[Geysers] 1986 Fantail video

[JEFFREY CROSS]

John Warnock asks an interesting question--what about the Pink Cone Group?  Many of the geysers there erupt to about 25 feet high.  Some other places where features share a common characteristic:

At Midway Geyser Basin, many vents are large and deep.

In the Dolina Geizerov, many geysers had brief eruptions on short intervals.

At Shoshone Geyser Basin, the largest geysers with a long history of activity (Union, Minute Man, Frill, and Knobby) erupt(ed) in series.

In the Lower Geyser Basin, nearly every geyser erupts from a pool, whereas in the Upper Geyser Basin, many geysers erupt from cones.

Someone once characterized geyser activity in the Kaleidoscope Group as "huge, brief, and angled."  Many of the geysers there also erupt in series.

I suspect that there are real reasons for these observations.  Large eruptions require deep plumbing systems, and long eruptions require large reservoirs.  One can extrapolate from this that, perhaps, all the reservoirs in the Pink Cone Group lie at the same depth beneath the surface; that the geysers in Dolina Geizerov all erupt from small rock-bound reservoirs while in Yellowstone, geysers erupt from large reservoirs in cemented glacial deposits and valley fill.  Perhaps, also, the hilly terrain in the Upper Geyser Basin resulted in the formation of cones, while the flat topography of the Lower Geyser Basin resulted in the formation of pools.  Perhaps the stratigraphy at Shoshone Geyser Basin and the Kaleidoscope Group favors plumbing systems that give eruptions in series.

Thanks Karl;

As I watched it, it reminded me of Seismics' eruptions in the mid 1960's.  But then again I was a mere lad at the time.  It did make me ponder, however, if those similarities might have something to do with something going on underground in that area.  Probably not, but still something for sharper minds than mine to contemplate.  Can anyone think of other situations like that where a group (even 2) of  geysers have similar looking eruptions in reasonably close proximity to one another? ( ie: Fountain and Morning, Daisy and Splendid) If so, why are these eruptions similar in form?  It is way too early in the morning for me to be thinking like this.  Just something else for you all to ponder.

That was wonderful, Karl...keep 'em coming. Probably the closest I will ever get to seeing Fantail. But then again, I said the same thing years ago about Cascade, and Silex, and Butterfly Spring, and even Giant once upon a time. So who knows?

I'm in the process at attempting to transfer my parents' (Warren and Pat Hoppe) old Super 8 film movies to digital video formats.  While the process is still in "development", I've posted my first attempt on YouTube.  Fantail Geyser from 1986.  Others will follow over time.
