A belt of snow-spotted lava beds stretches across 568,342 acres (230,000 hectares) of Mount Edziza Provincial Park in northwest British Columbia. The park is a spectacular volcanic wilderness of lava flows, basalt plateaus, cinder fields and cones formed from eruptions and basalt flows that occurred between 10,000 and 4 million years ago.
