Thompson Peak (Maidu : Widojkym Jamanim) is the second highest peak in the Diamond Mountains of the Sierra Nevada. Rising to 7,795 feet, it sits on the border of Lassen and Plumas Counties, California, in the United States.[4]
It was named after Manly Thompson, who built one of the first cabins in the area in 1875 near the base of the mountain.[5]
A two-story lookout was completed in 1932 and is still actively used by the Plumas National Forest.[6][7]
A 37 acres site was used by the US Air Force as an Aircraft Control and Warning site from 1958 to 1970.[8]
