[Geysers] 5/4/16 F&M 1240

[Michael Goldberg]

Hi Tom,

Thanks very much for the report.

I'm not well versed in F&M's habits in the last 5-10 years, but my 
impressions of the video clips are:

1236 -- It looks odd to me, but I think F&M has experimented with the 
"high vent lock" in some of its more recent activity.  I would also guess 
that it's been responsible for more than its share of "false locks."

1238 -- Sure, Gold vent isn't very tall, but that kind of activity would 
get me excited every time.  All three vents (High, Gold, Angle) are nearly 
continuous, Gold is full of water, and I'll ignore the fact that Angle is 
jetting mostly steam.  Never liked Angle much anyway...

Glad to hear that the rocks are active again.  Not surprised to hear that 
they are still being creative with their preplay.
