Crow Lagoon is a fascinating place in British Columbia, Canada. It's a type of volcano, but not one that looks like a tall mountain. Scientists have found layers of thick, dark rock pieces called tephra here. This tephra is made of a rock called basalt, and it tells us about past eruptions. These eruptions happened during the Holocene period, which is the last 11,700 years.

What is Crow Lagoon?
Crow Lagoon is a special kind of volcano called a pyroclastic cone. This means it's a cone-shaped hill built up from volcanic ash and rock fragments. These fragments are thrown out during explosive eruptions. It's located north of Prince Rupert in British Columbia. Even though it's not a famous tall peak, it's an important part of Canada's volcanic history.
How Big is Crow Lagoon?
Crow Lagoon reaches an elevation of 335 meters (about 1,099 feet) above sea level. This isn't super tall compared to some mountains. However, it's a significant height for a volcanic cone. Its size shows the power of the eruptions that built it up over time.
Is Crow Lagoon Active?
The last time Crow Lagoon erupted is not known for sure. However, scientists are interested in it because of recent activity. It is one of the top 10 volcanoes in Canada that has shown recent seismic activity. Seismic activity means there have been small earthquakes or tremors. These tremors can sometimes be a sign that a volcano is still active deep underground.
Canada's Volcanic Hotspots
Crow Lagoon is not the only volcano in Canada that has shown recent seismic activity. There are several others that scientists watch closely. These volcanoes are located in different parts of Canada. They remind us that Canada has a rich volcanic past, and some areas are still active.
Here are some of the other volcanoes in Canada with recent seismic activity:
- Castle Rock
- Mount Edziza volcanic complex
- Mount Cayley
- Hoodoo Mountain
- The Volcano
- Mount Silverthrone
- Mount Meager massif
- Wells Gray-Clearwater volcanic field
- Mount Garibaldi
Studying these volcanoes helps scientists understand how the Earth works. It also helps them predict future volcanic events.
