Here is a good example of the type of fog you see on Mark Twains favorite
river:

http://away.com/gifs/states/mn/fall_missriver.jpg

Anyone know what type of fog this is? And how it is formed?

Notice how calm it is? makes it thick as can be
Notice how flat the water is? great for a crystal clear radar picture
Notice how low it is? Lots of sunlight makes it very bright-snowblinds ya
Notice the steep banks? Makes a easy-to-learn radar picture.


How many other types of fog exist?

Would you be scared to navigate in this fog?

It looks like a blanket of fog in chilly air over warm water, I forget the
official name for it. And if it is in St Paul Minn, it's well above Mark
Twain country IIRC.

If it was on a river with current, yes.

That's not what MC said...

Ain't it funny how you and I (and probably a quite a few others around here) could deduce the conditions but only Navvie knows it's proper taxonomy (or is it orthography).
