That has to be one of the most terrifying things I've ever seen I've read stories about the fires like this (the Carr Fire for example), but this is so close to the "front", it really gives you a true perspective of how monstrous these fires can be. The hotshots and smokejumpers that handle things like this are the most unsung heroes in the world. The next time you see a firefighter, make sure to thank him; and his brave brothers & sisters for putting their lives on the line everyday.
