Iskut-Unuk River Cones

The Iskut-Unuk River Cones are a group of eight small basaltic centres at the southern end of the Northern Cordilleran Volcanic Province in the Boundary Ranges of the Coast Mountains, in western North America. The lava flows date back 70,000 years, but the subaerial vents produced cinder cones and lava flows that were probably all active between about 9,000 and a few hundred years ago. The last lava flows were erupted from The Volcano about 150 years ago. Iskut Canyon Cone produced at least 10 thick lava flows which initially dammed the Iskut River.

Volcanoes

The name of these in the Tlingit language is Seikhulé, referring to the mountains not being flooded during Aangalakhú (the Great Flood) and they were one of the high peaks used as a refuge during that time.
