[Geysers] Cones

[TSBryan at aol.com]

Define "cone" -- how tall does it need to be to qualify? Depending on this,  
you might have missed quite a few ... including at Norris.

How many  substantial free-standing geyserite cones exist in Yellowstone?

Upper  Geyser Basin:

Old  Faithful
Beehive
Lion
Castle
Giant
Grotto
Rocket
Mortar

Lower  Geyser Basin:

White Dome
Pink Cone
Jet
Clepsydra

Lone  Star Geyser Basin:

Lone Star Geyser

Shoshone Geyser  Basin:

Union Geyser
Minute Man Geyser

Heart Lake Geyser  Basin:

Puffing Spring

Are there really none at Midway, Norris,  Gibbon or West Thumb?

It is interesting to note that of the cones I  have listed (16), 8 of them 
(50%) are in the Upper Geyser Basin.

One  might also ask how to define a "cone."  I am listing only those cones  
that have an arresting appearance.

Low, mound-shaped masses of sinter,  like those around Bulger Geyser, seem 
very different, almost as if they formed  through a different process.  
Therefore I did not include them in the  list.  It would appear that cones are fairly 
rare.

Any  thoughts?
