Ultramafic rocks are extensive in the Klamath Mountains of California and Oregon and there is a great diversity of climate, soils, and vegetation. Soils were sampled and vegetation described over serpentinized peridotite at 16 low altitude, well drained sites from arid to humid parts of the Mountains. The soils are dry Mollisols and Alfisols, moist Alfisols, Ultisols, and a moist Mollisol. Major clay minerals are smectite in dry soils to goethite in moist, weathered soils. Some serpentine soils with very high "free" iron contents indicate net positive charge in the soils. Net positive charges in soils lacking tephra are unique for nontropical soils. Plant communities on the cooler remainder of the transect, near 42°N latitude, from arid to humid, were sagebrush steppe, open conifer forest with shrubs and grass, semidense conifer forest with shrubs, and dense conifer forest
