[Geysers] A couple of things from White Creek, 7/9/2010

[David Schwarz]

   I was just out at White Creek.  First, "Filial" remains active on
frequent intervals.  The creek was too high to cross comfortably, but we
watched it from near Tuft.

   Tuft appears to be recently dormant, or at least having extremely long
intervals.  It's periodically having weak overflow--just enough to wet its
runoff channel.  The cyanobacteria mats at the end of the channel are dying
out and dying, and the formation of Tuft itself is very dry except for what
appears to be steam condensation immediately around its pool.  Eclipse does
not appear to be doing anything, but the large pool connected to both of
them is having periodic overflows which are forming a new channel and
slightly flooding the surrounding area.

   Probably not related, a narrow but cavernous hole below Tuft, next to the
dying cyanobacteria beds had a loud, thrashing, but largely subsurface
eruption while we were watching Tuft not do anything.
