Abstract
A field research work was carried out to investigate physical properties of mountain snow forming firn, located near the top of valley of Mt. Hakusan, Ishikawa Prefecture, in this summer.
The firn size was about 120 × 100 (m2) and 6-10 (m) in depth at the center.
Summarizing results of observations, the density of the firn was about 0.6-0.7 (g·cm-3), water content was about 10 (%) and hardness was 5 × 103-3 × 104 (g·cm-2).
