<DIV><SPAN class=349362304-12082006> </SPAN><FONT color=#0000ff>I spent
most of my day in the Lower Basin, and here is something that I'd like input on
if possible-- I recall that somebody reported similar activity a month of two
ago and would appreciate a repeat of that recollection.</FONT></DIV>
<DIV><FONT color=#0000ff></FONT> </DIV>
<DIV><FONT color=#0000ff>I went out to Narcissus. At approximately 1200, it was
about 6 inches below overflow. Saying "Oh, well," I went on down to Underhill
Geyser. After finding it about as before (durations longer than the intervals,
one interval of 5 1/2 minutes), I returned to Narcissus. And there was water --
a LOT of it -- flowing down both runoff channels. But the water was still/again
fully 6 inches below overflow. At 1229 the water very abruptly rose, poured a
great volume of water over all outflow areas, pulsed vigorously and splashed as
high as 2 feet. It did this for about 2 minutes. I've never seen Narcissus do
anything so vigorous without an eruption, so I entered the time in my notebook,
as 1229. But then it stopped, and the water dropped down, you guessed it, about
6 inches. I waited. At 1308 the same event recurred. No eruption.</FONT></DIV>

<DIV><FONT color=#0000ff>This is completely "aberrant" behavior in my
experience. Does it sound simiar to anybody?</FONT></DIV>

<DIV><FONT color=#000000><SPAN class=349362304-12082006>I think I was the person
who reported something similar. On Monday 3 July Dick Powell and I
were at Narcissus doing the weekly data download at about 0830. We
noted an eruption of Labial at 0832ie, and my notes show Narcissus in "variable
overflow" from about 0830 to 0848 when there was a big surge that put a
considerable amount of water down the runoff channels, but in did not
result in an eruption. Within two minutes the water level was eight inches
or so below overflow. We left at that point, but the data logger
shows an eruption at 1021. The overflow surge that we saw registered also,
at 0851 (remember the logger has a one minute resolution, and that the sensor is
about five meters downstream). </SPAN></FONT></DIV>
