| Comments: | Undetermined geyser in the Tangled Creek Group (Lower Geyser Basin) - same geyser that was reported on 26 July 2017. Eruption from 1853 to 1854 with semi-decent spouting (~one-third to one-half the height of UNNG-TGG-1's eruptions). Using Butch Bach's (1980) Tangled Creek Group map and Google Earth 2013 & 2016 satellite imagery, geyser may be Mat Spring (a little east of Pair Geyser) or an UNNG 10 meters west-southwest of Bell Geyser or an UNNG 13 meters ~due-west of Bell Geyser, or maybe something else. Sight line-wise, geyser is located almost exactly halfway between the right edge of Pair Geyser & the left edge of Orange Spring, as seen from the end of the White Dome Geyser boardwalk. |
