[Geysers] regarding Grotto Fountain

[TSBryan at aol.com]

That Grotto Fountain Geyser might have fallen into a dormancy should  perhaps 
be no surprise. (Actually, it was at one time known as "Surprise  Geyser"!)
 
As a double-check looking into Whittlesey and Marler, the first time that  
Grotto Fountain _might_ have been seen was 1875, when Strong noted three geysers 
 in simultaneous eruption. No doubt one was Grotto but what the other  two 
were/are is unknown -- Rocket (maybe), Grotto Fountain (maybe) and  South Grotto 
Fountain (maybe); shoot, maybe even Spa.
 
In 1886, Weed noted a hole "next" to Grotto's runoff as erupting to 30  feet. 
We suppose this was Grotto Fountain, but...?
 
And then the next known observation wasn't until 1927, then 1928 (2  
eruptions known), and 1931 (4 eruptions known).
 
There were eruptions during the 1940s (Surprise Geyser; Strange Geyser;  
etc.), but apparently Grotto Fountain was not consistently active until much  
later -- I seem to vaguely recall in the back of my muddled mind that its  
eruptions were still rather uncommon in the early 1970s.
 
NOW, bearing on this, what I don't recall reading is whether or not there  is 
still action in South Grotto Fountain.
