Worried About the Tunnel Fire

Wow, Sunset Crater was completely burned over. Flagstaff forests are pretty dry, but despite their scattered nature, they have lots of underbrush:

(CNN) Hundreds of homes near Flagstaff, Arizona, have been evacuated as a fast-moving wildfire threatened hundreds of structures Wednesday after destroying at least two dozen buildings, officials said. 

The Tunnel Fire in northern Arizona's Coconino County had burned more than 19,700 acres as of Wednesday afternoon, according to InciWeb, a US clearinghouse for wildfire information. It was first reported Sunday afternoon.

The fire, about 14 miles northeast of Flagstaff, was rapidly moving to the northeast, pushed by significant winds, officials said. It had no containment as of Wednesday afternoon.

"I cannot stress enough how rapidly this fire is moving," fire management officer True Brown said.
