3697 20 Sep 2016 @ 1010 --- Janet Jones Sometime between 1010 & 1020 - Saw a good splash from it while at Avoca - maybe a foot high. The water of this splash filled the vent but very little splashed outside. Waited a bit to watch, but only saw spitting from it. There's another vent near Fumarole that also is wet around the edge, but I didn't see anything but a bit of spitting from that one.
No attachments for this geyser.
