Ridge-top Gentle Slope east of Mt. Kanmuriyama.
    Many ridge-top gentle slopes occur in the Ryohaku Mountains, central Honshu. This photograph shows one of these gentle slopes "Kanmuridaira", just east of the Mt. Kanmuriyama, 1,256 m height. On this gentle slope shallow depression and up slope-facing scarp can be recognized. These gentle slopes are thought to be made up of debris which fills up depressions formed by rock gliding of basement sedimentary rocks, mainly Jurassic accretinary complex. However, the detail of the process and age of their formation are still remained unsolved.
