• Development of multiple ridges in the southern frank of Gurjia Himal, mid-western Nepal, was studied (Fig. 1). Geomorphologic feature, a cross section (Fig. 2) and a plane figure of the multiple ridges (Plate 1) at Loc. 1, shows bulging of a gentle crest slope down to the east and subsequent subsidence of a ridge top occurred. Widening of joints, of which strikes are concordant with trends of the multiple ridges (Fig. 3), extensively occur just below the ridges (Plate 2). Open cracks in joint systems were filled with injected clay (Plate 3). Deformation of the gentle crest slope down to the east and subsequent subsidence of the ridge were undertaken by progressive widening of joint system in bed rock of the ridge as a whole due to self-gravity, considering above mentioned geomorpho-geological features.
