Licancabur Volcano (5916 m) is a mountain whose shape is similar to Mt.Fuji. At around 8 oclock in the morning, I found the volcano wearing a hat of lenticular clouds. The cloud didnt have perfect lenticular shape, but it can be called as lenticular cloud. It was very interesting to watch the cloud changing its shape, extending and breaking the right side of the lens (leeward) like glutinous rice cake. As lenticular clouds are supposed to be a precursor of strong wind, a dust storm began to blow in the afternoon as expected [texts provided by Masato Ishiguro].
