Sudbury lies north of Georgian Bay and west of Lake Nipissing, where the two branches of the TransCanada Highway diverge. Geologists believe a huge meteorite struck the Sudbury area 2 billion years ago, which accounts for its mineral-rich basin. Once a lumber center, the community is now a world-known center for mining, smelting, refining, and geological science. The region around Sudbury includes 157 lakes and 1,200km (700mi) of snowmobile trails. The area is popular for swimming and fishing for walleye, muskellunge, northern pike, and bass. Sudbury hosts a number of live theater and musical events, as well as the Garlic Festival, the Blueberry Festival, and the Cinefest International Film Festival.
