across Canada's vast shield country, the Rockies, and the plains in between, from an era when the federal government was pushing new infrastructure — including the Trans-Canada Highway, then under construction — deeper into the country's interior. Muir Way georeferenced the original 1956 survey and added shaded relief using modern digital elevation data, so the Canadian Shield, the Rocky Mountains, and the interior plains read with real topographic depth. It's printed flat on fine art paper — the 3D look comes from the shading alone. Note on legibility: because of the map's small original typeface and age, some text is faint, and labels beneath the darkest relief shading aren't legible. We suggest the largest available size for the clearest read, though some darker areas may still obscure fine print.
