[Geysers] Cones

[Paul Strasser]

I would include Daisy (it's not "insubstantial") Bijou and Turtle, and one
of those geysers up near Avoca (forgive me - I don't recall which one).  

I don't consider Vent as having a cone.  It's a slit in the side of Turban,
and there is essentially zero sinter accumulation around its orifice that
indicates any sort of buildup of material.  

Turban is interesting.  It's a raised mound, that's for sure, but its
topography probably wouldn't be under the umbrella of "cone" shapes.

And I can think of a few out in Sentinel Meadows.

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?
