30817 06 Aug 1988 @ 1800 --- research-mab 8/6/1988 - no time noted - Rediscovered Geyser, along the old road bed, appears to be spouting most of the time, although it is observed sporadically at best. The water usually goes less than 12” high.
30805 02 Jul 1988 @ 1800 --- research-mab 7/2/1988 - no time noted - Rediscovered Geyser is erupting. The Geyser below Rediscovered was full of water & showed overflow, but was not erupting.
30907 22 Jul 1986 @ 1200 --- research-mab 7-22–86 - no time noted - Rediscovered Geyser was erupting today. Temp of 200º
30924 12 May 1985 @ 1200 --- research-mab Sunday May 12 1985 - no time noted - Rediscovered G was in eruption to 3’ at 4:16 pm;
31438 02 Aug 1981 @ 1200 --- research-mab Sunday August 2 1981 The Basin Wide Disturbance has occurred! - no time noted - Rediscovered Geyser – 202º splashing to 3’ erupted for at least 5 minutes which is fairly long if I remember correctly.

5249 01 Sep 1976 @ 1500 --- research-mab 09/01/1976 Redicsovered was drained & dry at about 1500
32496 22 Aug 1976 @ 1630 --- research-mab 08/22/1976 Rediscovered Geyser was almost completely full of water but not erupting at 1630, had drained away to almost nothing by 1700
32490 20 Aug 1976 @ 1645 --- research-mab 08/20/1976 Rediscovered was down about 1’ from high water level when checked at 1645. The run-off channel was dry and looked as if it hadn’t had any water for some time.
32358 03 Jun 1976 @ 1630 --- research-mab June 3 1976 Rediscovered geezer – pool nearly empty at 4:30. Faint bubbling.
32348 27 May 1976 @ 1404 --- research-mab May 27 1976 - Rediscovered geezer nearly completely drained 1404 – no bubbling
32682 28 Aug 1975 @ 1350 --- research-mab 08/28/1975 Rediscovered geezer was full at 1350, then drained almost completely – wasn’t erupting.
32665 23 Aug 1975 @ 1628 --- research-mab 08/23/1975 - quieted down to nothing at 1628. {that figures}
5637 18 Aug 1975 @ 1800 --- research-mab 08/18/1975 Rediscovered geezer observed for about 20 min {time unknown}. During this time, the water level rose & fell about 7 times. When the level fell below 8” in depth, bubbling ceased. Above this level, the geezer bubbled & splashed. At its highest point, the water never caused an overflow.
32658 17 Aug 1975 @ 1148 --- research-mab 08/17/1975 Rediscovered geezer – drained at 1148
5633 06 Aug 1975 @ 1800 --- research-mab 08/06/1975 was observed for a 30 min period. The water level rose & fell 5 times. At the peak of each level, large steam bubbles rose & broke at the surface. At the low point of each level, a dull thudding could be heard. Temperatures were taken during the “boiling” phase (202ºF) & the “drained” phase (198ºF). No evidence of a recent eruption, as sinter area was quite dry. {no time entered}
