Friday was a wasted day, and pretty much covered in an earlier posting, except for one thing.
In years past, Grand would often undergo an interval mode shift sometimes between late April and early June. Just this time of year, actually. These mode shifts would mean that intervals would suddenly increase or decrease by a sizable amount, and often accompanied by dormancy or reactivation of Rift and West Triplet. In the last few days, I've noticed that Grand has stopped having short eruptiion intervals, even when all the signs say it should and could. Also, with last night's eruption, I've now seen in the past few days several eruptions where West Triplet did not erupt with Grand, and Percolator was quiet, too. (Actually, last night West Triplet came up to about a foot below overflow, blipped for less than a minute, then dropped.) This may be a simple fluctuation in behavior, or signal a shift in activity.
Unfortunately, in all those mode shifts, the burst count never seemed to be affected, good or bad.And just having mentioned out-loud the possibility means things are going to revert.
And nothing to do with geysers
At the bottom of one of the boxes of Yellowstone stuff that sat in the closet the last few years was something that I'm going to have to list on eBay under "Paper Memorabilia & Ephemera"
