Mount Edziza is more than just a mountain; it is a geological archive spanning millions of years. Located in the remote wilderness of British Columbia, this volcanic complex has shaped the survival of the Tahltan people and remains a site of immense scientific interest.

A Million-Year Story

Mount Edziza’s history is written in layers of lava and ash. It is one of Canada’s most complex volcanoes, with a history of eruptions that produced vast quantities of high-quality obsidian. This volcanic glass was the steel of the ancient world.

The Obsidian Trade

For thousands of years, the obsidian from Edziza was harvested by the Tahltan people. It was used to craft razor-sharp tools and weapons, which were traded across vast distances—reaching as far as Alaska and Alberta.

• Sacred Grounds: We explore the harvesting grounds with permission from Tahltan elders, highlighting the deep cultural connection to the land.
• Mary Weget: A Tahltan artisan demonstrates the ancient skill of obsidian tool-making, keeping the tradition alive.

Modern Monitoring and Risk

Though currently “sleeping,” Mount Edziza is watched closely by scientists 24/7. Its proximity to major air routes means that any future eruption could have significant impacts.
