New Quebec Orogen

Swirling folds of basaltic rock can be seen in the New Quebec Orogen, a large geologic belt in northeastern Canada. This area, also known as the Labrador Trough, covers an area of about 98,000 square miles (254,000 square km) and was formed some 2.17 billion years ago as molten rock erupted from rifts in the Earth’s crust flooded the landscape with basalt. The cliff face of each flow or “step” in this formation stands between 160 and 230 feet (50-70 m) tall.
