---------------------------------------------------------------------------- A Note on Intervals: Intervals have been computed in cases where observations are for consecutive eruptions. In cases where observations are not known to be consecutive, intervals have not been computed. Intervals computed when both observations were "ie" are noted with a preceding * (e.g. *2:16). ---------------------------------------------------------------------------- Geyser Log abbreviations ie in eruption (wasn't observed at start) d duration I interval h height 3h45m15s "3 hours, 45 minutes, 15 seconds (for instance)" > greater than < less than ns "near start (the top of a steam column is observed still rising--when in doubt, ie is use d)" ini "initial-used for Lion, for instance" MJR major min minor ind indicator-used for Beehive vr "Visitor Report-it can be logged, (a reliable report) but the time might not be accurate" B "bursts as in Grand or Plume, recorded for instance as 3B" of overflow p "pause, time between 1 meter boil and burst from Great Fountain" Grand Eruption Codes: Interval type Dn Grand erupted n Turbans after long interval D0 Grand erupted on long Turban interval N No long Turban interval observed Starting Geyser T Turban G Grand Bursts n n bursts n+m n bursts plus m afterbursts * long 2nd burst (d>1m15s) # long 3rd brust (d>1m15s) Vent & Turban after C Continue Q Quit ---------------------------------------------------------------------------------------- Time Interval Duration Preplay Height Prediction Old Faith.
