The Pyramid

The Pyramid is a prominent conical lava dome on the northeastern flank of Mount Edziza in northwestern British Columbia, within a vast volcanic complex formed over the last 7.5 million years. Rising 2,199 metres, it formed about 1.1 million years ago from highly viscous trachyte that piled up into a steep dome rather than flowing outward. Slabs shed from its hot surface created a ring of oxidized debris and active talus, while nearby gravel deposits preserve fragments of that apron. The mountain also has archaeological importance: its obsidian outcrops, especially Pyramid High, supplied volcanic glass used by Indigenous peoples before contact and traced to sites beyond Tahltan territory.
