Abstract
A large solifluction lobe has been discovered on the windblown slope to the northwest of Mt. Yukikura, Hida Mountains (Fig. 1 and Photo 1). It is raised, relatively flat-topped, tongue-shaped accumulation of angular rock debris, and it is about 70 meters long, 40 meters wide and 2.5 meters thick at the toe. The peripheral scarplet of the lobe is covered with Pinus pumila community, and the top surface, gently (about 15 degrees) declining westwards, is bare and stony. The lobe has originated from the back periglacial debrismantled slope, pushed on downwards, and ridden onto the front gentle slope which is occupied by snow-patch meadow of Carex blepharicarpa·Fauna crista-galli community.
