11009 20 Apr 2019 @ 1447 --- Micah Kipple What appears to be Round Geyser in the myriad group is having periodic visible boils perhaps 1-2 feet over the rim. A gazer familiar with the group is coming to confirm shortly.
3430 05 Aug 2016 @ 1953 05 Aug 2016 @ 2007 JSJ Brief, moderately low spouting from 1953 to 2001 from a feature west of White Geyser - possibly Round Geyser, based on sight line from Three Sisters Spring (where I was observing), using a labeled satellite photo. No more spouting seen between 2001 and 2007.
