Observations for 2025 June 05


Arrived at the bike rack by Castle to find Rift in eruption. For the next 2-1/2 hours got a series of short duration and short interval Turban eruptions. When Grand finally did erupt, Rift was still in eruption. The first burst lasted long enough to be a One Burst Eruption, but not long enough to prevent a second burst. It turns out that after a 70 second wait, we were rewarded with an explosive start to a second burst.

Rift quit sometime during Grand's eruption, and Vent & Turban were only off for about six minutes before their restart.

Uncertain looked promising, but while it made a lot of noise gurgling, there wasn't much visible splashing, and after a half hour or so, the vent was mostly quiet.

Then it was time to go over to Geyser Hill to wait for Beehive. Not a long wait, and the wind ended up cooperating. At first it appeared that the railing was going to get inundated, but the wind shifted enough that by the end of the Beehive eruption, the wall of spray was crossing the river and forcing spectators over there to move.

After noon there was a nice short wait for a less than seven hour One Burst Grand eruption interval.
