I don't think it was a typo.<BR>
<BR>
Perhaps it is a matter of habit or convention that keeps us referring to Riverside intervals as "short" and "long" when there is not a major discontinuity in the distribution. (The same could probably be said for Old Faithful although it's been a couple years since I looked at the complete distribution of Old Faithful intervals.)<BR>
<BR>
Do we have a medium? At least in recent years, there hasn't been a clear-cut division between "short" and "long" because there hasn't been a wide discontinuity in the data set. For example, in 2008, using the 1246 eruption of Riverside (once again, thank you Ralph for making the data available), <BR>
<BR>
Interval: 6:15 6:16 6:17 6:18 6:19 6:20 6:21 6:22 6:23 6:24 6:25 6:26 6:27 6:28 6:29 6:30<BR>
Number of<BR>
observations<BR>
7 5 4 4 2 4 3 1 1 1 0 1 4 3 4 12<BR>
<BR>
I also should have added the disclaimer in the orginal post noting that the data was for January 1 through April 22, 2009. For this data set there was a 10 minute gap. That gap may already have been narrowed and even eliminated between April 22 and June 5, but data for that time period was not yet available, so maybe it wasn't so several weeks before I said the gap existed through April 22.<BR>
<BR>
People who know me say my favorite geyser saying is "After all, it's a geyser, it will do whatever it wants, whenever it wants."<BR>
<BR>
My second most favorite saying very well could be "A gap in the interval set doesn't mean the geyser can't erupt then; the gap is just a space in the distribution waiting to be filled in."<BR>

<DIV>It never did snow -- just periods of light cold rain in generally 40-50 degree temps. Seems the bulk of the storm is headed north and east of here, but we still expect wet conditions for the next several days.</DIV>
<DIV> </DIV>
<DIV>Yesterday I failed to mention that Dome began a series with 1225ie initial; it was still active into today's afternoon.</DIV>
<DIV> </DIV>
<DIV>Bronze Spring was active, per Mike Keller, with bursts of 1-2 feet repeating around every 10 minutes; his call was at 1239.</DIV>
<DIV> </DIV>
<DIV>Plumes of 61, 62 and 69; then 65 and 56 minutes.</DIV>
<DIV> </DIV>
<DIV>Beehive was, I think, 1521 -- I wasn't there, so this is a report from Jere via Webcam.</DIV>
<DIV> </DIV>
<DIV>Lion 0636ie initial, 0808, missed apparently, 1116 minor.</DIV>
<DIV> </DIV>
<DIV>Aurum 0905 and 1245.</DIV>
<DIV> </DIV>
<DIV>Castle 0105E major and trying to erupt as I departed around 1330</DIV>
<DIV> </DIV>
<DIV>The little Snake Eyes is erupting frequently, splashing to 1 and occasionally 2 feet for a few seconds.</DIV>
<DIV> </DIV>
<DIV>Grand around 0500 and then 1202 (T3Q). Again, note the number of bursts and the short intervals.</DIV>
<DIV> </DIV>
<DIV>Oblong 0952ns.</DIV>
<DIV> </DIV>
<DIV>Grotto in marathon, presumabley the same eruption that started at 1213 yesterday. It was still going at 1230 today. And no, Bijou was NOT completely shut down.</DIV>
<DIV> </DIV>
<DIV>Daisy running long: 0618ie, missed, and 1129.</DIV>
<DIV> </DIV>
<DIV>Riverside 0615 and 1236.</DIV>
<DIV> </DIV>
<DIV>Fan and Mortar appeared to have probably undergone an event cycle shortly before I got there at 0952. The following action was real garbage (I think): River Vent on 1013, off 1016; on 1019, Gold 1020, 1023 off, no Angle; 1025 RV on, 1028 Gold, off 1040 no Angle; 1047 RV on, 1052 Gold very weak splashing, and I left the scene.</DIV>
<DIV> </DIV>
<DIV>Great Fountain 1317, per Lynn.</DIV>
<DIV> </DIV>
<DIV>Labial 1450.</DIV>
<DIV> </DIV>
<DIV>Fountain 1457ie.</DIV>
<DIV> </DIV>
<DIV>And.... what I'm pretty sure was Kaleidoscope, which I haven't seen in a long time, 1457ie with a steady, slender column many 10s of feet high. It did not play again in the subsequent 5 minutes.</DIV>
