Saskatoon retains a distinctly Western air, with cowboys and horse trailers as numerous as flame-haired University of Saskatchewan students on its downtown streets. But the university provides Saskatoon with its economic clout, as it is one of North America's top bioscience research centers. This seemingly remote city on the edge of Canadian prairies is at the center of today's world of agribusiness. In addition, much of the city's recent wealth has come from the surrounding mining region that yields potash, uranium, petroleum, gas, and gold; nearby Key Lake is the world's most productive uranium mine.Scenically, Saskatoon possesses some distinct natural advantages. The South Saskatchewan River cuts a swath through the city. Spanned by several graceful bridges, its park-lined banks are great for strolling, biking, and jogging.
