erosion control at Cha-usu-yama, southwest face

Middle March view of the sophisticated system of drain tubes, soil anchors, cement skin with ribbed structural reinforcement, and strong base to firmly hold the slope from succumbing to gravity, the force of water and the freeze-thaw cycle each year. Compare this bare surface to the middle September picture of the surface to the right of this frame, after a spring and summer of growth, www.flickr.com/photos/anthroview/37230806926
