[Geysers] Yellowstone Whispers

[Steve Krause]

My wife had a slightly different analogy after reading the descriptions. 
Perhaps it's something analagous to blowing across the lip of a bottle - a 
higher altitude wind with a well defined boundary layer, and the caldera 
itself forming a resonance chamber for it to "blow across". Alternately: 
breezes creating a brief resonance with the surface of the Lake?

Speculation about something as evocative and unusual as this is fun! You'll 
never know the answer, and somehow I think knowing the answer would take 
half the enjoyment out of it. Like knowing all the details of when a geyser 
is going to erupt - takes all the challenge and mystery out of it!
