The Imuruk Lake volcanic field is a special area in western Alaska, United States. It's not just one big volcano, but a collection of many smaller volcanoes and lava flows. This interesting place is found near Imuruk Lake in the Bering Land Bridge National Preserve, which is in the middle of the Seward Peninsula. It's also considered part of a larger group of volcanoes called the Bering Sea Volcanic Province.

What is a Volcanic Field?
You might imagine a volcano as a single, cone-shaped mountain that erupts. But a volcanic field is different! It's a large area of land where many smaller volcanoes have erupted over a long time. Think of it like a giant playground for volcanoes, with lots of different vents and cracks in the Earth's surface where magma can come out.
How is it Different from a Single Volcano?
Instead of one main vent, a volcanic field has many places where lava can flow out. These can be small cones, craters, or even just cracks in the ground. Over thousands of years, these eruptions build up a wide area of volcanic rock.
Where is the Imuruk Lake Volcanic Field Located?
The Imuruk Lake volcanic field is in a remote and beautiful part of Alaska. It sits on the Seward Peninsula, which is a large piece of land that sticks out into the Bering Sea. This area is part of the Bering Land Bridge National Preserve.
The Bering Land Bridge National Preserve
The Bering Land Bridge National Preserve is a very important place. It's known for its amazing wildlife and its history. Thousands of years ago, during the Ice Age, a land bridge connected Asia and North America right here. This allowed animals and even early humans to cross between the continents. The volcanic field adds to the unique landscape of this preserve.
When Did Imuruk Lake Last Erupt?
Scientists believe the last time there was volcanic activity at the Imuruk Lake volcanic field was around 300 CE. The "CE" stands for "Common Era," which is a way to measure years, similar to AD.
What Does "300 CE (?)" Mean?
The question mark next to "300 CE" means that scientists are not entirely sure about the exact date. It's an estimate based on studying the rocks and lava flows. Volcanic fields can be active for a very long time, with eruptions happening every few hundred or even thousands of years. While it hasn't erupted recently, it's still a fascinating place to study Earth's powerful forces.
