The Hope Ranch Smoker Continues

Thank you all for your thoughtful comments. Here is a map of the location of the Hope Ranch Shale Fire: https://www.google.com/maps/@34.4100829,-119.7670342,56m/data=!3m1!1e3 . It would seem to me that an effective method of smothering the burning petroleum would be to enlist one of the fire suppression engines from the airport to pump foam into the opening in the cliff from which the smoke emanates. That's probably a less expensive approach than helo water drops.
