Diamond Mountain Golf Course

Diamond Mountain Golf Course sits in Susanville, the county seat of Lassen County in the high desert plateau of northeastern California at roughly 4,200 feet of elevation. Susanville is positioned in the Susan River valley where the Sierra Nevada meets the Great Basin, in a region that shares characteristics with both the forested mountain terrain of the Sierra and the sagebrush plateau of the Nevada borderlands. Lassen County is one of the largest and most sparsely populated counties in California, and Susanville functions as the isolated commercial and governmental hub for this high-elevation northeastern corner of the state.
