The Iskut-Unuk River Cones are a group of eight small basaltic centers at the southern end of the Northern Cordilleran Volcanic Province. 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 9000 and a few hundred years ago. The last lava flows were erupted from Lava Fork Valley, about 150 years ago. Iskut Canyon Cone produced at least 10 thick lava flows which initially dammed the Iskut River.
