This geyser report includes eruptions I saw and eruption times reported via
FRS radio.

I spent a total of about 3 hours in Biscuit Basin today over two observing
sessions, mainly taking intervals of Jewel and East Mustard and observing
the “Outpost” complex.  Avoca Spring, Shell Spring, and Rusty were all
undergoing frequent eruptions, but I did not record intervals for them.
Salt and Pepper and Island were also active.

Jewel intervals ranged from 7 to 9 minutes with an average of 8 minutes,
5 seconds for 23 closed intervals.  East Mustard intervals ranged from 8 to
10 minutes, with an average of 9 minutes, 3 seconds for 19 closed
intervals.  The actual eruption times for Jewel and East Mustard are
included in the report below.

I saw no eruptions of either “Outpost” or “Sentry”.  The first 55 minutes
of my observing session were spent down near Jewel, so it is possible that
“Outpost” erupted during that period and was not observed, although in past
years I have usually been able to see eruptions of “Outpost” from that
location.  By 1550, I had moved to the bench at the north end of boardwalk
near East Mustard and from then until 1655 and again from 1935 until 2040 I
had “Outpost” under observation and can definitively state that neither
“Outpost” or “Sentry” had any eruptions during those two separate 65 minute
windows.  The only eruptions I saw in the entire “Outpost” complex during
my observing sessions were a single 14-minute duration eruption of “Yellow
Bubbler” and an eruption from a feature I have not seen erupt before
located between “Outpost” and “Yellow Bubbler” about midway between those
two geysers right in front of a long narrow strip of grass running from
west to east.  This feature erupted to about 1 foot, with occasional
splashes reaching close to 2 feet.  I observed this feature in eruption at
1559 and it continued to erupt until 1608 for a duration of at least 9
minutes.  I also observed a shallow depression on the north-northeast edge
of “Outpost” fill with water and bubble for several minutes and then drain
on three separate occasions.  During one of these fills, I could hear
slight gurgling in “Outpost” and saw a couple of small splashes of water
just break the surface.  This ended after about 60 seconds and I saw and
heard nothing further from “Outpost” for the remainder of my observation
