Observations for 2025 June 13


It appeared that Rift erupted overnight, probably before midnight. Unlike yesterday, West Triplet did not eruption during the several hour wait at Grand, and never appeared to show wter in the vent.

Grand itself had a Turban Delay interval at our arrival. We finally got a One Burst Eruption two hours and six Turban eruptions later. The eruption was nicely backlit with what little wind pushing the steam to the north.

Afterwards went to investigate the progress on the boardwalk between Oblong and Giant. For a week, it seemed like nothing much, about 50 feet of new walkway. At least it looked like the new walkway is solidly built and won't immediately get bouncy like the old walkway.

The dumpster in front of Grotto was gone, replaced by one that gouged the paving material. Will be interested to see if there is any attempt to replair that damage.

Was surprised to see a second crew working on the Fan & Mortar walkway (the Oblong crew is on their weekend), where they were removing the old plastic walkway and replacing it with the newer boards.

Did a quick visit to East Sentinel, where it appears to be back to what I've considered its normal activity, with the murkiness gone.

In the afternoon it was a windy wait for Grand. Once again, I may have arrived during a Turban Eruption Delay. If so, this time it was six Turban eruption intervals before the One Burst Grand Eruption. We also got West Triplet ending just before the Grand eruption.
