(Alaska.) Each of the National Forests is under the direct supervision of a forest supervisor and is split up into from 5 to 10 or more ranger districts.

Each ranger district is in charge of a forest ranger who has an area of from 100,000 to 200,000 acres in his charge.
The National Forests are, for the most part, located in the mountainous region of the West, with small scattered areas in the Lake States, and the White Mountains, Southern Appalachians and Ozarks of the Eastern and Southern States.

Many of them are a wilderness of dense timber.

It is a huge task to protect these forests against the ravages of fire.

Fire fighting takes precedence over all other work in the National Forests.
