[Geysers] Geysers taken for granted

[TSBryan at aol.com]

Let it be noted that Old Faithful belongs on the list of geysers with known 
 dormancies -- at least one. The description by Ferris in the 1830s 
describes  several geysers but notably nothing that could be Old Faithful. And in 
fact,  although there were rather few visitors to the Upper Basin during the 
mid-1800s,  there were some, and there is NO description of an Old Faithful 
eruption until  1864. Not to mention the silicified wood within the cone 
formation, and other  such proofs of inactivity.

"Lynn's recent listserv discussion on Giantess intervals  has lead me into 
thinking of geysers in terms of decades and centuries.   Most of the big 
geysers have extended dormancies.  And I started  wondering what geysers we 
might be taking for granted  today."

Short answer:  The only "major" geysers that don't  seem to have periods of 
dormancy are Great Fountain, Old Faithful, and  Riverside.  Even some of 
the medium size geysers have had years of  dormancy.
