[Geysers] Spiteful's Sput

David's discussion is spot-on.  They are on and off for long periods of
time, sometimes months or more, and seem to be little more than general
manifestations of water and energy in the system .  for a fee years in the
80s the Tile Vent would splash water and steam in a vigorous manner during a
major eruption of F&M.


The first time I saw them was in 78, and I wondered if they were the cause
of F&M's dormancy.  This was a time when the "consensus" was that Spiteful
and F&M Were strongly connect, that F&M only erupted when Spiteful was empty
(post eruption) and not flowing into the east vent.


It is interesting that David mentioned Daisy's cone vents.  I always said
that the Spiteful sputs were akin to the bubblers in the flats south so
Splendid.'  Same area, same concept.

   There are actually at least four more-or-less related vents above
Spiteful, but two of them are usually buried.


   The first is the familiar "Spiteful's Sput," a slit-like vent located in
Spiteful's crater on a shelf right at or just above the water line, that
ranges from continuous blurbling to large, angled jets that land well clear
of the crater.  It's activity is pretty consistent and continuous any given
year--when it's active, the only times it stops are after euptions of
Spiteful (stops entirely) or Fan and Mortar (sometimes stops, sometimes
slows down to strong overflow, sometimes keeps going, possibly related to).


   To the left of and above the main sput (viewed from the old road),
there's a crack that more or less lines up with the fissue Spiteful and
Fan's vents are on.  This crack is also sometimes active as a spouter,
albeit a much smaller one.  When active, water is visible splashing in and
just above the crack.  It's visible, but not erupting, just below and left
of center in this photo:


   Next, just up from the crack and basically in line with it, there's a
vent that is almost always buried.  It was cleared in the mid 1990s by NPS
volunteers and took over much of the function of the main sput.  The crack
vent was active along with it, and as I recall, the main sput was reduced to
a strong, bulging overflow.  This vent was reburied over the course of a
year or two and to my knowledge, no effort has been made to clear it since.


   The last one is probably not directly related to the other three.


   It's well known that, when the road was built through the Upper Geyser
Basin, a spring/geyser above Spiteful at the edge of the road was capped
with stone and concrete and its output diverted through a tile-lined culvert
to an outlet downslope from Spiteful.  The culvert was known to discharge a
flood of output during eruptions of Fan and Mortar in the '80s and '90s, so
it was often referred to as Fan's "Tile Vent."  One summer in the late
1990s, a spot in the gravel in front of the concrete cap started steaming,
sputtering, and periodically filling with water.  We all assumed at the time
that it was a break in the pipe or some other expression of the buried
spring.  The activity did not persist.


   As for whether they're separate geysers...  I'd say no, not any more that
the cone sputterers on Daisy are separate geysers.  When Spiteful is full,
the sput is in eruption--from whichever vent is dominant.  When Spiteful
drains after an eruption, the sput quits.  It's a high-water-level vent of
Spiteful that functions as a perpetual spouter when active.

A question for all:

Is the small vent at the uphill edge of Spiteful Geyser's crater an
independent geyser?

Also, I recall that a second vent existed here.  Was it, too, a geyser?

Thank you for your opinions on this issue.
