[Geysers] Cones

[Eric Hatfield]

I recognize the sentiment, but I'm glad to see peoples' recognition that there are actually lots of cones all over the place.

Riverside I don't think has been mentioned yet.  Huge cone (really 2 of them.)

Cliff Geyser extends the definition--really big formation there.

How about the huge "cones" at Sentinal Meadows?

How about many examples of extinct cones to be found?  The Ruin.  That big cone remnant in site of the OF overpass, uphill from Black Sand.  Lots of examples.

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?
