Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Iskut-Unuk River Cones
Shallow ponds dot the surface of valley-filling lava flows of the Iskut-Unuk volcanic field. The flows traveled south 5 km where they crossed the border into Alaska and dammed the Blue River, forming several small lakes and traveling a total of approximately 22 km. The Iskut-Unuk River Cone Group consists of eight small basaltic centers at the southern end of the Stikine volcanic belt that range in age from about 70,000 to only a few hundred years old and form one of the youngest volcanic fields in Canada.
