Snow Cloud


1.   At Shibu Pass of 2152 meters of altitude in Nagano Prefecture in Japan   (in Oct. 23, 1994)

    When I went towards the Kusatsu hot spring through the Shibu Pass (on National Highway of No. 292, altitude 2152 meters) in Oct. 23, 1994, suddenly winter monsoon began to blow and it became violent wind and snow.   Snow was piled up and land became to be covered about five centimeters of snow in a short period of time.
    No way, I did not think that I met to snow at this time.   Although the tire chain was in equipped, the tire of my car remained of normal.   So, for fear of getting stuck in the snow and in a hurry to escape from the snowstorm, there was no chance to shoot the state of the snow cover.
   When I drove the car until Shibu Pass in a hurry, sunny had come out at Shibu Pass.   However, I still saw snow cloud hanging over Mt. Kusatsu-Shirane (By the way, water vapor eruption occurred in Jan. 23, 2018.    However, it got quiet in several hours after.).     Snow cloud seen in Oct. 23, 1994 is shown in the followings.

And when the sun hits the rain, a rainbow is formed.

In addition, since the TV screen was once shot with a digital camera,
The furniture in the room is faintly reflected.
