Truman from portions of Klamath, Siskiyou and Trinity National Forests. Its over one million acres of land contain a variety of ecosystems and 137,000 acres of old growth forest. It lies in parts of four counties; in descending order of forestland area they are Del Norte, Humboldt, Trinity, and Siskiyou counties.
