A succession of Eutrustox‐Eutrorthox‐Gibbsiorthox‐Gibbsihumox occurring in northeastern Kauai, Hawaii, is shown to be a climosequence. These soils developed synchronously on basic lavas forming one geomorphic surface of Pleistocene age. Ultisols found along the knickpoint of this surface to recent erosion surfaces are the result of soil creep. The mechanisms of clay mobilization by soil shear caused by creep are discussed.
