Churchill Craton

The Churchill Craton is a very old piece of Earth's crust that forms the northwest part of the Canadian Shield. It stretches from southern Saskatchewan and Alberta all the way up to northern Nunavut. This area is made up of rocks that are billions of years old, showing how Earth looked a very long time ago.

One special part of the Churchill Craton is called the Western Churchill province. It dates back to a time known as the Archean, about 1.83 billion years ago. This area helps scientists understand how the Earth's continents moved and changed over millions and millions of years. The Western Churchill province shows a big shift in how this part of Earth behaved, making it very important for learning about our planet's history.
