Round Mountain is a mountain located in the northwestern part of British Columbia, Canada. It stands about 22 kilometers (14 miles) east of a place called Dease Lake.
This mountain is more than just a regular peak. It's actually a special type of landform created by volcanic activity!

What is Round Mountain?
Round Mountain is a volcanic feature. This means it was formed by volcanoes, but it's not a typical cone-shaped volcano you might imagine. Instead, it's a type of mountain that grew from volcanic eruptions.
A Subglacial Mound
Round Mountain is known as a subglacial mound. Imagine a volcano erupting under a thick sheet of ice or a glacier! When lava erupts under ice, it cools very quickly. This fast cooling creates unique shapes and structures. Round Mountain is an example of this cool process.
How it Formed
The lava from the eruption pushed up the ice above it. As the lava cooled, it created the mound we see today. This happened a very long time ago, during a period when much of Canada was covered in ice.
When Did it Form?
Round Mountain formed during the Pleistocene epoch. This was a geological time period that started about 2.6 million years ago and ended about 11,700 years ago.
The Pleistocene Epoch
The Pleistocene is often called the "Ice Age" because huge glaciers covered large parts of the Earth. Many animals, like woolly mammoths and saber-toothed cats, lived during this time. Round Mountain's formation fits right into this icy history!
Part of a Volcanic Region
Round Mountain is part of a larger area called the Northern Cordilleran Volcanic Province. This is a big region in western Canada and Alaska where many volcanoes have been active over millions of years. It's like a chain of volcanic spots!
- This province includes many different types of volcanoes.
- Some are still active, while others, like Round Mountain, are ancient.
- Studying these features helps scientists understand Earth's history.
