So you have maybe an hour before the fire overruns your location. There is no escape, no large cave or body of water, and you are in mixed forest with small creeks and meadows, various small elevation changes, some rocks.

What is your best shot at survival? Given what you normally carry for camping and hiking, what is the best type of shelter you can build? How can you best provide for thermal protection and some kind of air supply protection? Or is it hopeless?

Edit: is there some other gear to consider carrying in fire season that might give you a better shot?
