Abstract: Airborne laser scanning was carried out on Mt. Niseko-Annupuri in Hokkaido, Japan, during the winter season to obtain detailed snow cover distributions, including snow cornices and snowdrifts. Close observation of the snow cornice distribution revealed that there were two distinct areas on a continuous ridge where snow cornices were developed and non-developed. In order to understand the differences in snow cornice development, the topographic conditions near the ridges were analysed. The results showed that the slope angle was higher on the windward side of the ridge where snow cornices were not developed. This suggests that the wind flow may change in a way that makes it difficult for snow cornices to develop.
