4791 15 Sep 1980 @ 1800 --- research-mab 9/15/1980 Disturbance: Splutter Pot Geyser – did not follow the pattern of increased activity observed in its neighbor, Big Whirligig. Splutter Pot appears to be drowned out by the increased run off coming from Blue Geyser. Temp while water flowing into it- not ie 171ºF. Only one observed eruption at the end of a Big Whirligig.
5083 22 Jun 1980 @ 1800 --- research-mab 06/22/1980 Splutter Pot had an interval of 4min 30 sec between wash time.

5005 25 May 1979 @ 1800 --- research-mab 05/25/1979 the following geysers have been observed erupting: Blue, Africa, Fan or Fireball, Constant, Little and Big Whirligig, Splutter Pot, Steamboat and Echinus. Echinus seems to be quite erratic; reports of eruptions as short as two minutes and as long as 69.
5013 25 May 1979 @ 1200 --- research-mab 05/25/1979 Splutter Pot – in action frequently, perhaps every 10-15 minutes, often near beginning or end of activity from Whirligigs or Constant but that may just be coincidence 201º during minor splashing
5095 09 Jun 1978 @ 1800 --- research-mab 06/09/1978 Note Splutter Pot was seen in only one eruption. Temperature while not ie was 167ºF. Runoff in channel seemed much increased.
5103 14 Jun 1977 @ 1800 --- research-mab 06/14/1977 Splutter Pot remains quite active appears to be working in conjunction with Big Whirligig – splashes up to 2’
5102 02 Jun 1977 @ 1800 --- research-mab 06/02/1977 The small spring vent between the Whirligigs and Pinwheel was observed erupting to a height of 1 ½ ft. this morning.
5264 07 Aug 1976 @ 1800 --- research-mab 08/07/1976 There’s a hole, about bowling ball size, in the runoff channel about 20 yds north of Big Whirligig that was splashing around 6”-12”. This is the first time I’ve seen anything from this vent all summer.
5765 16 Aug 1974 @ 0828 --- research-mab 08/16/1974 Splutter Pot – marker washed out 0828 {NOTE: except for temps - usually 202º - this is the only mention of Splutter Pot in the 1974 logbook-mab}

6462 13 Sep 1972 @ 1800 --- research-mab 09/13/1972 Splutter Pot was full to overflowing this morning and “spluttering” a few inches high.
6451 03 Sep 1972 @ 1800 --- research-mab 09/03/1972 Splutterpot filled to within 6” of the top and “spluttering” a few inches above opening.
6448 02 Sep 1972 @ 1800 --- research-mab 09/02/1972 Sputter [sic] Pot Geyser – the vent has about 6 inches of water in it - the fullest that the vent has been all summer.
6415 16 Aug 1972 @ 1800 --- research-mab 08/16/1972 Splutter Pot- empty with sound of bubbling water audible
6409 15 Aug 1972 @ 1800 --- research-mab 08/15/1972 Sputter (sic) Pot Geyser – water in vent completely drained but boiling heard at depth.
6393 14 Aug 1972 @ 1800 --- research-mab 08/14/1972 Sputter sic] Pot G – water is now visible in the bottom of the vent for the first time this summer & it is sputtering but not to the surface.
6383 12 Aug 1972 @ 1800 --- research-mab 08/12/1972 Sputter [sic] Pot G – vigorous boiling can be heard at depth & all of the algae originally in the vent has been killed, however no water is visible
6472 02 Oct 1971 @ 1800 --- research-mab 10/02/1971 Sputter Pot, throwing water out at a low angle 6-12”
6833 06 Aug 1964 @ 1200 --- research-mab 08/06/1964 Blue – erupted in morning. Therefore there was no activity out of Pinwheel or Splutter Pot. {generic AM time}
No attachments for this geyser.
Baseline does not exist.
