Mount St. Helens


Recommended Posts

Here is something not many of us get to see, unless

you live near there - Mt. St. Helens at sunrise. 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. Picture

Re: Mount St. Helens

If you research that photo source I bet you'll find that is Mt Rainier. The three knobs give it away and the 'cap clouds' are a common occurance there - Still a great photo.
