This map is from Derek Hayes' 2002 Historical Atlas of Canada, the most beautiful of all the historical atlas projects. The image is linked to Google books where one can see just how beautiful.
One of the conditions of the colony of British Columbia joining Canada in 1871 was the building of an overland link from BC to the rest of Canada. This was the commission given to the CPR and completed in 1884. Is BC a different world than the rest of Canada? They certainly think so.
This map, drawn in the 1870s when much of BC was simply unknown to surveyors and engineers, shows just how much of a conundrum this territory must have seemed. After sailing breezily through the flat land of the prairies where nothing can be hidden from view suddenly there is the wall of the Rockies. Even today, on the much improved Trans-Canada, one cannot get through BC quickly, and the older Highway 3 through the Crows Nest is very convoluted. However, such roads keep one more alert than driving through southern Saskatchewan in a 500 mile straight line.
I like this map for the dismay it seems to exude. BC was going to be a hard project.
