[Geysers] Grand interval is changing?

[Ralph Taylor]

I don't have data for 50 years, but the GOSA website has data since 1997.  A
graph of 1-week moving median intervals is at

True. 
You all have a lot more resources than I do. A LOT MORE! I actually meant to
phrase that as a question and it did not come out that way - like my aunt
and I were talking and she remembers it being shorter at this time - not
hugely so like it is now, but noticeable - is this true? Didn't come out
that way and I am sorry for that. I am curious actually as I explain later
down. Very curious. 
I have hear-say and the memory (which as a trained historian you know is
never spot on - in fact can often be different). Case and point - none of
the group I was with remember others being there for Excelsior - I was three
- I remember water and rainbows. Jeannine remembers thinking it was odd
there were no others around - and as I have seen - because of the awesome
records you all have - there were others. Which is great! Still the number
was less than twenty, but more than the six I was originally told (by Rick
of all people - to start - oh the lies - which he never amended and he knew
better!). *Bows to the master keeper of knowledge* 
Rick used to tell me all kinda of cool things about the park and I remember
it, but it was all random facts, nothing like that - I was a kid - short
attention span - theater.  How high the water falls were, the biggest mud
pot bubble he had seen, how many coyotes he had seen that day - random stuff
like that. Talking about times where I had to sit and wait was boring. Mark
for the intelligence of the man to not expend energy when it was needed. I
did not get an appreciation for that until twenty long after Rick had passed
sadly. 
I (now this is personal and a huge project so no one go off and do this
unless you are already (seriously 100 plus years of data) - I do not have
the time and so why should you all have it! Stats was a evil class - but
since I now know all about it my brain is active on that kind of information
- standard deviation and things.) would love to see like a chart of the
averages over the years. With this year being such a huge change I would be
curious to see how many other dips there were (you know more than a half an
hour off) in time. I know you say this is unprecedented (which makes it
doubly interesting), but I am curious if we have other outliers - just
because they are far more interesting than the norm - as you state! 
My little historian brain is all excited now to hear what the masters have
in store. I find this all fascinating. I really do. History is so amazing to
me, though I study more pre-history due to my backgrounds and friendships
with tribal elders. 
A
PS. On a different note -speaking of historian brains - what do you all have
on the fish trap in Yellowstone Lake? I have the native versions - I am
curious if there have been any arch studies on it or anything. Just curious
what the Tomes have to say since this forum has amazing knowledge!

I beg your pardon re your aunt's memory, but the 5-6 hour intervals were
indeed unprecedented.   And not just the short intervals but the astonishing
reegularity were both unique.

What is interesting is I was talking to my aunt about this. Many of you know
her as Jeannine Wagner (Montgomery). She was pointing out that this is not
unheard of for Grand, but the average has been so long at 7-9 hours it is
what most remember. There was a couple years - around when I was born, that
she remembers it having this happen, but it was short lived. We should watch
to see if this lasts more than six months or is just a short lived thing. 
I am curious myself though. Lots of interesting things going on. Also
welcome back Plume. It was so weird being there in September and not seeing
it on Geyser Hill.
