Sawtooth National Forest is in Idaho (~96%) and Utah (4%)[citation needed] was protected in 1905 by U.S. President Theodore Roosevelt as the Sawtooth Forest Reserve. Today the forest administers over 2.1 million acres (8,500 km?) of some of the most remote forestland in the lower 48 states, and there are over 1,000 lakes and 3,000 miles (4,830 km) of rivers and streams. The Sawtooth National Recreation Area of the forest is "in the heart of Idaho".[1]

In descending order of forestland area it is located in Blaine, Cassia, Camas, Custer, Elmore, Twin Falls, Box Elder, Power, and Oneida counties. Forest headquarters are in Twin Falls, Idaho. There are local ranger district offices in Burley, Fairfield, Ketchum, and Stanley.[2]
