Depression:  Marler--Prior
to the earthquake I had observed but few eruptions; they were of infrequent
occurrence.  Steady overflow
characterized it most of the time.   Dome:  Marler--"Prior to my own there is but one known reference to this
spring.  "The pool on the high mound
is a geyser altho [sic] not often seen in eruption.  It plays with much power and its eruptions
are like those of a miniature Giantess" (Phillips, 1927, p. 143).

>From the time of the above writing until 1959
there is no evidence of Dome ever having erupted."Grotto:  This paragraph from Marler may be the source of the myth that Grotto was dormant when Giant was active in the early 1950s:   

During the early part of the 1952 season I became aware that
there was a noticeable decline of activity in the Grotto Group.  Following this observation Grotto was given
special focus as a possible cause of Giant's increase in activity.  It soon became apparent that a pronounced
sympathy existed between the two groups. 
An eruption of Giant acted as a precursor to an eruption of Grotto,
whose eruption came about 45 minutes following the start of Giant.  Except for a series of 3 or 4 eruptions of
about 40 minutes duration, coming as a sequence to an eruption of Giant, Grotto
was in large measure dormant during the 1952 season.  A few times Grotto erupted when the quiet
phase of Giant was about 48 hours old. 
With but two observed exceptions, this was an unfailing herald of a
delayed eruption of Giant.  The eruptions
of Grotto which occurred during the quiet phase of Giant preceded an  eruption of Giant by about 10 hours.  On two occasions, the exceptions alluded to
above, instead of the eruption of Grotto delaying Giant, they both erupted near
simultaneously.

Little Squirt:  Prior
to 1959 it had been very irregular in its action.  During most seasons no eruptions were
observed.  Oblong:  Not completely dormant but from mid-1993 through mid 1996 there were only a few eruptions. On the other hand, Micah will be glad to know I haven't found any references indicating there have been any periods of dormancy exhibited by Anemone. OK, that's all I'm posting on this topic.  Maybe someone wants to write an article for The Sput or Transactions.  (If someone does take me up on this suggestion, please let me know and I'll remove the idea from my "idea" file.)
