[Geysers] Grotto shenanigans, and a researcher question

[carolyn loren]

Yesterday 2/18 I saw South Grotto Fountain at 0958 i.e. and post-marker-placement at 1022 i.e., and a visitor saw it still erupting at 1215 i.e.  Grotto finally started near 1219 i.e.   
 
This morning 2/19  Grotto was i.e. at 0933, Old Tardy and West Triplet at 0915 i.e., Pyramid at 0958 i.e., Oblong at 1003 i.e., and Daisy at 1008.
 
A guide just saw Aurum at 1348.
 
The question is about Lone Star.  The plaque on the wooden platform where the notebook is says that Lone Star has had a 3 hour interval since 1872.  Does that statement come from a reliable source?  Geysers of Yellowstone doesn't go quite so far...  We've also noticed last summer, and to the extent we know this winter, that Lone Star sometimes jumps around an hour or two one day to the next.  Lots of minors perhaps?  Anyway, thanks!
