Milbanke Sound Group

The Milbanke Sound Group is a collection of five basaltic volcanoes distributed across four small islands within the Kitimat Ranges of the Coast Mountains. The islands display dark volcanic rock formations with steep slopes, and the tallest peak rises approximately 335 meters above the water.

These volcanoes formed after the last Ice Age, roughly 10,000 years ago, through volcanic activity in the region. Their minimal erosion patterns indicate their relatively recent geological creation.

The volcanic islands hold importance for Indigenous communities who have maintained connections with these lands through generations of resource gathering.

Reaching the islands requires boat or helicopter transport, so advance planning is necessary before visiting. Working with local guides is recommended since infrastructure is limited and water conditions can be unpredictable.

The tallest peak, known as Helmet Peak, displays steep sides made of welded volcanic blocks and holds significant deposits of basaltic tuff breccia. These special rock formations are uncommon and reveal the intense volcanic activity that shaped this landscape.
