休眠中的Mt. St. Helen　活火山

Mt. St.. Helens continues to spew ash, while it is forming a lava dome in the crater and still having minor tremors.

Here in this sunrise shot, she appears to be blowing smoke rings (and anything so benign is welcomed, given recent history).

What forms the "smoke rings" is the air flowing over the mountain getting pushed up higher as it goes up and over the top. The moisture content and initial temperature are just right so that the moisture

condenses from a vapor to small particles at the higher altitude. When the moving air moves past the peak and comes down again, the particles evaporate back to an invisible vapor.

The two "pancakes" describe that there are two layers of air for which this is happening, thus making this awesome picture possible.

莲花啊，你太惜墨如金了，请多给我们做些介绍吧！是你去了那里么？那里每天都有这样的云彩么？

太美了！

太美了，我喜欢山，每次爬山神圣感油然而生，顿觉自己的渺小。

Mt. St. Helen is in Washington state of USA.   I found a link for a brief introduction as follows
