[Geysers] YNP seismographs

[Stephen P Shivers]

There are currently 4 Yellowstone seismic stations down due to severe 
icing conditions 
on a radio tower outside the park attenuating the radio signals below the 
squelch level.   Recent storms have left 3-4 feet of rime ice on this 
tower. 
Data will return with sunshine.
