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. 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 The Volcano about 150 years ago. Iskut Canyon Cone produced at least 10 thick lava flows which initially dammed the Iskut River.

Famous quotes containing the words cones and/or river:

    ...there was the annual Fourth of July picketing at Independence Hall in Philadelphia. ...I thought it was ridiculous to have to go there in a skirt. But I did it anyway because it was something that might possibly have an effect. I remember walking around in my little white blouse and skirt and tourists standing there eating their ice cream cones and watching us like the zoo had opened.
    Martha Shelley, U.S. author and social activist. As quoted in Making History, part 3, by Eric Marcus (1992)

    Up a lazy river by the old mill run, that lazy, lazy river in the noonday sun.
    Sidney Arodin, U.S. songwriter. “Lazy River,” Peer International Corp. (1931)
