Ontario Trans-Canada Highway Route: along Highway #17 between Mattawa and Ottawa, Ontario
Here is the itinerary for the 304 km along Highway #17 between Mattawa and Ottawa
From Mattawa south, the Ottawa Valley is a generally wide and fertile tongue into the Canadian Shield. The Ottawa River draws water from such a large area, there are actually two spring flood seasons, the first for meltwaters from southern Ontario, and the second (just over a month later) for meltwaters from northern Quebec.
Just east of Rolphton is the Des Joachims Dam, the larges hydro-electric generating station along the Ottawa River. Driftwood Provincial Park, 8 km upstream on Holden Lake has rock outcrops with gneiss and granite, and lots of small creatures like rabbits and porcupines. At Pembroke you will find Canada's first hydro-electric dam, still operating and generating since 1889, and the city is decorated with murals showcasing the city's history.
Between Chalk River, home of Canada's Atomic Energy Research Facility, and Petawawa the highway passes through a Sand Plain zone, formed by an ancient river delta. The vegetation here is mostly jack pine with blueberry bushes, about the same as on the sandy Cape Cod seashore of Massachusetts. The land transitions into the training area for CFB (Canada Forces Base) Petawawa, which is why the telephone poles are so low to the ground alongside the highway.
Around Cobden, the valley widens significantly, and the wide fertile valleys have been farmed since the early 1800s. There is a rough Morraine zone around Renfrew, with rocks and ridges left behind from the last Ice Age. Around Arnprior, the good farmland returns with rich soils around the Mississippi and Madawaska Rivers. These rivers were the heart of early Ottawa Valley lumber industry, which in the 1840s led to the establishment of Ottawa and Hull (now Gatineau).
Between just west of Kanata, the highway passes through a Limestone Ridge zone, where there are very shallow soils on top of exposed limestone from 200-450 million years ago. These will be exposed at rock cuts for roadways. When you hit Kanata, this is contrasted with all the glass-covered office towers for the many high-tech companies headquartered there. This community has grown up from basically bare pasture since the 1970s.
