27615 15 Aug 2023 @ 1518 --- minissa Seems to be surging again with smallish, wispy butsts
23492 31 Aug 2022 @ 1303 --- Dave W Pyramid had a third eruption in the series at 1303. GeyserTimes rolled that entry underneath the 1258 eruption as a secondary eruption, so I have entered it here as a note as well.
18527 19 Jul 2021 @ 1627 --- minissa Noted small bursting play 6-9" from Splendid side of Daisy trail, not sure if this constituted pre-play but there was definitely no water when we were heading toward Black Sand Pool about an hour earlier
16110 13 Sep 2020 @ 1443 --- William pre-eruptive splashing, probably started within the previous 5m
16071 11 Sep 2020 @ 1900 --- William appeared post eruptive, light steam
1613 19 May 2015 @ 1430 19 May 2015 @ 1648 JSJ Observed Pyramid Geyser from 1430 to 1715. Very slight steaming or slight steaming alternated with no visible activity from 1430 to 1644. One spit at 1544. Small spitting at late 1625. Continuous spitting, progressing to low to moderately low spouting, from 1645 to 1648. Eruption at 1648 + ~55s to 1649 + 38s, followed by prominent post-eruption steaming.
