Science North

Science North opened in 1984 in two snowflake-shaped buildings joined by a rock tunnel blasted through a billion-year-old fault, so visitors walk through the geology on the way in. Sudbury sits in a crater created by a meteorite impact around 1.85 billion years ago, which concentrated the nickel and copper that built the city, and the centre works that story hard. Its sister site, Dynamic Earth, includes an underground mine tour and stands beside the Big Nickel, a nine-metre stainless steel replica of a 1951 Canadian five-cent piece erected in 1964 and now the city's emblem.

What you actually see

• The rock tunnel - a passage blasted through a billion-year-old fault line.
• The Big Nickel - a nine-metre replica coin outside Dynamic Earth.
• The underground mine tour - a descent into a demonstration mine.
• The impact crater story - the meteorite that created Sudbury's ore body.

When to go

Year-round; both sites open daily in summer with reduced days in winter. Dynamic Earth's mine tour runs on a schedule. The two sites are several kilometres apart.

Honest expectations

Science North and Dynamic Earth are separate locations needing a car or bus between them. The mine tour is cold and involves a cage descent. Content is aimed largely at families.
