[Geysers] new Biscuit geyser

[Mike Keller]

With permission from the NPS, I went out to the new geyser.  It is about 160
feet downstream from the footbridge on the western bank.  In the area around
this feature there are several new patches of hot ground and hot water is
seeping out in many areas.  The erupting feature is about 12 feet from the
river in an area where I have never known a vent to be.  There is a heavy
amount of black obsidian sand coming from this feature and the others in the
area.  I am beginning to think it is perpetual as I have yet to see it off
or speak with someone else who has.  The vent is about 4 feet long and has
no evident sinter within it.  There is a small gravel cone being built up
around it.  Another of these cones is found about 3 feet to the south, but
that feature is no longer erupting.  There is steady overflow into the
river.

Please help a poor soul who is unhappily stuck in southern California...

 

Looking at the USGS thermal map of Biscuit Basin, there is _nothing_ shown
anywhere near the Firehole River downstream from the footbridge at Biscuit
Basin. Nothing. Mike Keller reported this new geyser as "on the western
bank" of the river. I would request to know how many feet from the river
and, if it has been checked, is there evidence of any blowout there? (Bear
in mind the 20th Century history of how Black Opal and Wall formed.)

 

Thanks.
